Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Question

### Chemical Reaction and Stoichiometry Problem

**Problem Statement:**
How many grams of NH₃ are needed to completely react with 12.70 g of O₂? Furthermore, how many grams of H₂O would be formed in the reaction?

**Reaction Equation:**
\[ 4 \text{NH}_3(g) + 5 \text{O}_2(g) \rightarrow 4 \text{NO}(g) + 6 \text{H}_2\text{O}(g) \]

**Explanation:**
This balanced chemical equation represents the reaction between ammonia (NH₃) and oxygen (O₂) to form nitrogen monoxide (NO) and water (H₂O). The coefficients in the equation indicate the molar ratios in which the reactants and products participate in the reaction.

To solve the problem:
1. Convert the mass of O₂ (12.70 g) to moles using its molar mass.
2. Use the mole ratio from the balanced equation to find the moles of NH₃ required.
3. Convert the moles of NH₃ to grams using its molar mass.
4. Use the mole ratio to find the moles of H₂O produced.
5. Convert the moles of H₂O to grams using its molar mass.

This exercise involves understanding stoichiometry, which is fundamental in chemistry for predicting the amounts of substances consumed and produced in a chemical reaction.
