K2O(s)+H2O(l)-->KOH(aq)5a. is it a combination reaction, decomposition reaction, or combustion reaction

Answer 1

Answer :

(1) This reaction is a combustion reaction.

(2) This reaction is a decomposition reaction.

(3) This reaction is a combustion reaction.

(4) This reaction is a combination reaction.

(5) This reaction is a combination reaction.

Explanation :

Combination reaction : It is a type pf reaction in which the two or more molecules combine to form a larger single molecule as a product.

Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.

Combustion reaction : It is a type of reaction in which a hydrocarbon molecule react with the oxygen molecule to give carbon dioxide and and water as a product.

1. $C_3H_6(g)+O_2(g)\rightarrow CO_2(g)+H_2O(g)$

This reaction is a combustion reaction.

2. $NH_4NO_3(s)\rightarrow N_2O(g)+H_2O(l)$

This reaction is a decomposition reaction.

3. $C_5H_6O(l)+O_2(g)\rightarrow CO_2(g)+H_2O(g)$

This reaction is a combustion reaction.

4. $N_2(g)+H_2(g)\rightarrow NH_3(g)$

This reaction is a combination reaction.

5. $K_2O(s)+H_2O(l)\rightarrow KOH(aq)$

This reaction is a combination reaction.
