So far q(rxn) = q(water) + q(CaCl2) (136g)(4.184J/°Cg)(Tfinal - 25.0°C) = (125g)(4.184)(Tfinal - 25.0°c) + (11g)c(Tfinal - 25.0°C).
The specific heat capacity is measured in J/(kg K) or J/(kg °C), and it is the amount of heat (J) absorbed per unit mass (kg) of the material when its temperature rises by 1 K (or 1 °C).The average kinetic energy of the atoms or molecules in the system is measured by temperatures. The zeroth law of thermodynamics states that when two objects are in thermal equilibrium, no heat is transferred between them, resulting in an equalisation of their temperatures.
