Some ice cubes at 0 degrees celsius with a total mass of 335 g. are placed in a microwave and subjected to 750. W of energy for 5 minutes. (Assume all the energy of the microwave is absorbed by the water and no heat loss by the water) What is the final temperature of the water?
Draw the mechanism for each reaction you will do today. Pyridinium tribromide releases molecular bromine, so molecular bromine is the brominating agent.
What is the mass of one mole of the gas when the density of a gas is 0.0151 g/mL at 150 degrees Celsius and 1.50 atmospheres?
At 20 degrees C, the vapor pressure of ethanol is 45 torr and the vapor pressure of methanol is 92 torr. What is the vapor pressure at 20 degrees C of a solution by mixing 27.0 g of methanol and 75.0 g of ethanol?
Draw graphs representing Boyle's law, Charles's law, and Gay-Lussac's law for a fixed amount of gas. Make sure that you label each axis and state the assumptions for each law-that is, the variable(s) that is (are) held constant for each law.
Determine what given process is occurring when the color appears in the flame and an electron emits energy and it makes a transition to a higher energy orbital.
What is the minimum mass of each reactant necessary to produce 200 g of sulfuric acid in nthe following reaction?
A reaction mixture initially contains 2.8M H2O and 2.6 M SO2. Determine the equilibrium concentration of H2S if Kc for the reaction at this temperature is 1.3 x 10^-6 ?
What reagent could be used to reduce both the nitro and ketone functional groups in a single reaction?
Suppose a mercury thermometer contains 3.450 of mercury and has a capillary that is 0.180 in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0C to 25.0 C? The density of mercury at these temperatures is..
Determine the molar mass of the nonelectrolyte if the osmotic pressure of the solution = 23.6 atm, also express your answerin g/mol?
A flask contains 0.180 mol of liquid bromine, Br_2. Determine the number of bromine molecules present in the flask.
