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.

What would be the original temperature of a gas that has a volume of 2.0 l and a pressure of 2.0 atm and an unknown temperature that the volume increased to 3.5 l in its pressure decreased to 1.0 atm if the final temperature is measured to be 11°c

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
