Потому что нужно чтобы и с левой и с правой стороны уравнения было одинаковое количество атомов каждого элемента. В CS2 - 2 атома серы, а в  SO2 всего один, для этого нужно взять две молекулы последнего, чтобы уравнялось. С О2 приблизительно такая же ситуация, но там арифметики чуть больше. И на будущее, когда ставят коэффициенты, считают, что все сошлось именно когда О с обеих сторон одинаковое количество.
