Answer 1

Man fail..

How many atoms are in \(2 Al_{3}O _{2}\)

Answer 2

So this is kinda like math, such that, you distribute the coefficient across each atom in the formula and you multiply it by the subscript.

\(\sf 2(3~Al+2~O)=6~Al+4~O\)

Answer 3

O that should be \(10\) @AARONQ

Answer 4

YUP 100%

Answer 5

Whew 3rd one right e-e

Answer 6

what about this one?

\(\sf 3~Ca(OH)2\)

Answer 7

wait 2 is subscript. \(\sf 3~Ca(OH)_2\)

Answer 8

wait you want me to solve this also? D:

Answer 9

yes

Answer 10

>:D for practice

Answer 11

So \(5\) atoms?

Answer 12

\(\sf 3(1~Ca+2~O+2~H)=3~Ca+6~O+6~H\)

Answer 13

R.i.p I don't understand.

Answer 14

the 2 on the outside of the bracket multiplies the whole bracket.

These formulas make more sense when you draw them
