A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, acetone, glycerol, tetrahydrofuran, and ethanolamine,
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection
of Material Safety Data Sheets (MSDS), the chemist finds the following information:
liquid
density
carbon tetrachloride 1.6g. cm
ole
acetone
0,79 g" C11
glycerol
1.3 g cm
tetrahydrofuran
13
(0,89 g • CHI
ethanolamine
1.0 g. cm
Next, the chemist measures the volume of the unknown liquid as 0.781 L and the mass of the unknown liquid as 617. g.

What stress will shift the following equilibrium system to the left? n2(g) + 3h2(g) ⇌ 2nh3(g) adding more n2(g) adding more nh3(g) increasing the pressure of the system reducing the volume of the container

If i add water to oil what will happen

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.
