Has a standard free-energy change of -4.00 kJ/mol at 25 °C. What are the concentrations of A, B, and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively
A solution contains 0.010 M each Cu(NO3)2 and Bi(NO3)3. An equal portion of 12 M NH3 is added to the solution. What is the initial concentration of OH- (in M) once the two solutions have been mixed together, but prior to any reactions occurring? Th..
When 0.0200 mol gaseous NH3 and 0.0180 mol gaseous O2 are placed in a 1.00 L container at a certain temperature, the N2 concentration at equilibrium is 2.20Ã-10-3 M. Calculate Keq for the reaction at this temperature.
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
nitroglycerin C3H5(NO3)3 detonates into N2, O2, CO2, and H2O. In addition 6.26 kJ of heat is given off per gram of nitroglycerine denotated. what is the specific heat when 4.65 g of N2 is formed
Erythrocytes phosphorylate glucose to glucose 6-phosphate with the help of the enzyme hexokinase instead of glucokinase. Hexokinase has a Km = 0.04 mM.
Classify the substances CaCl2, CuSO4, NH3, C2H5OH according to the strongest solute-solvent interaction that will occur between the given substances and water during dissolution from the following choices
Write the complete molecular formula and then completes ionic equations. Then write the net ionic equation.
At the start of the experiment, both thermometers record the same temperature. Why does, after 10 min, thermometer B record a lower temperature than thermometer A?
Write balanced reactions for the complete combustion of each fuel and use standerd enthalpies of formation to calculate the amount of heat relesed per kilogram pf the fuel.
Imagine you are working on ways to improve the process by which iron ore containing Fe2O3 is converted into iron: Fe2O3(s) + 3 CO(g) 2 Fe(s) + 3 CO2(g)
on't 2 and 3 have multiple answers? I think I'm only supposed to have one, though? How do you differentiate using the water solubility chart?
Calculate the number of grams of AlCl3 and the number of grams of H2O formed when 0.500 g of Al(OH)3 reacts.
