Question

What will happen when excess chlorine gas is reacted with ammonia gas?

Answer 1

As we know that in chemistry, equations play a major role. In the reaction three things are main. There are reactants, products and reaction conditions. The reactants are always on the left side of the equation. If more than one reactant in the equation means by using plus sign. The products are always on the right side of the reaction. Something here also follows. More than one product by using plus sign. In between reactant products are used arrows to find the reaction direction in the equation.

Complete answer:
We need to know that ammonia reacts with excess chlorine to give hydrochloric acid and nitrogen trichloride. The nitrogen trichloride gives yellow explosive liquid.
If excess ammonia added means the product will be ammonium chloride.
The molecule formula of ammonia is
The chemical equation for the above discussion is given below,
$N{H_3} + 3C{l_2} \to NC{l_3} + 3HCl$
According to the above discussion, we conclude when excess chlorine gas is reacted with ammonia gas to give hydrochloric acid and nitrogen trichloride.

Note:
In balanced chemical reaction wise, we predict the side product of the reaction. In some cases we are not able to attain the balance by changing the mole. In that case we use the number of countable ions in the product and reactant side of the chemical reaction. In chemistry, redox reaction is one of the types of major reactions. In this redox reaction two methods are used to attain the balanced chemical reaction. There are ion-electron methods and the oxidation number method.
