A theoretically computed equilibrium constant for the polymerization of formaldehyde, HCHO to glucose, C6H12O6 in aqueous solution is 6.0 x 1022.
6HCHO → C6H12O6
If a 1.00 M solution of glucose were to reach a dissociation equilibrium with respect to the above equation, what would be the concentration of formaldehyde in the solution?
Select one:
1.7 x 10-23 M
1.6 x 10-4 M
6.3 x103 M
1.0 x 10-22 M
The molar mass of cellulose is approximately 6.0 x 105 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 103 g/mol. The monomer unit in both of these molecules has the empirical formula C6H10O5. The units are about 5.0 x 10-10 m long. About how many units occur in each molecule, and how long are the molecules of cellulose and starch as a result?
Both proteins and nucleic acids (like DNA and RNA) can be denatured with heat.
Explain why this happens for both types of molecule and what is happening during
the heat-driven denaturing process. A complete answer should discuss
thermodynamic considerations such as entropy and enthalpy.

Zn(s) 2HCI(aq)ZnCl2(aq) + H2(g) Zinc + Hydrochloric Acid Zinc Chloride + Hydrogen What causes the reaction to proceed faster with concentrated acid? The concentrated hydrochloric acid causes more hydrogen gas to be produced. The pressure of hydrogen gas molecules increases as concentration increases. The concentrated hydrochloric acid molecules move faster than in dilute acid. There are more collisions between the zinc and concentrated hydrochloric acid.
