a. Epimers and diastereomers

b. Aldoses and ketoses

c. Alpha (α) anomer and beta (β) anomer

d. D glucose and L glucose

80g of glucose dissolve in 1 liter of solution what is the molarity of solution

How much 0.113 M NaOHM NaOH solution will completely neutralize 1.25 LL of 0.228 M HCIM HCl solution?

Consider one mole of H2O(g) which occupies 20 L at 1 atm. Condensation of H2O(g) at releases 30.22 kJ/mol of heat to the surrounding. Given that the density of H2O(l) at 373 K is 0.925 g/cm3 , calculate the change in the internal energy for the condensation of one mole of water at 1 atm and 373 K. 

Calcium oxide is commonly known as line,crystallizes in a typical sodium chloride structure.

1.Draw a unit cell of MC as calcium oxide structure.

2.Confirm the stoichiometry of the formula of calcium oxide if consistent with the rock Salt.

3.What is the coordination number of the anion and cation in the structures??.

4.Construct a born-haber cycle for the formation of calcium oxide.Do not perform any calculation. Label all the required thermodynamic processes with a diagram and provide definitions for all the terms used and indicate which are exothermic/endothermic.

Hydrolysis of C7H6Cl2 was carried out by refluxing with excess KOH solution. The resulting solution was acidified with dilute HNO3 and excess AgNO3 added to precipitate the chloride ions as silver Chloride, 0.718g of AgCl was formed from 0.805g of C7H6Cl2. (a) calculate the number of chloride atoms present in each molecules of C7H6Cl2? (b) Suggest an explanation for the result obtained in (a)? (c) Give a possible structure of C7H6Cl2?
