  1. mol of CH2 = 12+2 = 14 grams
    so
    7/14 = .5 mol of CH3

    equation
    2CH2 + 3O2 --> 2CO2 + 2H2O
    so for every mole of CH2 we get one mole of water and one mole of CO2
    so the result is .5 mole CO2 and .5 mole H2O

  2. I wonder about CH2. What is it? It could be the empirical formula for C2H4 which is ethylene (now named ethene).

  3. Perhaps intended CH4.
