Question

write the balance equation for the reaction involving the combustion of Methane in Co2 to form carbon dioxide and water​

Answer 1

Answer:

Explanation:You know the reactants, methane and oxygen and you know the products, carbon dioxide and water. So write the equation and then balance it using the rules you were taught.

CH4+O2−−>CO2+H2O

you just need to figure out how many moles of each compound you need to that the numbers of each element is the same on the reactant and the product side.

There is one carbon in methane and one carbon in carbon dioxide so the number of moles of each must always be the same. let’s set that number at 1.

There are 4 moles of H in methane but only 2 moles of H in water so you need two waters for every one methane. so now there are 2 moles of water because we decided there is only 1 mole of methane (and carbon dioxide)

1CH4+xO2−−>1CO2+2H2O

Then add up the oxygen atoms in the methane, carbon dioxide and water and figure out how many oxygen molecules you need to get that number of O atoms. that will be the value you put where I wrote x.
