Answer :
Final answer:
Percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100. To determine the percent yield of oxygen and carbon dioxide in the pyrotechnician's experiment, the theoretical yields of these gases would be needed, which are not provided in the question. The theoretical yield could be influenced by many factors, including the initial quantities of reactants and specific reaction conditions.
Explanation:
Percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying the result by 100. In this case, the pyrotechnician doesn't provide the theoretical yields of oxygen and carbon dioxide, which makes it impossible to calculate the percent yield directly.
Based on stoichiometric calculations in the provided equations, the reaction involves methane and oxygen, producing carbon dioxide and water. Each methane molecule reacts with 2 oxygen to yield a carbon dioxide and 2 water molecules.
However, without more specific information about the initial quantities of reactants or the specific conditions of the reaction, it's impossible to calculate the theoretical yield and thus the percent yield. For example, if there were a surplus of one reactant, that could influence how much of each gas is produced. Also, real-world factors such as reaction inefficiencies and incomplete reactions could affect the actual yields in unpredictable ways.
