(a)
Interpretation:
To determine the balanced equation for the given reaction - When solid ammonium nitrite is heated, it produces nitrogen gas and water vapour.
Concept Introduction:
The balanced chemical equation is the equation in which number of different atoms of elements in the reactant side is equal to products side.
(b)
Interpretation:
To determine the balanced equation for the given reaction - Gaseous nitrogen monoxide (common name, nitric oxide) decomposes to produce dinitrogen monoxide gas (common name, nitrous oxide) and nitrogen dioxide gas.
Concept Introduction:
It is required that one can determine the reactants and products of the given statement and their respective states and write the unbalanced equation first. Then, balance it and determine the balanced equation. The balanced chemical equation is the equation in which number of different atoms of elements in the reactant side is equal to products side.
(c)
Interpretation:
To determine the balanced equation for the given reaction - Liquid nitric acid decomposes to reddish-brown nitrogen dioxide gas, liquid water, and oxygen gas (This is why bottles of nitric acid become yellow upon standing).
