If A, B, and C are sets, prove: (A - B) is a subset of C iff (A - C) is a subset of B.

I've already wasted hours on this problem (I hardly know where to start), so I would appreciate any help. Thank you!

"A student was titrating 15.0 mL of NaOH solution of unnknown concentration i a 100 mL beaker. After adding 17 mL of 0.01 M HCL, she realized she had forgotten to add the indicatior. She quickly added 2 drops of bromothymol blue indicatior and her solution went yellow immediately. What is the simplest procedure thi student can do to correct and finish her experimnt and not have to start over? Describe experimental procedures and mathematical analysis."

This is for my chem lab, and I'm not sure what to do. You could add more NaOH until the solution is neutralized, but that wouldn't tell you the concentration or even how much HCL you neutralized. Any ideas?

We all know about hair and eye colour combinations eg blonde hair and blue eyes, brown hair and hazel eyes, black hair and green eyes and so on and so on. The list is long. But is there a hair and eye colour combination that doesn't occur? a hair and eye colour which are not naturally seen together.

Natural colours please i don't want suggestions for white hair and purple eyes or some crap like that.

I touched some sponges on the beach yesterday and now my skin itches on every point where there was some contact. It has happened before and it took weeks to stop itching. Is there a way to make the skin expell the spicules faster, or at least to make it itch less?

A friend told me it was quicker to drive from york to london,due to some weird scientific theory. It had something to do with the fact that york is further north, so driving south was easier and quicker due to less of a gravitational pull. Is there any truth to this?
