Answer:
The answer is K2SO4 + BaCl2 = BaSO4 + 2KCl
Explanation:
First, you can do it by looking how many chlorine is being used. As you can see that 2 chlorine is being used so you are sure that 2 chloine is in the right side.
Secondle, there are also 2 potassium in the left side so there must be also 2 potassium in the right side.
K2 + Cl2 = K2Cl2 (to make it beautiful)
= 2KCl (you can take out 2, just similar to factorisation)
(Hope this can help)
