i really need help on this!!?

Question

when methane (CH4) gas is burned in the presence of oxygen, the following chemical reaction occurs.

CH4 + 2 O2 -----> CO2 + 2 H2O

If 1 mole of methane reacts with 2 moles of oxygen, then

a) 6.02 x 10 ^23 molecules of CO2 and 6.02 x 10 ^23 molecules of H2O are produced
b) 1.2 x 10 ^24 molecules of CO2 and 1.2 x 10 ^24 molecules of H2O are produced
c) 6.02 x 10 ^24 molecules of CO2 and 1.2 x 10 ^24 molecules of H20 are produced
d) 1.2 x 10 ^24 molecules of CO2 and 6.02 x 10 ^23 molecules of H2O are produced

please explain

Answer 1

its really not that difficult.

for every 1 mole of methane and 2 moles of oxygen that are together (using the coefficients each reagent)

then 1 mole of carbon dioxide (CO2) and 2 moles of water are produced.

since the question asks if 1 mole of methane reacts with 2 moles of oxygen, then all you have to do is find the answer with the same ratio of products---- 1 CO2 : 2 H2O

Answer 2

Knowledge of Avogadro's Number and mole ratios will tell you that c is the correct answer.

Answer 3

Use the Pythagoream Theorom of Chemicals.

Answer 4

correct answer is C
but dude, it's not cool to make someone else do your homework

Answer 5

Is this your homework i it is you should not be asking this question!!!!!!!!!!!!!!!!!!
