Answer:

Molar mass of acetic acid = 60 g/mol

Explanation:

Molar mass of any compound is the sum of the atomic masses of all the atoms of elements present in it.

Molar mass of acetic acid:

Formula:

CH₃COOH

Atomic mass of carbon = 12 g/mol

Atomic mass of hydrogen = 1 g/mol

Atomic mass of oxygen = 16 g/mol

Molar mass of acetic acid = 12×2 + 1 × 4 + 16× 2

Molar mass of acetic acid = 60 g/mol

if the reaction occurs in the laboratory and produces 2.8 moles of ammonia, calculate the percent yield for the experiment. Use

Helen [10]

The question is incomplete, here is the complete question:

The Haber process can be used to produce ammonia, $NH_3$ and it is based on the following reaction.

$N_2+3H_2\rightarrow 2NH_3$

If the reaction occurs in the laboratory and 5 moles of each hydrogen and nitrogen gas reacts and produces 2.8 moles of ammonia, calculate the percent yield for the experiment. Use the quantity of the product that is produced by the limiting reagent as the theoretical yield.

Answer: The percent yield of the reaction is 84.08 %.

Explanation:

We are given:

Moles of nitrogen gas = 5 mole

Moles of hydrogen gas = 5 mole

For the given chemical equation:

$N_2+3H_2\rightarrow 2NH_3$

By Stoichiometry of the reaction:

3 moles of hydrogen gas reacts with 1 mole of nitrogen gas

So, 5 mole of hydrogen gas will react with = $\frac{1}{3}\times 5=1.67mol$ of nitrogen gas

As, given amount of nitrogen gas is more than the required amount. So, it is considered as an excess reagent.

Thus, hydrogen gas is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

3 moles of hydrogen gas produces 2 moles of ammonia

So, 5 moles of hydrogen gas will produce = $\frac{2}{3}\times 5=3.33mol$ of ammonia

To calculate the percentage yield of ammonia, we use the equation:

$\%\text{ yield}=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100$

Experimental yield of ammonia = 2.8 moles

Theoretical yield of ammonia = 3.33 moles

Putting values in above equation, we get:

$\%\text{ yield of ammonia}=\frac{2.8mol}{3.33mol}\times 100\\\\\% \text{yield of ammonia}=84.08\%$

Hence, the percent yield of the reaction is 84.08 %.

the pressure in a sealed plastic container is 108 kPa at 41 degrees Celsius. What is the pressure when the temperature drops to

Katarina [22]

Answer: The new pressure will be 101.46 kPa.

Explanation:

To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.

The equation given by this law is:

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are initial pressure and temperature.

$P_2\text{ and }T_2$ are final pressure and temperature.

We are given:

By using conversion factor: $T(K)=T(^oC)+273$

$P_1=108kPa\\T_1=41^oC=314K\\P_2=?kPa\\T_2=22^oC=295K$

Putting values in above equation, we get:

$\frac{108kPa}{314K}=\frac{P_2}{295K}\\\\P_2=101.46kPa$

Hence, the new pressure will be 101.46 kPa.

Which of the following statements about the brain is true? a. The skull could support as much as 3 tons of weight. b. The brain

Thepotemich [5.8K]

Answer:

a. The skull could support as much as 3 tons of weight.

Explanation:

The true statement about brain is

a. The skull could support as much as 3 tons of weight.

The cranium(skull) bones are slot like a jigsaw puzzle together. All but one of these bones is fixed in place in adults. It makes the skull very solid. Babies have holes between the cranial (skull) bones so that as they are born, their heads may withstand being crushed.

rest all statements are wrong.
