Water gas (a mixture of carbon monoxide and hydrogen) is prepared by passing steam over red-hot coke: c(s) + h2o(g)
→co(g) + h2(g)for many years, water gas was used as a fuel in industry and for domestic cooking. compare the heat produced by the complete combustion of 1 mole of methane (ch4) with a mole of water gas (0.50 mole h2 and 0.50 mole co) under standard conditions. (assume liquid water is formed.) what is the difference between the two values? (in kj/mol)

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.
