Propane gas burns in air to form carbon dioxide and water.

Question

Propane gas burns in air to form carbon dioxide and water.

a) Write a balanced equation for the combustion of propane. Include phase designations.

b) How many grams of carbon dioxide and water will be formed when a mixture containing 3.907 g of propane and 10.848 g of oxygen is ignited?

Answer 1

C3H8(g) + 5O2(g) ---------> 3CO2(g) + 4H2O(g)

3.907g propane is 0.08moles

10.848 g of oxygen is 0.34 moles

propane will be finished so 3x0.08x44g of carbondioxide and 4x0.08x18 grams of water will be formed.
