0.030 moles of a weak acid, HA, was dissolved in 2.0 L of water to form a solution. At equilibrium, the concentration of HA was found to be 0.013 M. Determine the value of Ka for the weak acid. 1 2 NEXT Based on the given values, fill in the ICE table to determine concentrations of all reactants and products. HA(aq) H:O(1) H:O“(aq) A-(aq) + + Initial (M) 0.015 Change (M) -X +x +x Equilibrium (M) 0.015 - x +x +x

Use ICE table, solve Ka, and the pH based off table/Ka. Show all work, thank you!

Using the letters on the image, identify each component of the titration set-up. Buret clamped to a ring stand with a beaker underneath. The letter A appears at the top of the buret, the letter B appears midway down the buret, the letter C appears at the bottom of the buret, the letter D appears next to the beaker, and the letter E appears on the other side of the buret, near the ring stand.

Second time asking, first answer was not correct, please give correct answer this time,

1. The [H30"], in M, of 10.00 mL of 0.100 M NAOH after adding 10.00 mL of indicator solution. To enter exponential values, use the format 1.0e-5. Answer: 2. The [H30"], in M, of 10.00 mL of 0.100 M HCl after adding 10.00 mL of the indicator solution. To enter exponential values, use the format 1.0e-5. Answer:

Incorrect Row 2: Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. Calculate the solubility at 25 °C of AgCl in pure water and in 0.34 M NaCN. You'll probably find some useful data in the ALEKS Data resource. Round your answer to 2 significant digits. Solubility in pure water: Solubility in 0.34 M NaCN: 1.3 × 10™³M ☐ x10 OM ☑
