1. What volume of 0.10 M NaOH is needed to neutralize 100 mL of 0.050 M HCl? 2a. When 100 mL of 0.01 M NaOH solution is mixed with 100 mL of 0.01 M of HNO3 solution, what is the concentration of H+ and the pH in the resulting mixture? 2b. When 100 mL of 0.01 M NaOH solution is mixed with 100 mL of 0.02 M of HCl solution, what is the concentration of H+ and the pH in...
When a chemist mixed 3.33 g of LiOH and 255 mL of 0.62 M HCl in a constant-pressure calorimeter, the final temperature of the mixture was 23.4°C. Both the HCl and LiOH had the same initial temperature, 20.4°C. The equation for this neutralization reaction is: LiOH(s) + HCl(aq) → LiCl(aq) + H2O(l). Given that the density of each solution is 1.00 g/mL and the specific heat of the final solution is 4.1801 J/g·K, calculate the enthalpy change for this reaction...
