3.Of the incubated 37 C sucrose samples, which solutions contained reducing sugars, you must include evidence to support your answers? 4. Which reaction condition was the most effective at hydrolyzing sucrose? Provide evidence to support this answer.

The solutions listed below were mixed to carry out the iodination of acetone. If the reaction took 168 seconds to finish, then what was the average rate (in M/s) for the iodination reaction? 5.0 mL of 3.0 M acetone 5.0 mL of 1.2 M HCl solution 10.0 mL of 0.0060 M 1₂ solution 5.0 mL of DI H₂O

please help with this question. it's not an assay, but calculation. thanks

What is the numerical value of Ke for the reaction if the concentrations at equilibrium are [SO2] = 0.15 M , [O2] = 0.16 M, and [SO3] = 0.50 M ? Express your answer using two significant figures.

Observations and Interpretations    NH4Cl(s) + H2O(l)          NH4+(aq) + Cl-(aq)   3) What did you observe when you placed this test tube in the boiling water bath?    4) Based on your observations in 3, which of the reactions in the equilibrium, written above, is endothermic and which is exothermic? Explain.    5) What temperature change did you observe when ammonium chloride was dissolved in water?              6) What does such a temperature change indicate, and is this consistent with what you observed in 3? Explain.  ANSWER ALL QUESTIONS!!!

Silver chloride (MM = 143.32 g/mol) has a Ksp of 1.7 x10-10.  If 95.7 g AgCl is stirred into 26.94 L H2O, how many milligrams of silver chloride will dissolve? Report your answer to the nearest whole number.

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.

Given the different volumes in Table 3.1, what are the concentrations of [S2O8], [I-] and [S2O3 2-]
