The mn department of natural resources has determined that a nearby lake contains 0.55g of chlorine in 1 L (1000 g) of water. what is the concentration of chlorine in ppm in the lake?
formula: ppm= mass solute / mass solution x 1,000,000

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)
