Question

Hydrogen gas (H2) and chlorine gas (Cl2) react to form hydrochloric acid (HCl). What is the
correct balanced chemical equation for this reaction?

Answer 1

H\(_2\) + Cl\(_2\) \(\rightarrow\) HCl
now you tell me, is that balanced?

Answer 2

No...?

Answer 3

Lol. Is it or is it not? I'm asking you.

Answer 4

xD lol. I think no...

Answer 5

Correct. It is not. You have 2 hydrogen atoms and 2 chlorine atoms on the product side (right). And you only have 1 hydrogen and 1 chlorine atom on reactant side (left). So, now you need to balance it by doing what?

Answer 6

;-; That's the part where i have no idea.................

Answer 7

Add a number in front of HCl.
the point of balancing is to show you that what you start with does not just magically disappear! If you have 4 molecules total going in, you must also have 4 coming out.

Answer 8

If you are making a sandwich with cheese and ham, you have bread + cheese + ham = sandwich,
the sandwich is composed of 3 things. but the cheese did not just disappear. its still there.

Does that make sense?

Answer 9

xD yeah that makes sense.
Thanks for helping me c:
I got it now~

Answer 10

So you would put a \(\sf \color{red}{2}\) HCl
to get: \(\sf \color{blue}{H_2 + Cl_2 \rightarrow 2 HCl}\)

Answer 11

the 2 tells you that you have 2 HCl = 1 H + 1 Cl and 1 H and 1 Cl. and you still have two hydrogens and two chlorines. Nothing disappeared.

Answer 12

it B. i'm taking the same thing lol and thank you~
