7. A 27.8 L balloon is filled with 7.52g of gas X and placed next to a 27.8 L balloon filled with helium.
Given that Helium has a density of 0.179g/L, which statement correctly explains the movement of the balloons
with valid justification?
a) The balloon filled with helium will float higher because helium is less dense than gas X
b) The balloon filled with gas X will float higher because gas X is less dense than helium
c) Both balloons will float to the same level because their densities are the same
d) Both balloons will float to the same level because their volumes are the same
e) There is not enough information to determine the movement of the balloons

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.
