When 9.55 g sample of solid sodium hydroxide dissolves in 100.0 gof water in a coffee-cup calorimeter, the temperature rises from23.60 ºC to 47.40 ºC. Assume that the specific heat of the solutionis the same as that of pure water. Calculate the ?H in kJ/mol NaOHfor the solution process: (please show work)
NaOH (s) ? Na+ (aq) + OHâ (aq)
AND.. Write a balanced chemical equation for the combustion ofpropane gas (C3H8). C3H8 + 5O2 ---> 3CO2 + 4H2O
