1) Which of the following are true statements about nitric oxide?

Select all that apply:

• It is a stable molecule despite having an unpaired electron.
•  
• It easily forms a dimer, N2O2.
•  
• It is unusual because it contains a nitrogen-oxygen triple bond.
•  
• The nitrogen has two lone pairs of electrons.

2. Fluorine reacts readily with calcium to form calcium fluoride. In this product, the oxidation number of the calcium atom is +2

. What is the molecular formula for calcium fluoride?
