Reactions involving a very large molecule such as a protein or DNA often depend on how well the molecules align with other large complex molecules. For example, some proteins can interact with DNA in a way that can help prevent cancer. Which type of molecular model would be most useful in studying this type of interaction between large complex molecules? Explain your answer.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
