50 POINTS!!! Please help! It's urgent! Please explain in detail. Some household cleaners come in concentrations stronger than necessary for basic cleaning jobs. Jeremy followed the instructions on a cleaning bottle and mixed enough cleaner with 4.0 L of water to form a 1.0 M cleaning solution. After testing his cleaning solution, he decided he should double to concentration for a tough stain. Jeremy added the same amount of cleaner and then added another 4.0 L of water to his bucket. Did Jeremy succeed in making a more concentrated solution? Explain why or why not.

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.
