18. $zn + h_2so_4 \to$
19. $fe + cuso_4 \to$
20. $cl_2 + mgi_2 \to$

Explanation:

Step1: Check reactivity, predict products

For each reaction, use the activity series: a more reactive element replaces a less reactive one in a compound.

Step2: Balance the chemical equation

Adjust coefficients to equalize atom counts on both sides. If no reaction (less reactive element can't replace a more reactive one), write NR.
