Chapter review questions: 2. Giv
EX
1. Define the terms solute and solvent giving one example for each.
2. Of the ones above that are soluble, write the chemical equations to show what
happens when they dissolve in water. An example is shown below:
EXAMPLE: aluminum sulfate
Al,(502), is soluble. (Sulfates are soluble except for Ba?, Sr, Pbe and
H9,2. Since AB+ is not one of the exceptions, aluminum sulfate must be soluble
3. Differentiate between saturated, unsaturated and supersaturated solutions
4. What mass of solute will dissolve in 100mL of water at the following
temperatures? Determine which of the three substances is most soluble in
water at 15°C
a) KNO, at 70°C
b) NaCl at 100°C
c) NH, Cl at 90°C
how does the phrase like dissolves like relate to solutions? ?​

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.

What type of interaction occurs between the r groups of valine and isoleucine in a tertiary structure? view available hint(s) what type of interaction occurs between the r groups of valine and isoleucine in a tertiary structure? salt bridge disulfide bridge hydrogen bond hydrophobic interaction
