What is the [h3o+] in a buffer that consists of 0. 30 m hcooh and 0. 20 m hcoona? for hcooh, ka = 1. 7 × 10−4.

The answer is : v = 55 + 8m plug in m = 25 v = 55 + 8(25) = 255 25 minutes after baxter begins filling the tank, the volume of water in the tank will be 255 gallons. slope: m = 8 gal/min for every min the water is on, the volume of water in the tank increases by 55 gallons. y-intercept: 55 (0,55) the initial volume of water in the tank was 55 gallons.

Ibelieve the correct answer is c
