1. A student investigates the enthalpy of solution, AH coln, for two alkali metal halides, LiCl and NaCl. In addition
to the salts, the student has access to a calorimeter, a balance with a precision of +0.1 g, and a thermometer with
a precision of +0.1°C.
(a) To measure ΔΗ,
Isoln for LiCl, the student adds 100.0 g of water initially at 15.0°C to a calorimeter and adds
10.0 g of LiCl(s), stirring to dissolve. After the LiCl dissolves completely, the maximum temperature
reached by the solution is 35.6°C.
(i) Calculate the magnitude of the heat absorbed by the solution during the dissolution process, assuming
that the specific heat capacity of the solution is 4.18 J/(g•°C). Include units with your answer.
(ii) Determine the value of AH soln for Lici in kJ/mol. com

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
