Students have asked these similar questions
The PH formula is given as PH=-log(H+). The H+ is the number of free ions of hydrogen. A seven PH is considered neutral. Discuss what having a low PH and a high PH means. What does a 12 PH mean? How about a 2? Which is more caustic? Is either a good thing at extremely high or low values? Explain fully as to what a PH means to you and what you use it for.
What is the difference between biochemical, pharmaceutical, and diagnostic chemical reactions?
What is a specific example that exists for each and why might they be important to healthcare professionals?
List a balanced chemical equation for each and explain how it is used in your example above.
A group of students designed an experiment to determine the impact of sucrose concentration on the weight of potato cubes. The pieces of potato were initially the same weight, shape, and size. Each potato piece was submerged into a beaker containing one of the sucrose concentrations for 30 minutes. The final weight of the potato was measured and recorded in the table.
Which TWO conclusions can be correctly drawn from this data?
A
In the 0.4 mol/dm3 solution, the sucrose molecules moved across the semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration (the sucrose solution), leading to a decrease in the weight of the potato.
B
In the 1 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato.
C
In the 0.8 mol/dm3 solution, the sucrose molecules moved…

- Looking at the two different types of molecules (glycerol and fatty acids), describe the molecules with respect to: a. Polarity b. Acidityarrow_forwardDespite the thermal stability of covalent bonds in physiological systems, some of these bonds are sensitive to energy input from external sources. The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. If the increase in energy is above kT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following physiological process is example to this? Select one : a. Absorbance of light by 11-cis-retinal. b. Translucent to opaque conversion of egg whites after cooking. C.
