Question

Define combination and decomposition reaction.​

Answer 1

Answer:

l

Chemical combination

Chemical decomposition

Explanation:

1) Reaction in which single product is formed two or more reactants is called combination

eg:c+o²+gives rise to co²

2)In a reaction one compound dissociates into many is called decomposition.

eg:Caco3 gives rise to Cao+Co².

Answer 2

$\huge\underline\mathfrak\red{Answer}$

$\large{\boxed{\tt{Combination-Reaction}}}$

♦ The reaction in which two or more reactants combine to form a single product.

♦ A + B → AB

Ex: C(s) + O2(g) → CO2(g)

$\large{\boxed{\tt{Decomposition-Reaction}}}$

♦ The reaction in which a compound splits into two or more substances is called decomposition reaction.

♦ A → B + C

Ex: H2O(l) → H2(g) + O2(g)
