**Balancing Chemical Reactions Guide**

Balance the reactions. A hint is provided to help you decide if the reaction will proceed as written, i.e., from left to right. Do not leave any fractions.

---

1. **Balance**  
   \[\text{Al}_2\text{O}_3 \rightarrow \text{Al} + \text{O}_2\]

   b) What type of reaction is this?  
   c) Is this a redox reaction, yes/no?  
   d) The reaction will go from left to right, yes/no?  
   *(Hint: O\(_2\) is very reactive)*

---

2. **Balance**  
   \[\text{HNO}_3 + \text{Al} \rightarrow \text{H}_2(g) + \text{Al}(\text{NO}_3)_3\]

   b) What type of reaction is this?  
   c) Is this a redox reaction, yes/no?  
   d) The reaction will go from left to right, yes/no?  
   *(Hint: Aluminum is a reactive metal, and a gas escapes)*

---

3. **Balance, leave no fractions**  
   \[\text{C}_7\text{H}_{14} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O}\]

   b) What type of reaction is this?  
   c) Is this a redox reaction, yes/no?  
   d) The reaction will go from left to right, yes/no?  
   *(Hint: O\(_2\) is very reactive)*
