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

Did you know?

In 1864, the first barbiturate (barbituric acid) was synthesized.

Did you know?

Atropine, along with scopolamine and hyoscyamine, is found in the Datura stramonium plant, which gives hallucinogenic effects and is also known as locoweed.

Did you know?

If all the neurons in the human body were lined up, they would stretch more than 600 miles.

Did you know?

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

Did you know?

Blood in the urine can be a sign of a kidney stone, glomerulonephritis, or other kidney problems.
