For question 1B, could anyone explain why the change in number of moles in 2 when the equation is
CH4 + 2O2 -----> 2H20 + Co2

Well the change in gas actually negative 2. That's because there's 3 moles of gas on the left side and 1 mole of gas on the right side. Also if you're confused, water is a liquid in this reaction and not a gas because it says the temperature is constant at 25 degrees celsius.
