Question

WHAT IS COMBINATION REACTION?​

Answer 1

Answer:

A combination reaction is a reaction in which more than one element or compound combine to form a single compound only.

Explanation:

A general form is

A + B (reactants can be more than two) -----> C (product is only one)

For example,

2Mg + O₂ ---------> 2MgO

2Cu + O₂ ---------> 2CuO

Ca(OH)₂ + H₂O +  CO₂ -----------> Ca(HCO₃)₂

Answer 2

Answer:

Combination reaction is chemical reaction where two substances combined to form a compound.

Form: A + B ➜ C

Here, A and B are the reactants of the reaction and C is the product.

Examples:-

• H2 + O2 ➜ 2 H2O
• Mg + H2O ➜ Mg(OH)2
