C5H6O(l)+O2(g)-->CO2(g)+H2O(g)3a. is it a combination reaction, decomposition reaction, or combustion reaction4.N2(g)+H2(g)-->NH3(g)?4a. is it a combination reaction, decomposition reaction, or combustion reaction5. K2O(s)+H2O(l)-->KOH(aq)5a. is it a combination reaction, decomposition reaction, or combustion reaction

Answer 1

1. C3H6(g) + O2(g) → CO2(g) + H2O(g) is a combustion reaction.

2. NH4NO3(s) → N2O(g) + H2O(l) is a decomposition reaction.

3. C5H6O(l) + O2(g) → CO2(g) + H2O(g) is a combustion reaction.

4. N2(g) + H2(g) → NH3(g) is a combination reaction.

5. K2O(s) + H2O(l) → KOH(aq) is a combination reaction.

Step-by-step explanation:

To balance the given chemical equations and identify the type of reactions, follow these steps:

1. C3H6(g) + O2(g) → CO2(g) + H2O(g): This is a combustion reaction. The balanced equation is C3H6 + 9/2 O2 → 3CO2 + 3H2O.
2. NH4NO3(s) → N2O(g) + H2O(l): This is a decomposition reaction. The equation is already balanced.
3. C5H6O(l) + O2(g) → CO2(g) + H2O(g): Another example of a combustion reaction. The balanced equation is C5H6O + 15/2 O2 → 5CO2 + 3H2O.
4. N2(g) + H2(g) → NH3(g): This is a combination reaction. The balanced equation is N2 + 3H2 → 2NH3.
5. K2O(s) + H2O(l) → KOH(aq): This is a combination reaction. The equation is already balanced and indicates the formation of potassium hydroxide from potassium oxide and water.

Answer 2

(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.
