In a reaction involving the iodination of acetone, the following reaction mixture was used: 5.00mL 4.0M acetone, 5.00mL 1.0 M HCl, 5.00mL 0.0050 M I2, and 10.0 mL water.  what was the molarity of the acetone in the reaction mixture? (Recall that M1V1=M2V2)   the color of the above reaction mixture disappeared in 250 seconds. What was the rate of the reaction?

Bromine monochloride is synthesized using the reaction Br₂(g) + Cl₂(g) = 2 BrCl(g) Кр = 1.1 x 10-4 at 150 K A 209.0 L flask initially contains 0.901 kg of Br₂ and 1.104 kg of Cl₂. Calculate the mass of BrCl, in grams, that is present in the reaction mixture at equilibrium. Assume ideal gas behavior. mass of BrCl: 6.0 g

5. A reaction is initiated by mixing suflur dioxide and oxygen. This reaction forms sulfur trioxide. 2 SO2 + O2 5 2 SO3 if we start the reaction with 0.100 M SO2 and 0.150 M O2, and allow the reaction to run until the concentration of SO3 is 0.020 M, what is the concentration of O2 and SO3 in the mixture at that point?

Can you help me figure out how to get to Answer A?  I've got 2 attachments - the question w/ correct answer and my work to show what I'm doing.

Triphenylmethanol LAB Q 4. Bubbling occures when HCl is added to the reaction mixture. What gas is produced?

0.1 gram of solid aluminum phosphate (Al(PO:) (s) is added to 500 L of pure water. Immediately the solid begins to dissolve according to the reactions below. Complete dissolution: Al(PO,) (s) → Al + PO, No K Solid present: Al(PO.) (s) + Al + PO, Ksp = 1012 %3D What is the concentration of dissolved phosphate (in M and mg/L) in the water once all reactions proceed to completion? Is the solid still present or has it completely dissolved? Why or why not? If the solid is present, calculate the solid concentration (in M and mg/L). Develop a plot showing the aqueous (dissolved) concentration of PO; (in M) on the Y-axis versus different AI(PO,)(5) additions (in M) on the X-axis. Include the critical point that separates whether the solid is completely dissolved or is still present and label your plot appropriately.
