Predict how many compounds you can make from the elements below. Pick one element from the metal list and two from the nonmetal list. For example, "If I use sodium, hydrogen, and oxygen, then I can make ten new compounds in five minutes."

Now, you try! Make a prediction. Be sure to record your prediction on your lab report.

Metal Nonmetal

• Sodium (Na)

• Calcium (Ca)

• Hydrogen (H)

• Oxygen (O)

• Carbon (C)

• Chlorine (Cl)

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.

The pressure inside a hydrogen-filled container was 2.10 atm at 21 ? c. what would the pressure be if the container was heated to 92 ? c ?
