You are attempting to recrystallize a crude product mixture. you add the appropriate amount of hot solvent and are allowing the solution to slowly cool to room temperature. however, at room temperature no crystals have appeared, which of the following methods should be used to induce crystallization? choose all correct answers. a) place the flask in an ice bath. b) swirl the contents of the flask. c) add a small seed crystal of the desired product. d) scratch the inside of the glassware using a stir rod. it can be multiple choices

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
