Help pls In the following reaction, oxygen is the excess reactant.
SiCl4+O2=SiO2+Cl2
The table shows an experiment record for the above reaction
Trial 1 :starting amount of SiCl4 150g starting amount of O2 200g actual yield of SiO2 49.2g
Trial 2: starting amount of SiCl4 75g Starting amount of O2 50g actual yield of SiO2 25.2
Calculate the percentage yield for SiO2 for trial 1 also determine the leftover reactant for the trial show your work
Based on the percentage yield in trial 2 explain what ratio of reactants is more effective for the given reaction

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
