Answer:
a. single replacement
Explanation:
Chemical equation:
Cd + H₂SO₄ → CdSO₄ + H₂
In given reaction Cd replace the hydrogen and form cadmium sulfate and hydrogen gas.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Other options are incorrect because,
Combustion:
In combustion reaction substances are burn in the presence of oxygen and form carbon dioxide and water.
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
The answer is A for number 1 and D for 2
