Answer:
Both compound types have oppositely charged regions.
Explanation:
i took the test.
so the answers would be:
1. solvent
2. Water molecules will attract each other electrically, but they will not attract oil molecules, causing separation.
3. Yes, it can be extracted through evaporation. It retains its original properties.
4. The water would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
5.oxygen
6. The number of particles of solute in a solution is measured in moles.
7. Both compound types have oppositely charged regions.
8. oppositely charged ends
9. It easily dissociates into ions in solution.
10. 11.0
11. HCl, H2S, PH3
12. Sulfur (S) has a larger atomic size than oxygen (O), so HS– is a more stable, weaker base than OH–.
13. 4
14. The negative log of the concentration of OH– ions is 2. Sodium hydroxide is a strong base.
15. A solution of potassium hydroxide will always have a lesser concentration of solute than a solution of ammonia.
(the rest are typed out answers, so just give them your best shots.)
