$CH_4+O_2 \rightarrow CO_2+H_2O$First, start by balancing one of the elements. Let's try hydrogen first...$CH_4+O_2 \rightarrow CO_2+2H_2O$Then, check to see if that offsets any other elements. In this case, we need more oxygen atoms on the left side, so lets fix that next...$CH_4+2O_2 \rightarrow CO_2+2H_2O$Then we check to see if any other elements have been offset. In this case, it looks like all the elements are equal. It's balanced! I'll give you a jump start on the next one... $K_2O+H_2O \rightarrow KOH$First, try balancing the potassiums, and then we can see where you need to go from there.
