when methane, ch4, is combusted, it produces carbon dioxide, co2, according to the unbalanced equation: ch4 + o2 → co2 + h2o.

write the balanced equation for this reaction, and explain how it is possible for 10 grams of methane fuel to burn and emit 27 grams of carbon dioxide. discuss whether or not this reaction obeys the law of conservation of mass.

Hi again :)

Sorry I couldnt help ya yesterday but Im going to try and help you now

Balanced equation for this is

CH4 + 202 > c02+ 2h20

The law of conservation of mass states that after a reaction the mass stays the same.

It has to obey because everything does or it is improper

Using Avogadro MOLES formula one mole is 6.02 x 10^23

(Im sorry I cant draw a mole table on here)

You have to work out the mass from the moles

We know that mass = Mr  x moles

Using this formula we can calculate the atomic number and Mr

There is one mole so the mass numbers correspond accordingly

it is H2O-CO2>CH4+02  I will help u out more

the correct answer is 2 and 4
