Determine how many kgs of methane (CH 4 ) are in completely insulated piston with the given properties: Pressure = 3 bar absolute. Volume = 2 cubic meters.
How much energy is required to boil 45.5g of water at 100 degrees C at sea level? The molar heat of vaporization of water is 40.6 kJ/mol.
A mixture of 4.50 g of He, 12.0 g of Ne, and 29.0 g of Kr is placed in a cylinder at STP. Calculate the partial pressure of each gas.
How many liters of ammonia gas can be formed from the reaction of 150 L of hydrogen gas? Assume that there is complete reaction of hydrogen gas with nitrogen gas and that all measurements are made at the same temperature and pressure.
Find molarity, molality, percentage composition, boiling and freezing point of a solution - What are the boiling and freezing points of the solution?
Once the pKw's at the three temperatures are determined, the Van't Hoff equation can be used to determine Delta H for the reaction, and from that Delta G, and Delta S can be calculated.
