Question

what component of a chemical reaction is highlighted in red? fe₂o₃(s) + 6hcl(aq) → 2fecl₃(aq) + 3h₂o(l) states of matter yields subscripts products

Explanation:

The red - highlighted parts in the chemical reaction ($\text{Fe}_2\text{O}_3$, $\text{HCl}$, $\text{FeCl}_3$, $\text{H}_2\text{O}$) are the subscripts. Subscripts in a chemical formula indicate the number of atoms of the preceding element. For example, in $\text{Fe}_2\text{O}_3$, the subscript 2 indicates 2 iron atoms and the subscript 3 indicates 3 oxygen atoms.

Answer:

subscripts
