Iwhen performing the experiment for magnesium oxide :

Why is the empty crucible and cover fired to heat?

How critical are the suggested times for heating and cooling?

How can you tell when the magnesium metal has reacted cmpletely?

How cn you tell when the copper wire has reacted compleely?

What are the major sources of experimental error?

A) Without doing any calculations (just compare the correct K_sp values) complete the following statements:

B) For each of the salts on the left, match the salts on the right that can be compared directly, using K_sp values, to estimate solubilities. If more than one answer is correct, enter the letters without delimiting characters.

Write the expression for K_sp in terms of the solubility, s, for each salt, when dissolved in water.

Note: Multiply out any number and put it first in the K_sp expression. Combine all exponents for s.

C) Determine the relative solubilities of the following magnesium compounds:

Ka for hypochlorous acid, HClO, is 3.0x10-8.Calculate the pH after 10.0, 20.0, 30.0, and 40.0 mL of 0.100MNaOH have been added to 40.0 mL of 0.100 M HClO. I am mostly confused on when 40.0 mL is added, because that will be the equivalence point I believe.

Determine the heats of formation or the steric energies of the exo- and endo-anhydride adducts using a molecular mechanics program. What do these energies tell you about the mechanism of the reaction?

The rate constant for the reaction:

2A -> 2B + C

is 0.881M^-1*s^-1 at 333 degrees Celcius.

(a) Starting with a concentration of 0.0955 M, calculate the concentration of A after 12.5 seconds.

(b) Calculate the half-live when [A] = 0.0444 M.

Calculate the amount of solution (g or mL) that contains each of the following amounts of solute.

5.2 g of LiNO3 from a 35 %(m/m) LiNO3 solution.

31.6 g of KOH from a 20.0 %(m/m) KOH solution.

3.1 mL of formic acid from a 18 %(v/v) formic acid solution.

Thermodynamics of potassium nitrate dissolving in water experiment post-lab questions: What does the sign of the delta G tell you about the dissolution process for this experiment? Is the dissolution process spontaneous at all temperature? If not at what temperature does this spontaneity change?

Why does the Doppler effect lead to a shift in the atomic emission frequencies of hydrogen atoms in a star but a broadening of the atomic emission frequencies of hydrogen atoms in a gas?

When the following equation is balanced properly under acidic conditions, what are the coefficients of the species shown? 2 Fe + MnO4- 2 Fe2+ + Mn2+ Water appears in the balanced equation as a product (reactant, product, neither) with a coefficient of 2 . (Enter 0 for neither.) How many electrons are transferred in this reaction?

Describe briefly (4-6 sentences) what factors are responsible for influencing what face of a π-system in a chiral environment a reagent will attack from.

If the hydrolysis to the diacid is not complete, how could you separate the desired diacid from the unhydrolyzed anhydride by extraction?

You carry out a reaction starting with 200 mg of cyclopentadiene and 300 mg of maleic anhydride and 375 mg of the cycloadduct anhydride is obtained. Calculate the % yield for the anhydride. Show your calculation.
