The difference between the boiling point of a pure solvent and the boiling point of a solution of a nonelectrolyte in the same solvent is called the , a colligative property. A. boiling-point elevation
B. freezing-point depression
C. molar freezing-point constant
D. molal melting-point constant
E. molal boiling-point constant

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What does an electron configuration for an atom relate to the atoms placement on the periodic table

Which conclusion fits the data in the table? a. heat chemically changes chocolate and margarine. b. all solids become liquid at 100°f. c. removing heat from a substance it to melt. d. matter may change shape when it is heated.
