A 4.4-mL sample of a 0.14 M HCl(aq) solution was mixed with a 6.3-mL sample of a 0.68 M HCl(aq) solution. Calculate the pH of the mixture. Provide your answer to the correct number of decimal places. Your Answer: Answer Hide hint for Question 16 There is no reaction. You are simply mixing two solutions of the same acid. First calculate the molarity of the mixture and finally the pH of the mixture.
Question 8 (2 points) A 6.5-ml sample of a 0.11 M HCl(aq) solution was mixed with a 4.1-mL sample of a 0.70 M HCl(aq) solution. Calculate the pH of the mixture. Provide your answer to the correct number of decimal places. Your Answer: Answer Hide hint for Question 8 There is no reaction. You are simply mixing two solutions of the same acid. First calculate the molarity of the mixture and finally the pH of the mixture.
if 22.0 mL of water containing 0.030 mol of HCl is mixed with 38.0 mL of water containing 0.030 mol of NaOH in a calorimeter such that the initial tempature of each solution was 27.0 degrees C and the final temperature of the mixture is 35.0 degrees C, how much heat (in kJ) is realeased in the reaction? Assume that the densities of the solutions are 1.00 g/mL.
