The initial pH of chloroacetic acid is 1.90, (which I found from using the quadratic equation to find x in a RICE table because I was given the initial concentration of 0.124M and told to find the pH of a 10.0 mL solution.). You titrate the solution with a 0.100 M NaOH. Predict the volume of NaOH required to reach the equivalence point.
to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
Equilibrium constant (Kc) is 1 and inital concentrations of A and B are Cao and zero (Cbo = 0), respectively. Da is equal 2 for each reactor in series configuration. What is the overall conversion of A for above equilibrium reaction?
How many grams of ammonium sulfate are needed to make 0.3500 L solution at a concentration of 5.000M.
A balloon filled with H2(g) at STP has a volume of 2.24 .What is the final gas volume if 0.10 mol He(g) is added to the balloon and the temperature is then raised to 92.0 celsius while the pressure and amount of gas are held constant?
A 74.0-mL sample of 0.13 M HNO2 (Ka = 4.0 × 10-4) is titrated with 0.14 M NaOH. What is the pH after 25.8 mL of NaOH has been added?
Have you observed that when you spill water over your skin on a hot day it will cool you down but if you spill vegetable oil in place of water it will not cool you down give explanation for this difference?
What is the percent yield of ammonia when 150.0 g of nitrogen reacts with 32.1 g of hydrogen if the actual yield is 174 grams?
what happens if cellulose is reacted with maleic anhydride C4H2O3? Again, how is the cellulose molecule/structure altered and what are the reaction by-products?
During a refueling outage, workers discover black, soft material in the reactor core (obviously a Foreign Materials Exclusion Area breech). To help identify the breech source, you are asked to determine the material
Phosphoric acid is a weak triprotic acid with the formula H3PO4. If you have 50.0 mL of a 1.0 M solution of H3PO4, how many grams of NaOH (MM = 40.0g/mol) should you add to make a buffer with a pH of 7.00?
256 grams of sodium chloride reacts with an excess of calcium oxide. How many grams of sodium oxide are produced?
What is the expected freezing point of an aqueous solution of 2.62 kg of nitric acid, HNO3 , in a solution with a total mass of 5.91 kg? Assume that the nitric acid is completely ionized.
