Answer quickly, will give 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 | starting amount of sicl4 | starting amount of o2 | actual yield of sio2
1 | 120 g | 240 g | 38.2 g
2 | 75 g | 50 g | 25.2 g
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 reaction.
