Two newly discovered compounds, Pandemonium and Cascadium, are put into an isolated system with each other. Initially, the Pandemonium is at 90.3 ºC and the Cascadium is at 20.6 ºC, but they are allowed to achieve thermal equilibrium with each other. The Pandemonium sample has a mass that is 4.7x larger than the mass of the Cascadium sample.

Pandemonium has a molar heat capacity that is 2.1x smaller than the molar heat capacity of Cascadium.

John thinks the Pandemonium will undergo a smaller change in temperature than the Cascadium. Is the statement true? If so, why is it correct? If not, explain why it is wrong.

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

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.
