Three (3) brine solutions B1, B2, and B3 are mixed. B1 is one-half of this mixture (one-half of mixture mass, not volume). Brine B1 is 2.5% salt, B2 is 4.5% salt and B3 is 5.5% salt. To this mixture is added 35 lbm of dry salt, while 230 lbm of water is evaporated leaving 3200 lbm of 5.1% brine. Determine the amounts (in lbm) of B1, B2, and B3.

Which orbitals form a pi bond? a.the s orbital and three p orbitals b.the s orbital and two p orbitals c.overlapping p orbitals d.overlapping hybrid orbitals

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

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.
