Calculate the pressure that CCl4 will exert at 21°C if 1.00 mol occupies 18.2 L, assuming that CCl4 obeys the ideal-gas equation; CCl4 obeys the van der Waals equation. (Values for the van der Waals constants are given in this table.) (a) Assume CCl4 obeys the ideal-gas equation. atm (b) Assume CCl4 obeys the van der Waals equation. atm (c) Which would you expect to deviate more from ideal behavior under these conditions, Cl2 or CCl4? Explain.
HCl solution is added to 100. mL of buffer solution which is 0.10 M in NH3 and 0.1 M in Nh4Cl, what will be the pH of the new solution?
What state is being described in each case? Type either s for solid, l for liquid (make sure you type an l and not an i), and g for gas (assume ideal). If the statement applies to more than one state

Ammonia is produced by the reaction of hydrogen and nitrogen N2(g)+3H2(g)--->2NH3(g). a) How many moles of H2 are needed to react with 1.0 mol of N2? b) How many moles of N2 reacted if 0.60 mol of NH3 is produced?
A container with a removable partition contains gas A and gas B. Gas A is at 400K and 10.0 atm and gas B is at 400K and 4.00 atm. The partition is removed and the gases mix
The syringe used in this experiment is calibrated to 60 mL. However, there is a 'dead volume' at the needle end of the syringe that is uncalibrated. This volume equals 1.20 mL. Bearing in mind that the syringe is upside down
