A 496-mL sample of a gas at 263 oC is cooled at constant pressure until its volume becomes 241 mL. What is the new temperature in oC?
Differ from the ideal pressure? The value For N 2 gas is given as , a = 1.390 L2atm/mol2 and b = 3.910E-2 L/mol.
C2H4 + 3O2 = 2CO2 + 2H2O if 6.0 mol of co2 are produced, how many moles of o2 were reacted.
A 250.0 ml sample of gaseous hydrogen bromide, measured at 22.9 C and 0.930 atm, was dissolved in sufficient pure water to form 250.0 ml of solution. What was the pH of that solution.
Petroleum consumption in the US in 1990 supplied about 34.6E15 kJ of energy. Of this quantity, about 14.3E15 kJ was supplied by foreign sources.
What is the volume of Ammonia gas is dissolved in 40.0 mL of 15.0 M NH 3 solution at STP and Determine what is the vapor pressure of a solution made by dissolving 65.4grams ammonia in 259 grams of H 2 O at 55.0 ºC?
