14. For each compound, draw the Lewis structure, determine the geometry using VSEPR theory, determine whether the molecule is polar a. COF2 (carbon is the central atom) b. S2Cl2 (ClSSCl) c. SF4

Does the energy in a solid increase or decrease when changing to a liquid?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
