How many grams of F2 must react with NaCl in the following reaction if 800 kJ of energy are released? 2NaCl + F2 --> 2NaF + Cl2, ?H = -320 kJ
A. 47.5B. 95.0C. 40.0D. 125E. 190
Calculate the distances NH3 gas and HCL gas would travel in this experiment if a 100.00-cm tube were used, based on the accepted molar masses of the two gases.
Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by 0.30
NH3 is a weak base (Kb=1.8 x 10^-5) and so the salt NH4Cl acts as a weak acid. What is the PH of a solution that is 0.039 M in NH4Cl?
Calculate the expansion work done in kJ against a constant external pressure of 0.961 atm and at a constant temperature of 20°C. Assume that the initial volume of dry ice is negligible and that CO2 behaves like an ideal gas.
Calculate the equilibrium constant for the following reaction at 298K and biological standard state: CH3CHO +NADH +H+ --> C2H5OH + NAD+ E° ?= -0.197V for the CH3CHO/ C2H5OH couple.
The dissolution of ammonium nitrate, NH4NO3, in water is an endothermic process. Since the calorimeter is not a perfect insulator, will the enthalpy of solution for ammonium nitrate be reported as too high or too low if this heat change is ignored..
