Name the following Fe(NO3)2

Q Sodium chloride (NaCl) was isolated from SiO2 and CaCO3 by dissolving it in distilled water. Calcium carbonate (CaCO3) is in fact slightly soluble in water (0.001 g/100 mL). What effect will this have on NaCl from the mixture: will the "isolated" mass be greater than, equal to, or less than that in the sample? Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. a b с Question 6 Greater than Equal to Less than

You collect a sample of seawater containing salt. The original sample weighs 15.67 g. You dry the sample until there is no remaining water. You weigh it again. 0.78 g of salt remains. What was the percent of salt in the sample? Round to the nearest percent.

How will you prepare 70 mL of 0.8% (w/v) CsCl?  A. Put 0.56 g CsCl into a beaker then add 64.4 mL distilled water. B. Put 0.056 g CsCl into a beaker then add distilled water until it reaches the 70 mL mark. C. Add 5.6 g CsCl to 70 mL distilled water into a beaker. D. Add 0.56 g CsCl into a beaker then add 70 mL distilled water.

12. A 15.00g sample of a solid substance is placed in 100.0 g of water at 25°C, and all of the solid dissolves. Then another 2.00 g of the substance is added, and all of it dissolves. A final 2.00 g is added, and none of it dissolves. a. Is the first solution saturated, unsaturated, or supersaturated? b. Is the second solution saturated, unsaturated, or supersaturated? C. What can you tell about the final solution that is in contact with the solid?

Is distillation a good method for separating a mixture of water and hexane?  Why or why not?

3. As we have seen, hexane is nonpolar and if mixed with water would not dissolve. Instead two layers would form. The density of hexane is 0.66 g/mL whereas the density of water is 1.00 g/mL. Which compound would form the top layer, hexane or water? Briefly explain why this would be the case. 54

4. How sizing down to Nano affect material properties?

Use the information below to answer questions 1- 3. PCI,(g) 2 PCI;(g) + Cl2(8) PCI,(g) decomposes into PCI,(g) and Cl,(8) according to the equation above. A pure sample of PCI,(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCI5(g) is 1.00 atm. The temperature is held constant until the PCI,(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. PCI5 Potal = 1.00 atm PCI5, PCI3, and CI, Prstal = 1.40 atm Figure 1: Initial Figure 2: Equilibrium As the reaction progresses toward equilibrium, the rate of the forward reaction (A) increases until it becomes the same as the reverse reaction rate at equilibrium (B) stays constant before and after equilibrium is reached (C) decreases to become a constant nonzero rate at equilibrium (D) decreases to become zero at equilibrium If the decomposition reaction were to go to completion, the total pressure in the container would be (A) 1.4…
