acids and bases and producing water and a salt. Acids contain Hydrogen Ions and Bases contain Hydroxide Ions. The best example of neutralization in our bodies is the carbonic acid bicarbonate buffer. It contains acid and base and maintains our bloods Ph level. If our blood becomes acidic or basic this buffer neutralizes conditions. 4) C6H12O6+6O2-->6CO2+6H2O a) Carbon atoms in glucose are being oxidized b) Oxygen is being reduced Unit 1 Lesson 2 Key Questions 5)a) Carbohydrates monomer(s)

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

experiment will take place over a one month period. I will take two pennies (minted before 1983) and place each one in their own glass. (U.S. Environmental Protection Agency. n.d.) I will then place ½ cup of water with a pH level of 4.5 in one glass and a ½ cup of water with a pH level of 5.6 in the other glass. After the one month period‚ I will note the differences between the two pennies and determine if the penny in the acidic water is more corroded then the penny in “normal” water. That will

1. Identify the natural sources of sulphur dioxide and oxides of nitrogen. SO2‚ natural: - Geothermal hot springs and volcanic activity are natural sources of SO2. - In the process of decaying of organic matter some bacteria will produces hydrogen sulphide as a waste product which will oxidise‚ forming so2. - Phytoplankton release dimethyl sulphide (DMS) into the atmosphere‚ when this is oxidised it forms sulphuric acid. NOx‚ natural: - Lightning activity generates high temperatures to allow

The Power of Vital. Undoubtedly‚ the most important component to human health and vitality of oxygen. In fact‚ human life would not be possible without it: oxygen produces ATP (adenosine triphosphate) and within ATP our bodies would immediately shut down. When a person breathes‚ there is an exchange of carbon dioxide and oxygen. The oxygen‚ which is taken in by the body from the atmosphere around us‚ is picked up by the hemoglobin in the blood and distributed to all of the body’s trillions of

Module 7 Exam Review ANSWER KEY 1. Define acid. (7.01) An acid is a substance that produces hydrogen ions‚ H+ or hydrodium ionsH3O+ in solution. 2. Compare the three theories of acids. (7.01) An Arrhenius acid is a substance the increases the concentration of hydrogen ion‚ H+ or hydronium ions H3O+when dissolved in water. You must have water. A BrØnsted-Lowry acid is any substance that donates a hydrogen ion‚ H+ to another substance. A Lewis acid is any substance that accepts a lone pair
