Write Lewis structures, including resonance structure and formal charges if necessary
Suppose that you developed your own new temperature scale, denoted oN. You chose 30.0oN as the temperature of freezing water and 280oN as the temperature of boiling water at 1.0 atm pressure.
In Breckenridge, Colorado, the typical atmospheric pressure is 514 torr. What is the boiling point of water (ΔHvap = 40.7 kJ/mol) in Breckenridge?
Why can a first nitration be done at 0 degrees Celsius but the ice bath is removed to complete the reaction in a dinitration
At equilibrium the total pressure was 1.00 atm and the NOCl prssure was 0.27 atm. 2NOCl(g) &hArr 2NO(g) + Cl2(g) Calculate the partial pressure of NO and Cl2 in the system
iF 0.80g of a gas occupies 295 mL at 25 degrees Celcius and 680 mm Hg of pressure, what is the molar mass of the gas.
a solution made by adding .106 mol of CH3COOH to 1.0 kg of water is found to freeze at -.203 C. Calculate the percent of the acid that has undergone ionization. The molal freezing point constant of water is 1.86
A solution is made by dissolving 15.5 grams of glucose (C6H12O6) in 245 grams of water. What is the freezing-point depression of the solvent if the freezing point constant is -1.86 °C/m?
How many grams of water are needed to react with 78.0g CaCN2? How many grams of NH3 are produced from 5.19g CaCN2?
A current is drawn from the cell until 2.20 g of silver have been deposited at the silver electrode. Calculate E for the cell at this stage of operation in volts.
Why is molarity not the best means of stating acid strength? Is molarity the most representative form of quantifying acids and bases?
Calculate the value of the activation energy for decomposation of NOCL?
An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 1281 nm and the second at 102.5 nm, to return to the ground state (n=1).
