A weak acid dissociates in pure water according to the equilibrium
HACAU + H200 H30+20 + A 9
1. The weak acid, HA, has an acid dissociation constant, Ka=7.2999999999999998x107, is added to
water at a concentration of 0.51000000000000001M. (construct an ICE chart to assist)

a. What is the H30+ concentration in solution?
HAW + H201) + H30+4 + Acam

b. Describe how and why the addition of highly concentrated (not affecting solution volume) HCI
will affect the A- concentration. Justify your answer.

The pressure inside a hydrogen-filled container was 2.10 atm at 21 ? c. what would the pressure be if the container was heated to 92 ? c ?

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
