Question: Acetylene, C, H, is a colorless gas which burns with a brilliant flame. Acetylene torches are used by welders for cutting and soldering metals. Acetylene is produced by the reaction of calcium carbide, CaC2,(s), in water according to the following equation: CaC2,(s) + 2H2O(l) —-> C2H2(g) + Ca(OH)2(aq)

How many moles of CaC2 (s) must react with water to produce 2.25 moles C2H2(g)?
[Explain 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.
