Draw all products of the reactions of 4-Chloro-2-methylpentane with NaCN and AgCN. Identify the reaction mechanisms and draw resonance structures of the cyanide anion.
determine the specific heat capacity of a metal that has a mas of 14 grams. As the metal cools from 400 degrees celcius to 200 degrees celcius, 364 joules of heat is released
Suppose you wanted to find out how many milliliters of 1.0 M AgNO3 are needed to provide 169.9 g of pure AgNO3.
When 1.00 g of urea (CO(NH2)2) is dissolved in 200g of solvent A, the freezing point is lowered by 0.250C. When 1.50 g of the nonelectrolyte Y is dissolved in 125 g of the same solvent
When 7 mL of a solution containing 3 M KNO3 is diluted to 21mL, a dilute solution is formed. What is the NO3- concentration in 10mL of the dilute solution?
A gas bottle contains .65 mol of gas at 730 Hg pressure. If the final pressure is 1.15 atm, how many moles of gas were added to the bottle?
