When reacted, how does the use of potassium (K*) vs sodium (Na*) change the soap product? O Na* adds jasmine fragrance and K* adds a + rosemary fragrance to the soap. O K* produces harder, moldable soaps into shapes and Na* produces softer, liquid soaps. There is no difference between the two cations. Na* produces harder, moldable soaps into shapes and K* produces softer, liquid soaps.

How is hard water made soft ? Please explain the process .

if 5 mL 10 % v/v 1,6-Diaminohexane in 3% Sodium Hydroxide and 10 mL 2% v/v Sebacoyl Chloride in Hexanes is used to make nylon6,10. If each dimer is 20 angstroms in length, calculate approximately how long (in feet or miles) a strand of nylon can be formed
