A pellet of Zn of mass 14.5g is dropped into flask containing dilute H2SO4 at a pressure P = 1.00bar, and temperature T= 325K. What is the reaction that occurs?
2-Methyl-1-propanol is more soluble in water than is glycerol because 2-methyl-1-propanol forms fewer hydrogen bonds with water. Glycerol is more soluble in water than is 2-methyl-1-propanol because glycerol can form multiple hydrogen bonds with wate..
