![### Chemistry Reactions Practice
The following exercises involve writing balanced chemical equations for each described reaction. Fill in the blanks with the correct chemical formulas and balance each reaction.
**a. Combustion of Ethanol**
- The combustion of ethanol (\( \text{C}_2\text{H}_5\text{OH} \)) forms carbon dioxide and water vapor. A combustion reaction refers to a reaction of a substance with oxygen gas.
\[
\text{C}_2\text{H}_5\text{OH} \quad + \quad \text{O}_2 \quad \rightarrow \quad \text{CO}_2 \quad + \quad \text{H}_2\text{O}
\]
**b. Reaction of Mercury(II) Nitrate and Sodium Phosphate**
- Aqueous solutions of mercury(II) nitrate and sodium phosphate are mixed, resulting in the precipitate formation of mercury(II) phosphate with aqueous sodium nitrate as the other product.
\[
\text{Hg(NO}_3\text{)}_2 \quad + \quad \text{Na}_3\text{PO}_4 \quad \rightarrow \quad \text{Hg}_3(\text{PO}_4)_2 \quad + \quad \text{NaNO}_3
\]
**c. Reaction of Manganese and Hydrochloric Acid**
- Solid manganese reacts with aqueous HCl to form aqueous manganese(II) chloride and hydrogen gas.
\[
\text{Mn} \quad + \quad \text{HCl} \quad \rightarrow \quad \text{MnCl}_2 \quad + \quad \text{H}_2
\]
**d. Reaction of Barium Hydroxide and Hydrobromic Acid**
- Aqueous barium hydroxide reacts with aqueous hydrobromic acid to produce water and aqueous barium bromide.
\[
\text{Ba(OH)}_2 \quad + \quad \text{HBr} \quad \rightarrow \quad \text{H}_2\text{O} \quad + \quad \text{BaBr}_2
\]
### Instructions
- Ensure each equation is balanced: the number of atoms of each element should be equal on both sides of the equation.
- Write the states of the compounds (such as \(aq\),](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe260a345-32eb-45b6-b01c-0d9ccee309e9%2F1ee18e6d-25eb-4b4c-94e2-5a8c7ebee2c4%2Fmypt9za_processed.jpeg&w=3840&q=75)
