Final answer:

To calculate the percent yield, the actual yield in moles of potassium permanganate was found to be 4.40 moles from 695.2 g, using the molar mass of KMnO4. Then, the percent yield was calculated using the theoretical yield of 5.00 moles, resulting in 88%.

Therefore, the correct answer is C. 88%

Explanation:

To calculate the percent yield of the reaction, we first need to know the moles of potassium permanganate (KMnO4) that correspond to 695.2 g. We use the molar mass of KMnO4 which is 158.04 g/mol to convert grams to moles.

Actual yield in moles = mass (g) / molar mass (g/mol) = 695.2 g / 158.04 g/mol = 4.40 moles of KMnO4

Now, with the theoretical yield of 5.00 moles, we can find the percent yield using the formula:

Percent yield = (actual yield / theoretical yield) × 100%

Percent yield = (4.40 moles / 5.00 moles) × 100% = 88%

Therefore, the correct answer is C. 88%

Answer:

[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]

Step-by-step explanation:

We have been given several numbers and we are asked to order them in least to greatest order.

Given numbers: [tex]2.8, 2.8\times 10^2,2.8\times 10^{-3},2.8\times 10^4,2.8\times 10^{-5}[/tex]

We know that the number with negative power will be smaller than the number with positive powers.

We can see from our given numbers that [tex]2.8\times 10^{-5}[/tex] has a negative power. We can rewrite this as [tex]2.8\times \frac{1}{10^5}[/tex]. This will be the smallest number.

Upon arranging our given number from least to greatest we will get,

[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]

Answer: The answer is 16 by 32.

Step-by-step explanation:

I took the test and this was correct. Explanation is easy because 12 is 3/4 of 16 and 24 is 3/4 of 32.

If the generic television set is 12 inches by 24 inches, the dimensions of the brand name television is, 16 inches by 32 inches

Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.

Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.

Given that,

Jason considered two similar televisions at a local electronics store

The generic version was three fourths the size of the brand name

The generic television set is 12 inches by 24 inches

The dimensions of the brand name television = ?

Suppose, the dimensions of the brand name are a  inches by b inches

So,

3/4 a   =  12

a   =  16

Similarly,

3/4 b = 24

b  =  32

Hence, the dimensions are 16 inches by 32 inches

The interpretation is (c) the rate of change of the cost of the taxi ride is $2.00 per minute.

The function is given as:

c(x) = 2x + 4.00

A linear equation is represented as:

c(x) = Slope * x + y-intercept

By comparison, we have:

Slope = 2

This means that the slope of c(x) = 2x + 4.00 is 2

Hence, the interpretation is (c) the rate of change of the cost of the taxi ride is $2.00 per minute.

Answer:

1. 345 dollars

2. 97.125 dollars

Step-by-step explanation:

1) What are the earnings for 5 days at 69 dollars a day?

If a person makes 69 dollars a day and we want to know the earning of 5 days, we would have to multiply the earnings per day by the number of days.

69 x 5 = 345.

2) What are the earnings for 3.5 days at 27.75 dollars a day?

If a person makes 27.75 dollars a day and we want to know the earning of 3.5 days, we would have to multiply the earnings per day by the number of days.

27.75 x 3.5 = 97.125

Answer: Composite

Step-by-step explanation: To see if 35 is a prime number or a composite number, let's first start by finding the factors of 35.

To find the factors of 35, begin by dividing 35 by 1 which gives us 35. This means that 1 and 35 are factors.

Next, since 35 is not divisible by 2, 3, or 4, we divided 35 by 5 which gives us 7. This means that 5 and 7 are factors.

Next, since 35 is not divisible by 6, we divide 35 by 7 which gives us 5. Notice that 7 and 5 are repeat factors and once we hit repeat factors, this means that all other factors we try will repeat.

Therefore, the factors of 35 are 1, 5, 7, and 35.

Since 35 has more than two factors, it's called a composite number.

Final answer:

To find the missing number in the equation 6.02 + 1.3 - __ = 4.39, you need to first add 6.02 and 1.3, and then subtract the result from 4.39 to obtain the missing number, which is -2.93.

Explanation:

What you need to do in this question is solve for the missing number to make the equation true: 6.02 + 1.3 - x = 4.39.

First, add 6.02 and 1.3: 6.02 + 1.3 = 7.32.

Next, subtract 7.32 from 4.39 to find the missing number: 4.39 - 7.32 = -2.93. Therefore, the missing number is -2.93.
