WILL MARK BRAINLIEST In the following reaction. oxygen is the excess reactant: SiCl4 + O2 -> SiO2 + Cl2.
The table shows an experimental record for the above reaction:
Trial 1: Starting amount of SiCl4 is 150g, Starting amount of O2 is 200g, and actual yield of SiO2 is 49.2g.
Trial 2: Starting SiCl4 is 75g, O2 is 50g, and actual yield of SiO2 is 25.2g.
A: Calculate the percentage yield for SiO2 for trial 1. Also determine the leftover reactant for the trial. Show your work.
B: Based on the percentage yield in trial 2, explain what ratio of reactants is more efficient for the given reason.
