A sample of 44.0g of solid NaCl is dissolved in 50.0g of water at 28.C. NaCl(s)Na(aq)+Cl(aq)H=+3.9kJ/molrxn What is the final temperature of the solution? C5 (solution) =4.184J/gK A 25.0mL solution of HCl is mixed with 25.0mL of NaOH. The concentrations of both solutions before mixing is 1.63M. Initially both solutions are at 23C. This acid base neutralization reaction occurs. What is the final temperature of HCH(aq)NaOHH2O(l)+NaCl(aq)H=57.9kJ/molrxn Cs (solution) =4.184J/gK Assume 1mL of solution has a mass of 1g
