b) 2
c) 6
d) 9

during chemistry lab, mrs. black’s students placed an antacid tablet in a zip lock bag. they recorded the mass of the tablet in the bag. then they carefully added 50 grams of water and quickly sealed the bag. the tablet began to fizz and soon disappeared. the bag was filled with gas and it felt cold to the touch.
what type of change occurred in the bag and how can you support your answer?
a) it is a physical change because the tablet dissolved.
b) it is a physical change as evidenced by change in temperature.
c) it is a chemical change due to the change in temperature and gas production.
eliminate
d) it is a chemical change because the tablet dissolved and the temperature of the liquid dropped.

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.
