Answer 1

1. A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.It's a type of chemical reaction in which two or more simple substances combine to form a more complex product.The reactants may be elements or compounds. The product is always a compound.
2. Synthesis reactions release energy in the form of heat and light, so they are exothermic.
3. Example:

• The formation of water from hydrogen and oxygen..[ 2 H₂(g) + O₂(g) → 2 H₂O(g) ]
• Synthesis of Ammonia..[3 H₂(g) + N₂(g) → 2 NH₃(g) ]
• Synthesis of Iron Sulfide..[8 Fe + S₈ → 8 FeS]
