Chemistry balancing skeleton equations

studiot

Personally if the author of the original equation thought to include something, I would not take it out.

so I would leave the (g) in in this case.

If the original equations was simply

$$\displaystyle {H_2} + C{l_2} \to 2HCl$$

That would also be OK, and is a very common way of reporting it.

What I meant is that I have to show how I got to that answer.

There are two hydrogen (H) atoms on the reactants side and two chlorine (CI) atoms on the reactants side. One hydrogen (H) atom and one chlorine (CI) atom is produced. To balance them, we put a coefficient of 2 in front of the product hydrogen chloride (HCI).
Does this work?
