Question 1

The correct mathematical expression for finding the molar solubility (s) of Sn(OH)2 is:

◦ 2s2 = Ksp

◦ 2s3 = Ksp

◦ 108s5 = Ksp

◦ 4s3 = Ksp

◦ 8s3 = Ksp


Question 2

The following questions refer to the following system: 500.0 mL of 0.020 M Mn(NO3)2are mixed with 1.0 L of 1.0 M Na2C2O4. The oxalate ion, C2O4, acts as a ligand to form a complex ion with the Mn2+ion with a coordination number of two.

 

What is the equilibrium constant for the following formation?

Mn2++ 2C2O42–

[Mn(C2O4)2]2–

 
Mn2+ + C2O42– MnC2O4
 
K1 = 7.9 × 103
 
[Mn(C2O4)2]2– MnC2O4 + C2O42–
 
K2 = 1.26 × 10–2
 
Reference: Ref 16-2

​

​


◦ 1.0
◦ 3.7 × 102
◦ 2.1 × 10–1
◦ 6.3 × 105
◦ None of these are correct.

Elderly adults are living longer, and causes of death are shifting. At the same time, autopsy rates are at or near their lowest in history.

Did you know?

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
