Micelles stay in the soap solution as colloid since: negative charges from polar heads repel each other positive charges from polar heads are attraced to each other positive charges from polar heads repel each other negative charges from polar heads are attracted to each other 3.The soap that would take longer to lather has: shorter chained fatty-acid salts saturated carbon atoms longer chained fatty-acid salts more potassium ions

Compare a 1 M solution of glucose and a 1 M solution of NaCl for osmotic pressure, and MARK WITH AN "X" the true statement(s): glucose contains 6.02 x 1023 particles, NaCl has twice the number of particles (Na+ and Cl-) and twice the osmotic pressure. Osmotic pressure depends on the total number of dissolved particles in the solution, so that ions count as separate particles. glucose contains 6.02 x 1023 particles, NaCl has twice the number of particles (Na+ and Cl-) and both have the same osmotic pressure. both solutions contain 6.02 x 1023 particles, both have the same osmotic pressure.
