How would you balance the following equation: H2 + O2 --> H2O?
2015年11月10日 · "2H"_2("g)" + "O"_2("g")rarr"2H"_2"O(g)" "H"_2("g)" + "O"_2("g")rarr"H"_2"O(g)" At first glance, the H atoms appear to be balanced, but the O atoms are not. There are two O atoms on the left side and one on the right. Place a coefficient of 2 in front of "H"_2"O" on the right side. "H"_2("g)" + "O"_2("g")rarr"2H"_2"O(g)" Now the O atoms are balanced, but the H atoms are no longer balanced ...
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 ...
