how to balance this partial equation given below

Question

k2cr2o7+h2so4+kI-->k2so4+cr2(so4)3+h2o+I2

Answer 1

You CANNOT continue in chemistry and not use the caps key.
I will get you started.
Cr goes from +6 for each on the left to +3 on the right for each. I on the let is -1 and on the right is zero. Make things easy by making that 2KI on the left. You may need to change it later but if you don't start with that the equation never will balance.
