A 64.3-g piece of aluminum at 94 °C was immersed into 70.0-g water at 25.0 °C. The water temperature rose to 36.4 °C. Calculate the molar heat capacity of the metal.
The bond energies increase in the order: O2^1
A tank containing carbon dioxide at 400K and 50 bar is vented until the temperature in the tank falls to 300K. Assuming there is no heat transfer between the gas and the tank
Explain the general physics of chromatography. Illustrate these general principles with regard to paper, thin layer, gas, liquid, and super-critical fluid column and open tube chromatography.
Show all long pair electionrs (this means even those unreactive lone pairs), proper mechanistic arrows, all intermediate steps, and all side reactions if any. If you write them by hand please write clearly so I can understand everything.
It has a pressure of 46.3 mmHg and 24.6 C (degrees). what is the molecular formula og the compound
At standard temperature and pressure (0 C and 1.00 atm ), 1.00 mol of an ideal gas occupies a volume of 22.4 L . What volume would the same amount of gas occupy at the same pressure and 35 C ? Express your answer numerically in liters.
if 4.50g of methane gas is introduced into an evacuated 2.00 L container at 35 celcuis what is the pressure in the container?
What is the final temperature of a mixture of that 5.00 x 102 mL of hot water at 95.0°C and 475 g of -12.0°C ice cubes? (NOTE that in this process, the ice heats up to its melting point, melts, and then heats to the final temperature of the mixtur..
At 300. K and 1.20 atm, assume that 30. mL of NO gas reacts with 25 mL of oxygen gas and excess water to produce gaseous nitric acid according to the following equation:
entropies of atom combination to determine if any of the following reactions have an equilibrium constant greater than 1. Find the reaction with the greatest equilibrium constant. Find the reaction with the smallest equilibrium constant.
In N2O, nitrogen is the central atom and the oxygen atom is terminal. In OF2, however, oxygen is the central atom.Use formal charges to explain why.
The pressure of a sample of gas at 10.0 C increases from 700. mm Hg to 900. mm Hg. What is the new temperature?
