Question

Which equation has both a liquid and a gas as products? 2 upper H g upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g). 2 upper M g (s) plus upper O subscript 2 (g) right arrow 2 upper M g upper O (s). 1 UJpper K upper C l upper O subscript 3 (s) right arrow 2 upper K upper C l (s) plus 3 upper O subscript 2 (g). Upper M g (s) plus 2 upper H upper C l (a q) right arrow upper H subscript 2 (g) plus upper M g upper C l subscript 2 (a q).

Answer 1

Let us predict the gas and liquid products in option

Explanation:

option  1 :  2 upper H g upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g).

Chemical reaction

It is the reactants react to form products .

Chemical equation

It is the method of representing reaction in terms of moles , specifying states , symbols , molecular formulas etc .

This actually gives the complete info about the reaction .

In the above asked question or any other question we can specify the states by writting :

Solid as "S".

Liquid as "L"

Gas as (g).

Answer 2
