Imagine a small amount of each compound in the table below is dissolved in water. Pick the sketch that best shows what the solution would look like, at the atomic level. The large number of faint red and white molecules in the background of each sketch represent the water solvent. Also, the colors of the solute atoms may not mean the same element in each sketch. For example, solute oxygen atoms could be colored yellow in the first sketch but blue in the second. Chlorine atoms could be colored blue in the first sketch but yellow in the second. And so on. Note for advanced students: the sizes of the atoms and any bond angles may not be accurate. pick a sketch compound VCI, (Drag the slider to choose an image) X P

A sample of drinking water is determined to be contaminated with dioxin. The mass percentage of dioxin in the sample is 0.085%. If the water sample has a volume of 2.5 L, how many grams of dioxin are present in the sample? Assume the density of the solution is 1.00 g/mL.

Suppose 2.33g of zinc chloride is dissolved of zinc chloride is dissolved in 300. mL of a 51.0 mM aqueous solution of potassium carbonate. Calculate the final molarity of zinc cation in the solution. You can assume the volume of the solution doesn’t change when the zinc chloride is dissolved in it.

Magnesium hydroxide is not soluble in water. When magnesium hydroxide and water are combined what type of matter is formed?

You dissolve 6.64 mol of NaCI into a total volume of 6.91 L. What is the molarity of NaCI in the resulting solution. (Give your answer in units of M, with two places after the decimal point.)

You have a solution which is 47.8% by mass isopropyl alcohol (MM = 60.11 g/mol) in water. The density of this solution is 0.905 g/mL. What is the molarity of the isopropyl alcohol in the solution?

Suppose you had a sample of a white crystalline solid that was a mixture of calcium carbonate and calcium chloride. Describe how you could treat the sample to isolate one of the solid in the pure state. Which solid would it be.

In the laboratory you dilute 2.56 mL of a concentrated 12.0 M hydrochloric acid solution to a total volume of 100 mL. What is the concentration of the dilute solution? M

Consider a solution prepared by combining 45.0 g of BaCl2 with enough water to prepare a 750.0 mL of solution.  Assume that the volume of water added was 748 mL.  Density of water is 1.00 g/mL.  1)  What volume of this solution would be required to prepare 500.0 mL of a solution that is 0.0034 M in BaCl2?
