Answer :
To answer the question, here are two examples of synthesis reactions along with the reactants and products:
1. **Combination of Hydrogen and Oxygen to Form Water:**
- Reactants: Hydrogen gas (H2) + Oxygen gas (O2)
- Product: Water (H2O)
*Explanation:* In this reaction, hydrogen gas (H2) and oxygen gas (O2) combine in the presence of a catalyst like a spark or heat to form water (H2O). The chemical equation for this reaction is: 2H2 + O2 → 2H2O.
2. **Combination of Sodium and Chlorine to Form Sodium Chloride:**
- Reactants: Sodium metal (Na) + Chlorine gas (Cl2)
- Product: Sodium chloride (NaCl)
*Explanation:* When sodium metal (Na) reacts with chlorine gas (Cl2), they combine to form sodium chloride (NaCl). This reaction is highly exothermic and the chemical equation is: 2Na + Cl2 → 2NaCl.
These two examples illustrate synthesis reactions where simpler substances combine to form more complex compounds through a chemical reaction.
