Cl2(g) + 2nabr(aq) 2nacl(aq) + br2(l) the reaction given above is a single replacement reaction because: a. one of the reactants is a gas b. none of the reactants are solids c. chlorine replaces bromine d. the reaction proceeds spontaneously

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.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
