For each event stated, indicate how the concentration of each species in the chemical equation will change to re-establish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration.

CoCl2−4(aq) + 6H2O(l) ↽⇀ 4Cl−(aq) + Co(H2O)2+6(aq)
a. increasing the concentration of Cl−
b. decreasing the amount of H2O
c. increasing the concentration of CoCl2−

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)
