Explanation:
The Chemical Equations are;
H2CO3 --> H2O + CO2
8Cu + S₈ --> 8 Cus
BaCO3 --> BaO + CO2
P₄ + 502 --> 2P205
KCIO3 --> KCI + O2
8Fe + S₈ --> 8Fes
The Reactions are;
Synthesis Reaction
Decomposition Reaction
A synthesis reaction occurs when two atoms or molecules react to form a different molecule or compound.
A decomposition reaction; a compound breaks into two or more products.
H2CO3 --> H2O + CO2 (Decomposition reaction)
8Cu + S₈ --> 8 CuS (Synthesis reaction)
BaCO3 --> BaO + CO2 (Decomposition reaction)
P₄ + 502 --> 2P205 (Synthesis reaction)
KCIO3 --> KCI + O2 (Decomposition reaction)
8Fe + S₈ --> 8Fes (Synthesis Reaction)
Answer:
