The apparatus below is a glass tube with two cotton balls stuck in the ends. One cotton ball is soaked with an aqueous solution of HX while the other cotton ball is soaked with a volatile base. When HX and the base meet a white solid is produced and creates a vertical ring in the tube. In the following situations, determine if the white ring will form closer to HX, closer to the base, or near the middle. In each case, explain your reasoning. HX: HCl Base: CH3NH2
HX: HBr Base: CH3NH2
HX: HCl Base: CH3(CH2)6N H2

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
