Sulfur is known for having many properties. These properties are both physical and chemical properties. To start with, the first physical property that Sulfur is known for having would be that its insoluble in
Sulfuric acid is a liquid that is colorless and corrosive. Sulfuric acid is used with varying degrees of concentrations in manufacturing processes and in petroleum refining. When sulfuric acid is heated it decomposes into water and sulfur trioxide. Sulfuric acid is very strong and a great oxidizing agent. It reacts readily with carbon, sulfur, and metals when it is at high temperatures (The Editors of Encyclopedia Britannica, 2014).…

BIOLOGY STUDY GUIDE CHAPTER 4– THE CHEMICAL BASIS OF LIFE Matter = anything that takes up space and has mass (major types of matter = solid, liquid, and gas) Any type of matter is made of one or more elements. o Element = a substance that cannot be broken down into other substances by regular chemical processes. (examples: gold, silver, mercury, etc.) There are approximately 25 elements necessary for life. • Examples: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorous, etc. • Trace elements = those elements that make up less than 0.01 percent of your body mass (examples: iodine, iron, copper, etc.) Compounds = a substance containing two or more elements; these elements are always present in this compound in the same ratio o For instance, water is a compound where hydrogen and oxygen are combined. The ratio of hydrogen to oxygen in water is always 2:1. (Remember that the chemical formula of water is H2O.) o Compounds have different characteristics than the elements that make them up. (Water is liquid at room temperature, but when hydrogen and oxygen are by themselves, they are gases at room temperature.) Atoms = smallest possible piece of an element o A better definition of an atom may be: the most basic unit of matter that cannot be broken down into smaller pieces by ordinary chemical methods. o This can be confusing, because when you read the above definition or when you start looking at the periodic table in class, is oxygen an atom or an element? o An element is essentially the same as an atom. Why do we bother with two different words? • An element is the most common version of an atom. The element you see on the periodic table for oxygen is the most common version of the oxygen atom that exists in nature. There are several different kinds of oxygen atoms (with different numbers of neutrons than the one found on the table), but they are not as commonly found in nature. All atoms are made of even smaller…

4. Physical Properties are those that describe ab substance or object without referring to any other substance. For example physical properties of glass, its weight, size, color, and volume. Chemical properties are those that describe what happens when a substance reacts with another substance. For example, when the drug heroin comes to contact with Marquis Reagent chemical it turns purple.…
