đĨ BRAAI CHEMISTRY CHALLENGE! đĨŠâī¸
When you light up that gas braai for the weekend, propane (CâHâ) burns in oxygen to produce carbon dioxide and water.
Your Challenge:
Write the balanced chemical equation for this reaction
If you burn 2.2 kg of propane, how many kg of COâ are produced?
How many litres of oxygen (at STP) are needed for this reaction?
Given:
Molar masses: C = 12 g/mol, H = 1 g/mol, O = 16 g/mol
At STP: 1 mole of gas = 22.4 L
