If a solute dissolves in an endothermic process select one: a. hydrogen bonds must exist between solvent and solute. b. strong ion-dipole forces must exist in the solution. c. the solute must be a gas. d. the entropy of the solution is immaterial. e. the entropy of the solution must be greater than that of its pure components.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
