3 0

Answer:

it is option 2.

Explanation:

when balancing equations, both sides need to have the same number of the element.

4As + 3O2 - -> 2As2O3

4 as. 4 as (2×2=4)

6 o (because 3×2=6) 6 o (2×3=6)

since there are the same amount of each element on both sides, the equation is balanced.

hope this helps:)
