Balance the equation: C3H8+O2=CO2+H2O? + Example - Socratic
2018年3月7日 · C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O We have: C_3H_8 + O_2 -> CO_2 + H_2O I would always start by balancing the elements that only occur once on each side. In this case it's carbon. We also notice that as it now stands we have an odd number of oxygen molecules on the right and an even number on the left, which won't work. We can fix this by multiplying the water by an even number. C_3H_8 + O_2 -> CO ...
