The rate constant for the second- order reaction.starting with a concentration of 0.86m, calculate the concentration of NOBr after 57s.
A 20.00mL sample of H3Y was titrated with 0.1000 M NaOH. The first equivalence point was reached after the addition of 14.98mL of base. The second equivalence point was reached after the addition of 30.03mL.
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.
Rank the enthalpy of solution from most exothermic to most endothermic. To rank items as equivalent, overlap them.
175g pure H2O was placed in a constant-pressure calorimeter and chilled to 10C 9.8g pure H2SO4 (also 10C) was added, stirred and the temperature rose to 19.8C.
