### Chemistry Stoichiometry Problems

#### Question 5:
**Calculate the number of moles of water produced by the reaction of 3.2 moles of calcium hydroxide.**

Chemical Equation:
\[ 
\text{__Ca(OH)}_2 + \text{__HNO}_2 \rightarrow \text{__Ca(NO}_2\text{)}_2 + \text{__H}_2\text{O} 
\]

#### Question 6:
**If 50.0 g of \(\text{Al}_2\text{O}_3\) is produced, what mass of Al reacted?**

Chemical Equation:
\[ 
\text{__Al} + \text{__O}_2 \rightarrow \text{__Al}_2\text{O}_3 
\]

#### Question 7:
**How many moles of propane (\(\text{C}_3\text{H}_8\)) will burn in 250.0 g of oxygen gas?**

Chemical Equation:
\[ 
\text{__C}_3\text{H}_8 + \text{__O}_2 \rightarrow \text{__CO}_2 + \text{__H}_2\text{O} 
\]

#### Question 8:
**What mass of CO is needed to produce 100.0 g of \(\text{CO}_2\)?**

Chemical Equation:
\[ 
\text{__CO} + \text{__O}_2 \rightarrow \text{__CO}_2 
\]

These problems involve applying stoichiometric principles to balance chemical equations, convert between grams and moles, and use stoichiometric coefficients to calculate the quantities of reactants or products.
