Answer:
Zn + H2SO4 ZnSO4 + H2
Explanation:
Start by balancing the equation. This one is already balanced.
(1 zinc, 2 hydrogen, 1 sulfur and, 4 oxygen on each side of the equation).
The mole ratio just refers to the coefficient (the number before each molecule or atom). Since there are no numbers in this equation all coefficients are 1.
Mole ratio = 1:1
