Besides water, what liquid can be used to safely dissolve granular chlorine? Also, is there anything which can be used to thicken the solution, to the point of something just like stick deodorant?
A 1g sample of carbon obtain from material found in a ancient site gave 7900 carbon-14 disentegrations in a 20-hour period. In the same amount of time 1g of carbon from a source found yesterday under went 18,400 disintegrations.
It is filled with helium at 23 oC and 0.991 atm and placed in an oil bath. To what temperature (oC) will the oil bath need to be heated to first open the safety valve?
In lab we vaporized a sample of acetone and measured the volume change of ice that was formed during the vaporization of the sample. This volume change was 0.29 mL. calculate the heat of vaporization
a high school girl was getting ready for a big date but discovered with horror that her silver necklace was tarnished.
A pyranose with the hydroxyl group on the anomeric carbon pointing up in the Haworth structure is designated
O2 gas is held over a container of water. If the total pressure of the gas mixture is 10.2 atm, what is the concentration of dissolved He in the water?
Compare the molar solubility of AgOH in pure water, with that in a solution buffered at pH 7.00. Note the difference between the two cases: when AgOH is dissolved in pure water, the pH does not remain at 7. The value of Ksp for AgOH is 1.5x10^-8 a..
at combustion temperatures the equilibrium constant for thereaction of n2 with o2 is about 10-14. calculate
Problem- A gas mixture is made by combining 7.0 g each of Ar, Ne, and an unknown diatomic gas. At STP, the mixture occupies a volume of 16.60. What is the molar mass of the unknown gas
