IV Lecture Exam with these concepts. 1. Gossip‚ an undergraduate‚ has normal PCO2 levels‚ high H+ levels‚ low pH and bicarbonate levels. What type of disturbance is Gossip suffering from and what might cause this? If his PCO2 were elevated‚ would your answer change? Explain. 2. Diabetes mellitus produces many homeostatic imbalances‚ including acidosis. The pH imbalance is due to ketoacidosis‚ which results from excessive accumulation of byproducts of fat metabolism‚ as the body

DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. SELECTIVE PERMEABLE MEMBRANE=a membrane (as a cell membrane) that allows

Chemical decomposition can be defined as the separation of chemical compounds into smaller‚ simpler compounds (New World Encyclopedia‚ 2009). It is often considered an undesirable outcome of a chemical reaction. Radiation‚ humidity‚ heat‚ and acidity affect the stability of chemical compounds. Molecules‚ when put under harsh environmental conditions may break up into smaller particles. Decomposition can also be defined as the breakdown of one phase into two or more phases. Thermal‚ electrolytic‚

disappear more slowly near the endpoint? (2I) At the start of the titration‚ the NaOH solution in the flask will be pinkish and the pH is quite high. As HCl drops are added‚ the indicator colour will change momentarily to colourless as the pH is lower in the area around the drop(s). As the endpoint nears‚ the clear colour disappears more slowly as the solution has a lower pH than when the titration started. 3) What ions are taking part in the neutralization reaction? (2 I) The ions taking part

Experiment 6 Preparation and reactions of boric acid Objectives: To prepare boric acid from sodium tetraborate (borax) To carry out tests on the prepared sample of boric acid To study the physical and chemical properties of boric acid Introduction: Boron is an element in the p-block of the periodic table. It has the electron configuration of 1s22s22p1 and is in group 3 or goup 13 (IUPAC classification). In nature‚ it consists of two isotopes 10B (19.6%) and 11B (80.4%). Boron is bonded

The effects of initial Ag (I) concentration‚ contact time‚ solution pH and coexisting ions on the adsorption capacity of Ag (I) were systematically investigated. Moreover‚ the chelating resin could selectively adsorb more Ag (I) ions than other heavy metal ions including: Cu (II)‚ Zn (II)‚ Ni (II)‚ Pb (II) and Cr (III)

to a rapid decline in the numbers of the mangroves in any environment. A relatively simple example of this would be to project the effects of having a sudden decrease in the pH levels of the water and soil surrounding the mangroves. This could easily occur due to pollution and improper disposal of waste products. At lower pH levels (more acidic environments)‚ the mangroves will begin to be poisoned. Aside from the obvious corrosive properties of having an acidic environment‚ elements such as manganese
