Im a student, plz help w this question.

30. What weight of impure ferrous ammonium sulfate sample in milligrams must be taken for analysis so that the number of centigrams of BaSO4 will represent five times the % S in the sample? a. 230 mg b. 345 mg c. 460 mg d. 690 mg 31. If 100 mL of a dichromate solution (10 grams K2Cr2O7 per liter), 5 mL of 6 N H₂SO₁ and 75 mL of a ferrous solution (80 grams of FeSO4-7 H₂O per liter) are mixed, and resulting solution titrated with 0.2121 N KMnO4, what volume of is required KMnO4? a. 5.60 mL b. 5.80 mL c. 6.00 mL d. 6.20 mL

what is a soluble reactivity shim?

Pb(NO3)2 is placed in water. Please predict the physical state using our solubility rules from class. Select one: a. aqueous - (aq) b. liquid - (l) c. gas - (g) d. solid - (s) e. plasma - (p)

mixing instead of vigorously shaking them will help prevent emulsions from forming in the first place. 1. Questions 1. You are given a substance that is equally soluble in water and hexane (two immiscible solvents). a) What is K? b) If you start with 10 g of the substance dissolved in 100 mL of water and are given 100 mL of hexane to extract with, algebraically show that it is better to do two smaller extractions using 50 mL of hexane for each extraction than it is to do one extraction using 100 mL o hexane. 2. You have a solution that contains 4.0 g of oxalic acid dissolved in 100 mL of water. This solution is placed in a separatory funnel, and then 100 mL of diethyl ether is added to the separatory funnel and an extraction is performed. (Diethyl ether and water are immiscible solvents.) Use the following constants to calculate how much oxalic acid is in each solvent after the extraction. Solubility of oxalic acid in water = 9.5 g / 100 mL Solubility of oxalic acid in ether = 16.9 g /…

My professor said the answer choice was A.) please explain why in detail. Which of the following solutes, dissolved in 1.0Kg of water, creates a solution that boils at the highest temperature? A.) 0.010 mol H2SO4 B.) 0.010 mol HF C.) 0.010 mol HCL D.) 0.010 mol HCLO4 E.) 0.010 mol H3PO4

Rank the solubility of the compounds in benzene from most soluble to least soluble.

In the Flint Water Crisis, trihalomethanes were produced in the new water supply due to the mixing of   ? with ?   water.

What happens if a solute is added to a saturated solution?   A) Nothing will happen, solute will not mix with a saturated solution. B) The added solute provides a template for the solid to begin to crystallize from solution, and a precipitate will form. C) The added solute makes the solution less saturated. D) The added solute provides a template for the gas to begin to boil from solution, and a gas will form.   Why is A false?
