Hurry pls I'll give the right answer brainliest 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

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
