Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.

Description: biological systems 5 differ from chemical systems when it comes to equilibrium. in a chemical system once equilibrium is met, no other reactions occur. in a biological system, a dynamic equilibrium is used when a substrate is turned into a product, another reaction creates the same substrate thus keeping the concentrations stagnant. this allows for cells to continually make new compounds without messing the delta g for the systems instructions: write a response to the following prompt and then respond to your peers. your individual response is due thursday at midnight (cst) your response to your peers is due saturday at midnight (cst) prompt: propose what would happen if a living cell all the sudden reached chemical equilibrium. also discuss the effects of build up of a particular substrate on a biological system. how would this affect overall delta g's?
