How do you balance the following equation only using coefficients?

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.

<u>Answer:</u> The percent yield of the reaction is 84.08 %.

<u>Explanation:</u>

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 %.

Select the correct answer from each drop-down menu. carbon is found in all living organisms. the constant flow of carbon on eart

Nady [450]

The continuous cycling of carbon in the earyh is known as the carbon cycle.

<h3>What is the carbon cycle?</h3>

The carbon cycle is a cycle which explains the various processes by which carbon is recycled between the atmosphere and the earth.

The constant flow of carbon on earth through organisms and the air is known as the carbon cycle. Plants absorb carbon from the atmosphere in the form of carbon dioxide. They use it for respiration and food production.

Animals consume plants, transferring carbon along the food chain.

Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.

Carbon enters back into the atmosphere in the form of carbondio dioxide.

Therefore, the continuous cycling of carbon in the earth is known as the carbon cycle.

An ion of oxygen has a charge of -2. How many protons and electrons does the ion have? ____protons ____electrons

jenyasd209 [6]

Oxygen has 8 protons and 10 electrons due to the addition of 2 electrons, determined from the ion charge. Likewise an ion of potassium has 19 protons and 18 electrons. Charge on fluorine would be -1 and charge on calcium would be +2. Atomic number is the same as the number of protons, so it would be 6, the mass number is the sum of protons and neutrons which would be 13, and the charge is 0, as it is an atom and not an ion.
