Aselectively permeable membrane divides a container in half. one half of the container, side a, is filled with a starch solution, while the other half, side b, is filled with an iodine tincture. starch is a large macromolecule that forms a milky white solution when dissolved. an iodine tincture contains very small iodide ions and is a brown solution. iodide ions turn dark blue when they react with starch molecules. after several hours, side a is dark blue, while side b is brown. which statement describes the diffusion of solutes through the membranea. the membrane excluded the iodide ions, but the starch molecules diffused through. b. both the starch molecules and the iodide ions diffused through the membrane. c. the membrane excluded both the starch molecules and the iodide ions .d. the membrane excluded the starch molecules, but the iodide ions diffused through.

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
