Methane is a colorless gas, and diamond is a hard solid. A methane molecule is made of one carbon atom surrounded by four hydrogen atoms. Diamond is an extended structure made of carbon atoms connected in a repeating pattern. Draw a model of a few methane molecules and a model of the extended structure in diamond. Use your model to explain whether methane and carbon are pure substances, such as compounds or elements, or are mixtures.

Read the assignment carefully and make sure you answer each part of the question or questions.
When you're done, look over your response closely to make sure your ideas are shown clearly.

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.
