The reactants of two chemical equations are listed. Equation 1: CuSO4 and NaOH Equation 2: Fe and CuSO4 Based on the type of reaction, which reaction can be used to extract copper metal from copper sulfate solution? (5 points) Select one: a. Equation 2, because Fe being more reactive, replaces Cu from CuSO4 b. Equation 2, because Fe being more reactive, replaces S from CuSO4 c. Equation 1, because Na being more reactive, exchanges position with Cu in CuSO4 d. Equation 1, because Na being more reactive, exchanges position with S in CuSO4

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.
