hydrochloric acid has been reported to cause gastritis, chronic bronchitis, dermatitis, and photosensitization in workers. Prolonged exposure to low concentrations may also cause dental discoloration and erosion. Hydrochloric Acid is a strong chemical compound. It is a powerful substance with many uses. The bonding in hydrochloric acid is the reason why it has a high The two elements making up hydrochloric acid are Hydrogen and Chlorine. Each molecule of hydrochloric acid is made up of one

conflicting an alteration that deviates from the norm. In other words, deviation produces negative responses to counteract the deviation. Metabolism is the amount of all the chemical reactions occurring in a specific order. When metabolism is broken down it is called biochemical reactions in which thousands of chemical reaction takes place, all in the same specific order. The cycle in which the reactions takes place is takes just under twenty four hours to complete, once completed; the cycle

Introduction Chlorite is a general name for a group of magnesium rich hydrous sheet silicates possessing similar structure and chemical composition. Many green rocks owe their color to chlorite and chlorite owes its name to its green color. The Greek word choros, meaning “green,” is the origin of chlorite’s name. Consisting of negatively charged mica-like (2:1) layers regularly alternating with positively charged brucite-like (octahedral) sheets, the basic structure of chlorites allows for various

Introduction Enzymes are biological catalysts. Catalysts are substances that increase the rate of chemical reactions without being used up themselves. Enzymes are also proteins. They all have different and complex shapes that allow smaller molecules to fit into them. The place where these substrate molecules fit is called the active site. The shape of an enzyme can change; its active site may no longer work. It is said the enzyme is denatured. They can be denatured by high temperatures or extremes

reactive. Compare properties of molecules formed from atoms in similar families; for example, H2S versus H2O. Explain what is meant by the electronic structure of atoms. How does knowing the electronic structure of atoms aid chemists in predicting chemical reactions? Periodic Table is designed to help us understand how elements are going to react to each other and also gives us the breakdown of how many atoms are in each element. This chart also helps us to identify metals, liquids, and gases. This
