A sample of gas is held at constant pressure. If the number of moles of this sample of gas is halved and the absolute temperature of this sample of gas is doubled what happens to the volume of the gas? Select one
a. The volume is doubled
b. The volume is halved
c The volume is quadrupled
d. The volume is quartered
o
e The volume stays the same.

Design techniques and materials that reduce the negative environmental impact of a structure are referred to as

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
