Question

chemistry

Answer 1

i got 1 and 1.4 so is it Cr2O2 @vocaloid

Answer 2

you got your mole ratio down to 1 mol Cr and (approximately) 1.4 or 1.5 mol O, right?

1.4 or 1.5 are too far away from a whole number, so we multiply both by 2 to get 2Cr: 3O

Answer 3

if you have 0.5, or 1.5, etc. you would multiply by 2

if you have like 0.25 or 1.25, etc. you would multiply by 4

the idea is to get it to the closest whole number
