Answers

Answer 1

Answer:

Heat flows from the coffee to the spoon through conduction

Explanation: I took did the lab assignment

Answer 2

Heat flows from the coffee to the spoon through conduction. Therefore, option C is correct.

Conduction is one of the three main modes of heat transfer, alongside convection and radiation. It refers to the transfer of heat energy through direct contact between objects or substances that are at different temperatures.

Conduction occurs more efficiently in materials that are good conductors of heat, such as metals, which have closely packed atoms and free electrons that can easily transfer thermal energy. Materials with poor conductivity, such as insulators like wood or plastic, impede the transfer of heat by conduction.

It the air in a carton of milk was allowed to warm up, what would happen to it?

Answers

Answer:

Very Likely B.

Explanation:

Increasing temperature inside a closed container - keeping everything constant will make pressure increase. Because the energy being held by the molecular (the gas molecules) rises, the container may expand meaning the volume increases.

Heated air would go into the solution in the milk if the air in a carton of milk was allowed to warm up with increased pressure. Hence, option B is correct.

What do intermolecular forces do?

Intermolecular forces hold multiple molecules together and determine many of a substance's properties.

Increasing temperature inside a closed container while keeping everything constant will make pressure increase due to a rise in the randomness of the molecules.

The volume of the air would attempt to increase with temperature, so the carton (if flexible) could begin to swell under the increased pressure, possibly to the point that it would leak out of the carton or even burst the seam.

Also, but of less importance, more of the heated air would go into the solution in the milk.

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type. ___P4 + ___O2 ⟶ ___P2O3

Answers

According to the conversation of mass, mass cannot be created or destroyed. This means whatever is done to one side, must be done to the other.

There are 4 Phosphorus atoms on the left, there must be 4 on the right. To do this, you must multiply the P2O3 by 2 to get 4 Phosphorus atoms and 6 Oxygen atoms. Now to balance the Oxygen atoms, you must multiply the oxygen atoms on the left by 3.

1 P4 + 3 O2 —-> 2 P2O3

Lastly, this equation type is synthesis (combination) because two reactants are becoming a single product.

Final answer:

To balance the chemical equation P4 + O2 -> P2O3, you need to place a coefficient of 5 in front of O2, resulting in the balanced equation P4 + 5O2 -> 2P2O3. This equation represents a synthesis reaction.

Explanation:

A balanced chemical equation is one that has the same number of atoms for each element on both sides of the equation. To balance the given equation, you need to determine the appropriate coefficients for the reactants and products.

In this case, you would balance the equation P4 + O2 → P2O3 by placing a coefficient of 5 in front of O2, resulting in the balanced equation  P4 + 5O2 → 2P2O3. This equation represents a synthesis reaction, where two or more substances combine to form a new compound.

Water is a common solvent in solutions. when a solute dissolves in water, the water molecules are attracted to and surround the individual solute particles. this process is called _____​

Answers

Answer: Hydration

Hydration is the process of solute particles being surrounded by water molecules arranged in a specific manner. Hydration helps to stabilize aqueous solutions by preventing the positive and negative ions from coming back together and forming a precipitate.

The process where solute particles become surrounded by water molecules when they dissolve is called solvation, or more specifically, hydration when water is the solvent. This allows polar or ionic solutes to form electrolyte solutions that can conduct electricity.

When a solute dissolves in water, the water molecules are attracted to and surround the individual solute particles. This process is known as solvation. If the solute is a liquid or a solid, its particles are separated from each other and completely surrounded by water molecules, entering the solution. When water is the solvent involved in solvation, the process is specifically called hydration. This is because water's polar nature allows it to engage in hydrogen bonding with the solute, effectively surrounding and isolating them within the solution.

Recall the rule that like dissolves like, which implies that a solute and solvent with similar intermolecular forces are likely to form a solution through the process of solvation or hydration. When ionic or polar solutes dissolve in water, they form electrolyte solutions which can conduct electricity, while nonpolar solutes form nonelectrolyte solutions that do not conduct electricity.

Answers

Answer:

2.5 x 10⁻² ≅ 3.0 x 10⁻² M.

Explanation:

Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.

M = (no. of moles of solute)/(V of the solution (L)).

∴ M = (mass/molar mass)of AgNO₃/(V of the solution (L)).

∴ M of AgNO₃ = (17.0 g / 169.87 g/mol)/(4.0 L) = 2.5 x 10⁻² ≅ 3.0 x 10⁻² M.

Answer: [tex]3\times 10^{-2}mol/L[/tex]

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n= moles of solute

[tex]V_s[/tex] = volume of solution in ml

moles of solute =[tex]\frac{\text {given mass}}{\times {\text {molar mass}}=\frac{17g}{170g/mol}=0.1moles[/tex]

Now put all the given values in the formula of molarity, we get

[tex]Molarity=\frac{0.1moles\times 1000}{4000ml}=0.03mole/L=3\times 10^{-2}M[/tex]

Thus molarity of the solution will be [tex]3\times 10^{-2}M[/tex]

number of grams of hydrogen than can be prepared from 6.80g of aluminum​

Answers

Answer:

0.7561 g.

Explanation:

The hydrogen than can be prepared from Al according to the balanced equation:

2Al + 6HCl → 2AlCl₃ + 3H₂,

It is clear that 2.0 moles of Al react with 6.0 mole of HCl to produce 2.0 moles of AlCl₃ and 3.0 mole of H₂.

Firstly, we need to calculate the no. of moles of (6.8 g) of Al:

no. of moles of Al = mass/atomic mass = (6.8 g)/(26.98 g/mol) = 0.252 mol.

Using cross multiplication:

2.0 mol of Al produce → 3.0 mol of H₂, from stichiometry.

0.252 mol of Al need to react → ??? mol of H₂.

∴ the no. of moles of H₂ that can be prepared from 6.80 g of aluminum = (3.0 mol)(0.252 mol)/(2.0 mol) = 0.3781 mol.

Now, we can get the mass of H₂ that can be prepared from 6.80 g of aluminum:

mass of H₂ = (no. of moles)(molar mass) = (0.3781 mol)(2.0 g/mol) = 0.7561 g.

Final answer:

In the given chemical reaction between hydrochloric acid and sodium bicarbonate, carbon dioxide (CO2) is the product that is a gas.Therefore, option D is the correct answer.

Explanation:

In the reaction HCl (aq) + NaHCO3 (aq) – NaCl (aq) + H2O (l) + CO2 (g), the product that is a gas is carbon dioxide (CO2). This reaction is typical of an acid (hydrochloric acid, HCl) reacting with a carbonate (sodium bicarbonate, NaHCO3), where the formation of carbon dioxide gas, water, and a salt (sodium chloride, NaCl) is observed. Such reactions often lead to effervescence due to the release of CO2 gas.

How many moles of HI are present at equilibrium when 2.0 moles of H2 is mixed with 1.0 moles of I2 in a 0.50 L container and allowed to react at 448oC. At this temperature K = 50.

Answers

Answer:

1.9 mol.

Explanation:

For the reaction:

H₂ + I₂ → 2HI,

The initial concentrations:

[H₂] = no. of moles/volume of the container = (2.0 mol)/(0.50 L) = 4.0 mol/L.[I₂] = no. of moles/volume of the container = (1.0 mol)/(0.50 L) = 2.0 mol/L.

The equilibrium constant (K) = [HI]²/[H₂][I₂],

Write down the equation and the start concentrations. Let (x) be the finish concentrations:

                 H₂       +      I₂     →     2HI

start:       4.0 M        2.0 M         0 M  

finish:     4.0-x         2.0-x           2x

The equilibrium constant (K) = [HI]²/[H₂][I₂] = (2x)²/(4.0 - x)(2.0 - x).

∴ 50 = (2x)²/(4.0 - x)(2.0 - x).

∴ 50 = (4x²)/(8.0 - 6.0 x + x²).

∴ 400 - 300 x + 50 x² = 4x².

∴ 46x² - 300 x + 400 = 0    (standard form)

Use the quadratic equation to solve for (x):

x = (- b ± √(b² - 4ac))/(2a),  

In this case a = +46, b = -300 and c = +400.

x = (+ 300) ± √((- 300)² - 4 (46)(400))/(2 (46))

x = (+ 300) ± √(9000 - 73600)/(92)

x = (+ 300) ± 127)/(92)

∴ x = 4.7 and 1.9

When  x = 4.7 is not possible, because 4.0 - 4.7 (the concentration of H2 would be negative).

So, x = 1.9.

∴ [HI] = 2x

If x = 1.9,

∴ [HI] = 2(1.9) = 3.8 mol/L.

∵ [HI] = no. of moles/volume of the container.

∴ no. of moles of (HI) = [HI]*volume of the container = (3.8 mol/L)(0.5 L) = 1.9 mol.

Origin of the name carbon dioxide

Answers

Final answer:

Carbon dioxide is named for its two oxygen atoms bonded to one carbon atom; the 'di-' prefix indicates two oxygen atoms. CO is named carbon monoxide instead, as the 'mono-' prefix is dropped when only one atom of the first element is present. Different numbers of oxygen atoms result in different compounds with distinct names and properties.

Explanation:

The origin of the name carbon dioxide comes from its chemical composition. Carbon dioxide is a compound made up of one carbon atom and two oxygen atoms. In chemical nomenclature, the prefix 'di-' stands for two, indicating the presence of two oxygen atoms. Thus, the name carbon dioxide tells us that there are two oxygen atoms bonded to a single carbon atom. The nearly universal practice in chemical nomenclature is to drop the prefix 'mono-' when there is only one atom of the first element, so CO2 is not called carbon monoxide but carbon dioxide.

Furthermore, compounds like CO (carbon monoxide) and CO2 require different names because they contain different numbers of oxygen atoms, which significantly changes their properties. When forming the names of these molecular compounds, the element that is more metallic (furthest left and/or bottom in the periodic table) is named first. Then follows the name of the more nonmetallic element (furthest to the right and/or top), with its ending changed to '-ide', and prefixed with a Greek numeral prefix to represent the number of atoms, if greater than one. Consequently, CO2 is named carbon dioxide due to the two oxygen atoms in its structure.

Atomic no. = 82

Atomic mass = 207.2 amu

No. of protons = 82

No. of electrons = 82

Yes, lead(Pb) is a metallic element and certainly it has 6 electron shells which means 6 energy level.

If you find anything unclear you can ask me...

Final answer:

The element with 6 energy levels, metallic properties, and 82 electrons is lead (Pb). This can be deduced from its position in the Periodic Table, specifically in period 6 and group 14, with an electron configuration that places its highest energy valence electrons in the sixth energy level.

Explanation:

To identify the element described as having 6 energy levels, being metallic, and containing 82 electrons, we should first refer to the Periodic Table. Elements with 6 energy levels are located in period 6 of the Periodic Table. The metallic element with 82 electrons is the well-known lead (Pb), which sits in the carbon family, group 14. It has the electron configuration [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p², indicating that the valence electrons (the electrons in the highest energy level) are in the sixth energy level. Lead is considered a representative metal because it is not a transition metal nor an inner transition metal, and its valence electrons fill the p orbitals after the s orbitals have been filled.

Furthermore, periodic trends such as metallic character help confirm that lead is the correct answer, as it has the properties expected of metals, such as the ability to lose valence electrons, and demonstrates high thermal and electrical conductivity.

if 4000 g of Fe2O3 reacts, how many moles of CO are needed?
(add work)

Answers

Answer:

75.15 mol.

Explanation:

Firstly, we need to write the balanced equation of the reaction:

Fe₂O₃ + 3CO → 2Fe + 3CO₂.

It is clear that 1.0 mole of Fe₂O₃ reacts with 3.0 moles of CO to produce 2.0 moles of Fe and 3.0 moles of CO₂.

∴ Fe₂O₃ reacts with CO with (1: 3) molar ratio.

we need to calculate the no. of moles of (4000 g) of Fe₂O₃:

no. of moles of Fe₂O₃ = mass/molar mass = (4000 g)/(159.69 g/mol) = 25.05 mol.

Using cross multiplication:

1.0 mole of Fe₂O₃ needs → 3.0 moles of CO,

∴ 25.05 mole of Fe₂O₃ needs → ??? moles of CO.

∴ The no. of moles of CO needed = (3.0 mol)(25.05 mol)/(1.0 mol) = 75.15 mol.

Final answer:

To react with 4000 g of Fe2O3, 75.15 moles of CO are needed based on the balanced chemical equation Fe2O3 + 3CO -> 2Fe + 3CO2 and the molar mass of Fe2O3.

Explanation:

To calculate the number of moles of CO needed when 4000 g of Fe2O3 reacts, we need a balanced chemical equation. The equation provided in different parts of the question suggests a discrepancy. For consistency, we will use the general reaction of iron(III) oxide with carbon monoxide: Fe2O3 + 3CO -> 2Fe + 3CO2. This stoichiometry of the equation indicates that one mole of Fe2O3 reacts with three moles of CO.

First, we determine the molar mass of Fe2O3, which is approximately 159.7 g/mol. Then, we calculate the number of moles of Fe2O3:

Moles of Fe2O3

= (Mass of Fe2O3) / (Molar Mass of Fe2O3)
                 = 4000 g / 159.7 g/mol
                 = 25.05 moles of Fe2O3

Next, using the stoichiometric ratio from the balanced equation (1 mole of Fe2O3 to 3 moles of CO), we can calculate the moles of CO required:

Moles of CO

= Moles of Fe2O3 × 3
               = 25.05 moles × 3
               = 75.15 moles of CO

Thus, 75.15 moles of CO are needed to react with 4000 g of Fe2O3.
