Answer:
Synthesis reaction:
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
All other options are incorrect because,
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Combustion reaction:
In combustion reaction substances are react with oxygen and produces carbon dioxide and water.
Answer:
O2+H2 → H2O
become→zero to−2
∵ it will be reduced and oxidation state of H
2
becomes zero to +1 it will be oxidised.
∴ reaction will be redox
