If 495g NaOH is dissolved in a final volume of 20.0 L, what is the molarity of the solution?
Determine the mole fraction of HO2CCH2CHOHCO2H in this solution?
Compute the concentrations of all species in a 0.900 M sodium sulfite solution. If it is given that the ionization constants for H2SO3 are Ka1=1.4x10^-2 and Ka2=6.3x10^-8.
Assuming all gases are at the same pressure and temperature, how many liters of CO2 are formed from 15.0L of CO.
For each reaction, calculate the mass (in grams) of the product formed when 10.1g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant.
What is the molar heat of vaporiza-tion of C6H6 if the vapor pressure of C6H6 is 120 torr at 27 degree celsius, and its normal boiling point is 80.1 degree celcius.
From the heats of reaction as given 3O2(g) ---> 2O3(g) DH = +284.6 kJ, 2H2(g) + O2(g) ---> 2H2O(g) DH = -483.6 kJ
Explain Cyclopentadiene reacts as a diene in the the Diels-Alder reaction a great deal faster than does 1,3 butadiene.
mixture(O,H) is ignited with a spark and it reacts to form (H2O)liquid water. determine the temperature of water.
