Calculation of Enthalpy of Reaction Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ ...
It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=m(soln)cΔT =75.0 x 4.184 x (27.21-25) =693.5J =0.6935kJ q(rxn)= -0.6935kJ ΔH=-0.6935kJ I also struggle...
