Decomposition reaction

Explanation:

Decomposition reaction:

It is the reaction in which one substance is converted into the two or more products.

The decomposition reactions always involved one substance to decompose.

General chemical equation:

AB   →   A + B

The given chemical equation:

NH₄NO₃(s)   →   N₂O (g) + H₂O(g)

Ammonium nitrate is decomposed into nitrous oxide and water vapors.

Balanced chemical equation:

NH₄NO₃(s)   →   N₂O (g) + 2H₂O(g)

when it is rapidly heated it form N₂ and O₂.

2NH₄NO₃   →   2N₂ + O₂ + 4H₂O

By increasing the temperature decomposition is increased and in limited space due to pressure it may cause explosion.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
