Is density of an organic molecule directly related to the molecular weight of a substance. (That is, does density always increase when molecular weight increases) Use the examples above to explain.
In the reaction below, 4.86 atm each of H2 and Cl2 were placed into a 1.00 L flask and allowed to react: H2(g) + Cl2(g) 2 HCl(g) Given that Kc = 89.9, calculate the equilibrium pressure of HCl.
Choose the answer which presents the chemical formulas for two substances in order of decreasing melting point (highest melting point first) and gives a valid reason for this order.

ichromate solution is 0.0189 M dichromate, and it took 26.01 mL of your standard iron solution to titrate the excess dichromate in an unknown. What is the chemical oxygen demand of the sample, in units of mg O2/L?
Under what conditions would you expect a real gas to be (a) more compressible than an ideal gas; (b) less compressible than an ideal gas
How many milliliters of 6 M HNO3 would you add to 300 mL of the buffers solution to change the pH from 5.09 to 5.03?
Concentrations of aerosol constituents are sometimes expressed as ppb (mole fraction) to enable comparison with gaseous concentrations expressed in ppb. The unit ppb (mole fraction) is evaluated as RT x concentration of aerosol constituent in nano..
