Question

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water . what mass of ammonia is consumed by the reaction of of oxygen gas? round your answer to significant digits.

Answer 1

The mass of ammonia consumed by the reaction of oxygen gas is 42.35 grams.

Step-by-step explanation:

The question asks for the mass of ammonia consumed by the reaction of oxygen gas. To find the mass of ammonia consumed, we need to use the balanced equation for the reaction:

4NH3 + 5O2 → 4NO + 6H2O

From the equation, we can see that for every 4 moles of NH3, we need 5 moles of O2. Therefore, the ratio of O2 to NH3 is 5:4.

Let's assume the mass of O2 consumed is x grams. Using the ratio, we can set up the following equation:

(x g O2) / (32 g O2/mol) = (4 g NH3) / (17 g NH3/mol)

Solving for x, we find that x = 42.35 g O2.

Therefore, the mass of ammonia consumed by the reaction of oxygen gas is 42.35 grams.

Answer 2

Let us suppose we are given with 4.2 g of oxygen. Then, the amount of ammonia required to consume all oxygen is 1.785 g. The solution is as follow,
