Gaseous methane (CH4) reacts with gaseous oxygen (O2) gas to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of carbon dioxide formed from the reaction of 1.28 g of methane and 10.1 g of oxygen gas? Be sure your answer has the correct number of significant digits in it.

Theoretical yield of is 3.51 g.

Explanation:

Balanced equation:

Molar mass of = 16.04 g/mol

Molar mass of = 32.00 g/mol

So, 1.28 g of = of = 0.0798 mol of

10.1 g of = of = 0.316 mol of

According to balanced equation-

1 mol of produces 1 mol of

So, 0.0798 mol of produce 0.0798 mol of

2 moles of produce 1 mol of

So, 0.316 mol of produce 0.158 mol of

As least number of moles of are produced from therefore is the limiting reagent.

So, theoretical yield of = 0.0798 mol

Molar mass of = 44.01 g/mol

So, theoretical yield of =
