![**Problem 5:**
**Question:** How many moles of H₂O can be formed from 1.71 × 10²³ atoms of NH₃ from the following equation?
\[ 4 \text{ NH}_3\text{(g)} + 5 \text{ O}_2\text{(g)} \rightarrow 4 \text{ NO(g)} + 6 \text{ H}_2\text{O(g)} \]
**Problem 6:**
**Question:** How many moles of HNO₃ will be produced from the reaction of 58.5 g of NO₂ with excess water in the following chemical reaction?
\[ 3 \text{ NO}_2\text{(g)} + \text{ H}_2\text{O (l)} \rightarrow 2 \text{ HNO}_3\text{(g)} + \text{ NO(g)} \]
**Problem 7:**
**Question:** How many grams of magnesium chloride can be produced from 4.81 moles of chlorine gas reacting with excess magnesium?
\[ \text{Mg(s)} + \text{Cl}_2\text{(g)} \rightarrow \text{MgCl}_2\text{(s)} \]
**Problem 8:**
**Question:** How many moles of NO₂ would be required to produce 7.25 moles of HNO₃ in the presence of excess water in the following chemical reaction?
\[ 3 \text{ NO}_2\text{(g)} + \text{ H}_2\text{O (l)} \rightarrow 2 \text{ HNO}_3\text{(g)} + \text{ NO(g)} \]
Each of these problems involves stoichiometry calculations based on balanced chemical equations.
