Curious Carl lost the results of his chemistry lab on reaction rates. He and his partner added crushed antacid tablets to four solvents in 50 ml beakers. The temperatures of the solvents are displayed in the chart. Using your knowledge of kinetics and reaction rates, see if you can help Carl out and organize his data: 12 seconds, 45 seconds, 15 seconds, 32 seconds. How would you fill in the reaction time data, from top to bottom, in Carl's data table?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
