Chem Help Needed! Please?!?

what is the freezing point and normal boiling point of a solution made by adding 39 mL of acetone, C3H6O3 to 225 mL of water? The densities of acetone and water are 0.790 g/cm^3 and 1.00 g/cm^3, respectively.

Chemistry - Calculating concentration?

So we had a lab in class. We took a strip of aluminum (0.679 g) and placed it in 100 mL of lead(II) chloride solution. We left it like that for two days. Then there were lead particles that formed in the solution. We took the aluminum strip out, washed it in acetone and reweighted it (0.600 g). Our teacher gave us this balanced equation for the reaction: 2 Al(s) + 3 PbCl2(aq) --> 2 AlCl3(aq) + 3 Pb(s) . I need to calculate the concentration of [Pb^(2+) (aq)] and [Cl^(1-) (aq)]. How can I calculate this? I know C = n/V . Thanks.

Can type 1 Diabetes/hyperglycemia cause vomiting?

I had DKA and I took a sip of water and threw it up in 5 seconds, I threw up for 24 hours straight. It got so bad I was throwing up acid and burned my throat so bad I was in ICU for 5 days, I could not keep anything down. That didn't used to happen but as with everything you change over time, so the answer to your question is YES
