You removed a Coke can from the refrigerator. When you come back a few minutes later, you realize the can has begun to "sweat". In other words, moisture forms on the outside of the can. Select ALL of the statements that describe the formation of condensation
on the can.
)
A)
Water vapor in the air gains energy, causing it to form condensation on the
can
B)
As water molecules in the air come in contact with the cold can, they will
slow down.
C)
As water molecules in the warm air collide with the cold can, they will lose
energy and become colder.
D)
Vapor molecules in the air are attracted to water molecules on the can
causing them to bind to the can.
E)
Condensation on the can comes from water vapor in the air cooling and
slowing and becoming liquid on the outside of the can

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, a + b → ab. single-displacement double-displacement synthesis decomposition

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.
