Question

Do we need to write the states ie. solid liqid or gas below the compounds in chemical equations in class 10 board exams?​

Answer 1

Yes we need to write..
But compulsory if the question is from Chapter 1st i.e
Chemical reations and equations !!

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

Yes, it is important to show physical states of reactants and products in chemical equation.

$\bold{\boxed{Reasons }}$

1. While writing a chemical equation, gaseous, liquid and solid states are symbolised as (g), (l), and (s) respectively.

2. This is done to make it more informative and to emphasise that those reactions occur in that manner only under those conditions.

Hence, physical states of reactants and products are mentioned while writing a chemical equation.

Hope it helps!
