Question 1

Calculate the lattice energy for MgO(s) using a Born-Haber cycle and the following information:

MgO(s) → Mg2+(g) + O2-(g)?
Mg(s) → Mg(g)+147.1 kJ/mol
Mg(g) → Mg+(g) + e-+737.8 kJ/mol
Mg+(g) → Mg2+(g) + e-+1451 kJ/mol
1/2 O2(g) → O(g)+249.0 kJ/mol
O(g) + e- → O-(g)-141.1 kJ/mol
O-(g) + e- → O2-(g)+798.0 kJ/mol
Mg(s) + 1/2 O2(g) → MgO(s)-601.8 kJ/mol

◦ +3844 kJ/mol
◦ +2444 kJ/mol
◦ +4108 kJ/mol
◦ +1842 kJ/mol

Question 2

Calculate the energy change in kJ/mol for the reaction using the following information:

Li(g) → Li+(g) + e-+520 kJ/mol
F(g) + e- → F-(g)-328 kJ/mol

◦ +848 kJ/mol
◦ -192 kJ/mol
◦ -848 kJ/mol
◦ +192 kJ/mol

Once thought to have neurofibromatosis, Joseph Merrick (also known as "the elephant man") is now, in retrospect, thought by clinical experts to have had Proteus syndrome. This endocrine disease causes continued and abnormal growth of the bones, muscles, skin, and so on and can become completely debilitating with severe deformities occurring anywhere on the body.

Did you know?

Though the United States has largely rejected the metric system, it is used for currency, as in 100 pennies = 1 dollar. Previously, the British currency system was used, with measurements such as 12 pence to the shilling, and 20 shillings to the pound.

Did you know?

The tallest man ever known was Robert Wadlow, an American, who reached the height of 8 feet 11 inches. He died at age 26 years from an infection caused by the immense weight of his body (491 pounds) and the stress on his leg bones and muscles.

Did you know?

One way to reduce acid reflux is to lose two or three pounds. Most people lose weight in the belly area first when they increase exercise, meaning that heartburn can be reduced quickly by this method.
