Calculate how many grams of aluminum oxide (Al2O3) can be produced from 10 grams of aluminum reacting with excess oxygen (4Al + 3O2 → 2Al2O3).
💡 Hint: Use molar masses to convert grams to moles.
If a reaction yields only 80% of the expected amount, how does this impact the stoichiometry you've calculated? Calculate the expected yield from 50g of CH4 if the complete combustion yields 112.3g of H2O.
💡 Hint: Calculate the percentage yield based on stoichiometric calculations.
