QUESTION 26 A student finds that 15.2 g of nitrogen will react with (A) 17.37 g (B) 34.74 g or (C) 43.43 g of oxygen to form three
different compounds.
1. Determine the mass of oxygen per gram of nitrogen for each of these three
compounds.
2. Divide your answers in 1) by the smallest value to try and obtain a whole number ratio
for the three masses (of oxygen). With what integer can you multiply these three
numbers to obtain whole numbers for them all?
3. Which Law is illustrated

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.
