Which of the following describes the melting point of a solid? A. The temperature at which intermolecular forces become stronger
than kinetic energy
B. The temperature at which molecular motion is unaffected by
intermolecular forces
C. The temperature at which the effects of heating exceed the
effects of pressure
D. The temperature at which the kinetic energy overcomes the
intermolecular forces

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.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)

What are the trends and exceptions to the trends in electron affinity?
