What is the final temperature in degree C when 8.70 grams of Lithium sulfate are dissolved in 60.00 grams of H2O? Report the temperature to the tenths of a degree.

Heat of solution for Lithium sulfate is - 29.8 kJ / mole. (negative 29.8)

The initial temperature of the water and the Lithium sulfate are both 25.0 oC.

Assume the specific heat of the solution is the same as the specific heat of pure water.

Assume no heat is lost or gained from the surroundings.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
