Question

If 7.00g of CH2 is burned in excess Oxygen, what number of moles is formed with H2O

Answer 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

Answer 2

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

Answer 3

Perhaps intended CH4.

Answer 4

THANKS!!!!
