An engineer is designing a new tank to hold hydrogen gas for use in an experimental vehicle’s fuel system.
The tank is to be made out of a special metal alloy that is much less dense than steel. The engineer needs to know whether or not the alloy will be strong enough
to hold a sufficient quantity of hydrogen under pressure. The specifications call for 1.20 x 10^3 L of hydrogen at normal atmospheric pressure, 101 kPa to be compressed into a 40.0 L tank made of light alloy. The alloy can readily withstand pressures up to
5050 kPa. Assuming constant temperature, calculate the pressure that will exist in a filled tank. Predict whether the alloy will be able to hold the hydrogen safely.

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.
