Suppose the provided unknown Q was a solution of 6.732 M Fe2+ and a concentration cell was constructed with one half-cell containing the provided unknown Q solution and an iron electrode, and the other half-cell containing a diluted unknown Q solution (diluted using the procedure listed in Part A) and an iron electrode, as shown below.

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

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.
