Balancing equations help watch

1. If H= 4 to make 4HCL then CL= should be 8 not 9?
So is it 8 or 9? If its 8 could you tell me why?

PS.. the equation in the picture is not balanced out yet

2. Anyone?

The balanced equation would be:

CH4 + 4CL2 -- CCl4 + 4HCL

Reactants: C=1, H=4, Cl=8
Products: C=1, H=4, Cl=8
4. The balanced equation for this is :
CH4 + 4Cl2 = CCl4 + 4HCl
Carbon - 1 Carbon - 1
Hydrogen - 4 Hydrogen - 4
Chlorine - 8 Chlorine - 8

Since the number of elements are equal on both sides the equation is balanced.

CL = 8 because the "4" on the second half of the equation "4HCl" doesn't just mean that hydrogen is 4, it means that everything behind it is times by 4 and since in the first part of the second half of the equation we have CCl4 we have another 4 chlorine so when we add them together we get 8. On the first part of the equation we see : 4Cl2. since we have another 4 in front of the element we times the whole thing by 4, and since we have two chlorine's (Cl2) we times the two chlorine's by four meaning that we have 8 chlorine's on that side also which makes the equation balanced.

Hope this makes sense !! x

Yes it did make sense, thanks so much!
