In order for a hydrogen atom to be capable of hydrogen bonding, what is required?
describe the observations you would make and write a net ionic equation for any reaction that would occur.
A solution of sulfuric acid is prepared by mixing 66.7 mL of 18.0 M sulfuric acid with 233.3 mL of 1.50 M sulfuric acid, and diluting with water to the total volume of 500 mL. What is the molarity of the final solution
Calculate the quantity of work associated with the compression of gas from 5.60 L to 3.40 L at a constant pressure of 1.23 atm.
How many milliliters of 0.100 mol of KOH solution are needed to completely neutralize the HCl in 300 mL of a hydrochloric acid solution that has a pH of 2.25?
Which solvent gave the fastest reaction; ethanol, or the ethanol/acetone mixture? Explain how the solvent affects the rate in the SN1 reaction.
If 3 moles of NaCl are needed to produce 1 mole of AlCl3, how many grams of NaCl are needed to produce 200 grams of AlCl3? Show all of your work/calculations.
Benzoic acid precipitated when the aqueous solution of sodium benzoate in beaker A was acidified. If benzoic acid failed to precipitate after acidification, how would you recover benzoic acid from beaker A
The boiling points of HCl and CO2 are nearly the same (-85 degrees C and -78 degrees C). Explain why CO2 can be removed from an aqueous solution by boiling briefly while essentially no HCl is lost even after boiling for one hour or more
prepare 10 ml of solution that represents a 4 fold dilution of the stock solution
find the density of a substance with a mass of 51.2g and a volume of
A solution of 0.10 M sodium acetate is mixed with a solution of 0.10 M acetic acid (Ka = 1.8*10^-5). When equal volumes of the two solutions are mixed together the resulting mixed has a pH of:
The density of water is 1.00 g/ml and the density of propanol C3H8O is 0.866 g/ml. What volume of propanol contains the same number of molecules are present in 127.1ml of water
