B. increase, increase, decreasing
C. increase, decrease, increasing
D. decrease, increase, increasing

Answer 2

I believe it's C, but not 100% positive?

Answer 3

It's D

Answer 4

Just like when you add salt to water in winter. The salt (the nonvolatile solute), lowers the freezing point of water so it doesn't freeze until much lower temperature. It also raises boiling point because the NaCl ions have more interacting bonding with the water molecules, so it takes more energy to free the H2O molecules to boil. The more salt you put in (increased molarity) the more effective the salt is at doing this

Answer 5

I hope this was helpful

Answer 6

Ohhhhh okay, got it! Thank you so so much!
