Question 1: The average human requires 120.0 g of glucose (C6H12O6) per day. How many grams of CO2 (in the photosynthesis reaction) are required in order to produce this amount of glucose?

The photosynthesis reaction is: 6CO2+6H2O→C6H12O6+6O2

Question 2: Molten iron and carbon monoxide are produced in a blast furnace by the reaction of iron (III) oxide and coke (pure carbon). If 25.0 mol of pure Fe2O3 is used, how many grams of iron can be produced? The reaction is:  Fe2O3 + 3 C → 2 Fe + 3 CO

Question 3: Bauxite ore contains aluminium oxide, which is decomposed using electricity to produce aluminium metal. How many moles of aluminium metal can be produced if 100 g of oxygen is released?

Question 4: Determine the mass of oxygen required to completely burn 10.0 g of propane (C3H8).

Question 5: Predict the mass of hydrogen gas produced when 2.73 g of aluminium reacts in a single replacement reaction with excess sulphuric acid
