Rank the following solutions from least polar to most polar. Rank on a scale of 1-4: 1 being the least polar and 4 being the most polar.

(a) 50% isopropanol/H2O,
(b) 25% isopropanol/H2O,
(c) pure water,
(d) 70% isopropanol/H2O.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
