**Chemical Reactions Balancing Exercise**

Balance the following chemical reactions and indicate the type of reactions:

a. \_\_ ZnS + \_\_ HCl → \_\_ ZnCl₂ + \_\_ H₂S  
   - Type: \_\_\_\_

b. \_\_ HCl + \_\_ Cr → \_\_ CrCl₂ + \_\_ H₂  
   - Type: \_\_\_\_

c. \_\_ Al + \_\_ Fe₃O₄ → \_\_ Al₂O₃ + \_\_ Fe  
   - Type: \_\_\_\_

d. \_\_ H₂ + \_\_ Br₂ → \_\_ HBr  
   - Type: \_\_\_\_

e. \_\_ Na₂S₂O₃ + \_\_ I₂ → \_\_ NaI + \_\_ Na₂S₄O₆  
   - Type: \_\_\_\_

**Instructions:**

1. Fill in the blanks to balance each chemical equation.
2. Identify the type of reaction for each balanced equation (e.g., synthesis, decomposition, single replacement, double replacement, combustion).
