When 82.5 g of calcium nitrate reacts with 25.0 g of aluminum nitride forms calcium
nitride and aluminum nitrate.
3 Ca(NO3)2 (aq) + 2 AIN (s) → Caz N2 (s) + 2
Al(NO3)3 (aq)
How much aluminum nitrate is produced?
(Include correct units and significant figures in your answer)

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.
