Answer 11
7 (Neutral)Slide24
Question 12
A new substance is found. You decide to see if it dissolves in water. You find that the substance clumps up and does not dissolve. What can you conclude about the polarity of this substance?Slide25
Answer 12
This substance is non-polar! “Likes dissolve likes”Slide26
