Compare the diagrams of the chemical structures of the two major categories of energy providing molecules in our food: carbohydrates and lipids. What is it about the structure of lipids that causes them to contain so many more calories than an equivalent volume of carbohydrates

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.
