Ok guys here are some more questions please i want them answered by tommorow morning very important for me?

I think that you have to spend some time learning the very basics. There are no chemical symbols such as NaC1 , CaC12 and A1. If you do not understand enough chemistry so that you substitute the numeral 1 in place of the lower case l in chloride (Cl) aluminium (Al) and you write C12 (that is 12 atoms of carbon) when you mean Cl2 (that is 2 atoms of chlorine) then you should not be doing problems of this sort, you should be studying more basic chemistry.
