Question

Fill in the coefficients that will balance the following reaction a0h2so4 + a1koh → a2k2so4 + a3hoh

Answer 1

a0 = 1
a1 = 2
a2 = 1
a3 = 2

This can be solved by guessing and checking and making sure that all atoms on the left side are accounted for on the right side. Both sides must have the same amount of atoms or the balancing is not correct.

Answer 2

a0h2so4 + a1koh → a2k2so4 + a3hoh

The balanced chemical reaction is:

H2SO4 + 2KOH → K2SO4 + 2H2O

hence,

a0 = 1

a1 = 2

a2 = 1

a3 = 2
