Hi! I need your answers on numbers 2-3. This talks about simple distillation. One of the factors that affect the boiling point of compounds is molecular weight – higher molecular weightmeans higher boiling point due to increasing intramolecular forces of attraction. Which will be isolated first if amixture of the following will be separated by distillation?O a. Diethyl ether (C4H100)O b. Dipropyl ether (C6H140)O c. Butyl propyl ether (C7H160)O d. Ethyl propyl ether (C5H120)If the first 1 mL distillate is not removed, there will be a/anin the purity andin the per centyield.O a. Decrease; decreaseO b. Decrease; increaseO c. No effect; increaseO d. Decrease; no effectWhich of the following is FALSE regarding a distillation set-up?Select one:O a. Boiling chips are placed in the distilling flask.O b. The water around the condenser is kept cool to increase recovery.O c. The first twenty drops of the distillate are discarded.O d. The water outlet is located closer to the receiving flask.

2). In the distillation process initial, some drops or some amount of distillate is removed because…

If a water sample has 0.07 mol of calcium ions in 15 L solution, what is the water hardness level in mg/L? Pay attention to the unit. Hint: For the calcium mass , convert mol to g to mg. (1 mol calcium ion= 40.08 g/mol and 1 g = 1000 mg) Round and report your answer to an integer without decimal place. Report numeric value only, no unit. • Water hardness levels according to EPA Soft: 0-60 milligrams per liter (mg/L) as calcium carbonate Moderately hard: 61-120 mg/L as calcium carbonate • Hard: 121-180 mg/L as calcium carbonate Very hard: more than 180 mg/L as calcium carbonate
Your 50 mL beaker has a mass of 6.65 g. You add 10.00 mL to the 50 mL beaker and now the total mass is 17.45 g. You originally used 5.14 g of NaCl to make the solution. What is the percent composition of your solution? These calculations are described in the lab procedure in detail.

Answer 2a and b please
67. Pure bromobenzene, C H Br, boils at 156.0°C and has a boiling point constant of 6.26°C/m. A sample of bromo benzene is contaminated by anthracene, C4H10. The boiling point of the impure sample is 159.2°C. How pure is the sample? (Express your answer as mass percent bromobenzene.) I've spent forever trying to figure this out. For now my answer is 6.56%, but it doesn't seem right. Before, I got 97.9%. are either of those correct?
