# Balancing chemical equations: CuSCN & KIO3

Chemistry Level 2

$\ce{ a \, CuSCN + b \, KlO_3 + c \, HCl -> d \, CuSO_4 + e \, KCl + f \, HCN + g \, ICl + h \, H_2 O }$

Balance the chemical equation above, where $$a$$ to $$h$$ are positive integers. What is the smallest value of $$a+b+c+d+e+f+g+h$$?

Hint: You may want to use simultaneous linear equations if you are stuck.
