Chemistry is one of the major branches of science. People who work in chemistry are called chemists. Chemists study the substances that make up matter everything that takes up space in the universe. They also study the changes that take place when substances are combined. These changes are called chemical reactions. Interactive chemistry - Students Britannica Kids Homework HelpA compound is made up of two or more elements that have undergone a chemical change. Water, sugar, baking soda, and salt are examples of familiar compounds. Encyclopædia Britannica, Inc. organic chemistry - Students Britannica Kids Homework The three simplest hydrocarbons (methane, ethane, propane) and the corresponding radicals or combining groups are shown, using each type of formula. These hydrocarbons differ from each other only in the number of HCH units in the chain. The series runs up to C 60 H 122.
