Answer: CS2 + 3 O2 = CO2 + 2 SO2
Step-by-step explanation:
There is an extra sulfur atom on the left side of the equation, so put a coefficient of 2 in front of SO2 on the right to balance it out. That results in 6 oxygen atoms on the right, so balance the left side by adding a coefficient of 3 in front of O2, so there are 6 oxygen atoms on both sides.
