Aliquid mixture containing 40.0 wt% n-octane and the balance n-decane flows into a tank mounted on a balance. the mass in kg indicated by the scale is plotted against time. the data fall on a kg) and = 10 min; m 250 kg) straight line that passes through the points (t 3 min; m 150 |(q5.1a) estimate the volumetric flow rate (l/min) of the liquid mixture. in the pixar film, up, carl fredrickson turns his house into a makeshift airship using helium balloons. (q5.17a) neglecting the force required to remove the house from its foundation, how many spherical balloons, each having a 9.5- inch diameter and an interior gas pressure of 1.05 atm, would carl have to tie to his house for it to float? assume that the house weighs 1.00x105 lbf , and that atmospheric pressure and temperature are 1.0 atm and 25 c

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.
