Imagine you are about to investigate what happens when sodium and potassium are
mixed together. Before you begin your experiment, a peer tells you this reaction is
impossible, as both elements will not react to chemically bond to one another. Type a
paragraph statement explaining why this is true. Be sure to relate this cause to
chemical bonding and the elements positions on the periodic table.

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.
