How many moles of methane occupy a volume of 2000 mL at 50 degrees Celcius and 746 torr?
Plutonium-240 (PU-240) is a byproduct of the nuclear reaction that takes place in a reactor. It takes one thousand years for 10% of a 4.60 g sample to decay. (Nuclear decays are first-order reactions)
The pre-exponential factor for the gas-phase decomposition of ozone (unimolecular reaction) is 2.3x1013 L mol-1 s-1, and the experimental activation energy is 30.0 kJ mol-1. What is (a) the entropy, (b) the enthalpy and (c) the Gibbs free energy o..
why is it dangerous to heat a liquid in a distilling apparatus that is closed tightly at every joint and has no vent to the atmosphere?
During the saponification of ethyl tetradecanoate, would you expect the product to generate foam/froth when mixed
When the substance is dissolved in a 1.20x10-3 M solution of HA, the catalyzed rate constant was found to be 3.20x10-5. Calculate the dissociation constant, Ka, of HA.
(a) When 1.50 mol of Al and 3.00 mol of Cl2 combine in reaction 2 Al(s) + 3 Cl2(g) -----> 2 AlCl3(s), which is the limiting reactant. (b) How many moles of AlCl3 are formed. (c) How many moles of the excess reactant remain at the end of the reacti..
The decomposition of HI(g) is represented by the equation 2HI(g) H2(g) + I2(g) Kc= 64 at 25°C. If the equilibrium concentrations of H2 and I2 at 400°C are found to be [H2] = 9.3x10-4 M and [I2] = 1.6x10-3 M, what is the equilibrium concentration o..
Propanoic acid, HC3H5O2, ionizes in water. A 0.496 g sample of sodium propanoate, NaC3H5O2 (molar mass: 96.07 g/mole) is added to a 50.0 mL sample of a 0.265 M solution of propanoic acid. Assuming that no change in the volume of the solution occur..
If the enthalpy change for the reaction is 20 kJ/mol and the entropy change is 50 J/mol/K, the conversion of reactants to products is spontaneous above 400 K.
Hydrolysis of an ester using sodium hydroxide (2M) is usually a fast reaction. Why would it take almost 40 minutes to complete? It is imperative to consider the location of each reagent within the vial.
A 50 mL sample of 0.10 M HCl is mixed with 100 mL of 0.20M NH3. What is the resulting pH? (Kb for NH3 = 1.8 x 10-5).
The measured cell voltage is 0.0841 V and the Pt | H2 | H+ half-cell is the cathode. Standard reduction potentials are given on the next page. (a) Draw a diagram of the electrochemical cell, labeling all electrodes and solutions. (b) What is the p..
