To do any extraction, you’ll need two liquids or solutions. They must be insoluble in each other. a. What does it mean to have 2 insoluble liquids or solutions? b. I have listed twelve liquids and solutions below. Identify if each solution is considered aqueous or organic. Water, acetone, 1.0 M NaOH, 1.0 M HCl, diethylether, brine (saturated sodium chloride in water), dichloromethane, 10% sodium bicarbonate solution, ethyl acetate, chloroform, ethanol, hexane. 2. Which of the organic liquid(s) from 1b...

5. i) Describe an algorithm that, upon input of a number n given in base 10, outputs the digits of n in base 8, starting from the rightmost. Esrample: If you are given the number 156, the output will be 432, because (156) 10 = (234)s. ii) What will be the complexity of the algorithm? You may assume that performing the division algorithm upon two numbers to find the quotient and remainder is the basic operation. (As a...
