Can someone please help me with some steps towards solving this problem? A glass tumbler containing 243.3cubic centimeters of air at 1.00e2kPa (barometric pressure) and 20Celsius is turned upsde down and immerse in a body of water to a depth o 20.5m. The air in the glass is co...

thank you I finally got it

HERE IS MY HOMEWORK: I have been trying the real gases homework for hours and am completely stuck. This is what I have been attempting to make work. First I found the moles then plugged in all the other variables. 100gC2H2/26.0373g/mol=3.84mol C2H2=n P=nRT/(V-nb)-an^2/V^2 P= n...

Thank You, you are absolutely correct!

20.0mls of a bulk solution was transferred to a 100ml volumetric flask and diluted to volume with water. 2.00mls of this solution was then found to have a concentration of 0.15M. What is the concentration of the bulk solution. McVc=MdVd (Mc)(.02L)=.15M(.002L) Mc= .015M concent...

Chemistry
Why .10L

Chemistry
Can some one check to see if I did this correct: 6M= moles of solute/.005 L solution .03=moles solute M of2nd solu=.03 m solute/.05L solution M=.6

I am hoping to receive help getting started with this problem, possibly some steps in the correct direction. Here is the question: 5.0mLs of a 6.0M solution of HCl was transferred to a 1000ml volumetric flask and diluted to volume w/ water. 50mLs of this solution was then tran...

Chemistry Conductivity
In my homework the teacher asks for us to use conductivity variables and explain why whole milk would have a different conductivity then skim milk. He really does not give us the information or on any math to back this up so to me it seems the answer is obvious that skim milk ...

Chemistry Redox Reaction
Balance the equation as a redox reaction in acidic solution. Cu(s)+NO3^-1(aq)-->Cu^2+(aq)+NO(g)

I guess getting started is the hard part for me here, I figured out that sodium phosphate adn barium chloride are the reactant and look like this NaH2PO4+BaCl2--> But then I do not know how to convert to a ionic equation or what the product would be??

Chemistry 101
Write the reaction that occurs when sodium phosphate and barium chloride react. Be sure to include the phase labels. Then write the total ionic reaction and the net ionic reaction including proper phase labels.

Chemistry
I really appreciate the help, I understand all the concepts I just get overwhelmed with all the steps sometimes, when I see all those numbers and letters, This just saved me hours of confusing myself even further if I did not have any help.

This is what I keep trying and am not coming up with the answer that he gave us (.43grams) Homework: KIO3- is 1.005g/214amu=.00469 .00469x1/3=.00156 .00156x380.7=.593 grams (I amu x 3=380.7) Is there something I am doing wrong with my math or is the teachers answer of .43 inco...
