everthing clearly pls

Answer 9

Oh golly gee wiz! OK!! :D

Answer 10

ok i will wait

Answer 11

Chemical formula for Alumium oxide = \(\sf \color{red}{Al_2O_3}\)
to find molec mass, add up the mass of each element, which you can find on the periodic table or look up above, which they have already given you.

Since there is 2 alumniums, you multiply by 2, and three oxygens, multiply by three...
And, you have molar mass.

2(27) + 3(16)

Do the same for the others.

Answer 12

@abb0t can u do all pls it will be helpfull

Answer 13

I already explains how to work them. You can do the others yourself, or at least try. I have a hair appointment right now.
