Answer:

↓

Explanation:

I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.

Hopefully that makes sense! :)
