chemistry
a sample of hydrogen occupies a volume of 950 mL at -15.3 degrees celcius. if the temperature increased to 30.0 degrees celcius, what would be the new volume?

Chemistry
a sample of carbon dioxide has a volume of 25.0L at 5.80 x 10^2 mmHg. what pressure would be needed to increase the volume to 55.5 L? assume constant temperature

chemistry
If a 0.10 M solution of silver fluoride, AgF, is mixed with a 0.10 M solution of barium acetate, Ba(C2H3O2)2, a pecipitate (ppt.) forms: AgF + Ba(C2H3O2)2--> ppt. In order to identify the precipitating ions, you conduct some experimental tests. a) what is the purpose of thi...

chemistry
assume you had a solution that contained a mixture of a silver ions and stronium ions. come up with three different reaction plans that would allow you to precipitat either the silver ion or strontium ion, but the other ion would remain in solution

Chemistry
nevermind, figured it out!
