7. C : Dinitrogen Tetrafluoride
8. A : Phosphorus pentachloride<em />
9. C : Metallic <em>(<!> This is the only one I'm not 100% sure of)</em>

12. B : Covalent
Answer:
The answer is the second picture.
Explanation:
Answer:
The concentration is 0.036 mg/mL
Explanation:
Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL
Here are my reasonable beliefs
For number 1. what the answer seems to be is C.Than looking are numbers two and three their answers are both B
My reasoning for them is , because if you think about the solid liquid gas's this is a common result in most experiments.also for number two , you have to decrease ( go down ) on the concentration ( hardness ) of the subject to get a more powerful solution
So far as number one , for it to be water the atoms have to be far away from the other moving freely , to be a solid they can barely move at all.
