Read each question carefully and calculate the theoretical yield for the given chemical reactions. Show all your work and include appropriate units.
1. In the reaction of hydrogen gas with oxygen gas to produce water, if you start with 10.0 grams of hydrogen (H₂) and excess oxygen (O₂), what is the theoretical yield of water (H₂O) in grams?
2. The theoretical yield is the amount of product that can be formed from a given amount of reactants, assuming the reaction goes to 100% completion. It is calculated using principles.
3. Consider the combustion of methane (CH₄): CH₄ + 2O₂ → CO₂ + 2H₂O. If 16.0 grams of methane reacts with 64.0 grams of oxygen, determine the theoretical yield of carbon dioxide (CO₂) in grams.
4. The actual yield is always greater than or equal to the theoretical yield.
True
False
5. What information is NOT directly needed to calculate the theoretical yield?
Balanced chemical equation
Molar masses of reactants and products
Initial mass of limiting reactant
Experimental conditions (temperature, pressure)
