4fe + 302 > 2fe2o2

Answer 1

What is your question?

Answer 2

which one is coefficients & owhich one is subscrpts

Answer 3

\(\color{red}4~Fe + \color{red}3~O_2 \rightarrow \color{red}2~Fe_2O_2\)

the coefficients are highlighted in red.

just so you know, coefficients are always at the front of the chemical formula.

Answer 4

thank youu

Answer 5

do you know which one is subscript?

Answer 6

the subscripts are the little numbers at the bottom, like \(\large O_{\color{red}2}\)

Answer 7

thanks (:

Answer 8

you're welcome !

Answer 9

___h2 + ___o2 > h2o do you know how to balance that ?

Answer 10

I do now how to balance it, but you should try it yourself because it's a basic step for other chemistry related question (you will effectively have to do if you're taking chemistry).

use a calculator if you need to
