Chemical Equation s and Chemical Reactions The chemical equation for producing water from hydrogen and oxygen is: 2H 2 + O 2 2H 2 O Notice that the reactants are written on the left and products on the right. In the equation above, hydrogen (H 2 ) and oxygen (O 2 ) are reactants; water (H 2 O) is the product. The equation below (bottom of diagram) is not balanced because the number of atoms on the left side of the arrow is not equal to the number on the right side. Matter cannot be created or destroyed as a result of a chemical reaction. In a balanced chemical equation, the number of atoms of each element on the left side of the equation is the same as the number on the right. Most chemical reactions are reversible. The arrow below indicates that the reaction is reversible. CO 2 + H 2 O H 2 CO 3 In the reaction above, carbonic acid (H

Unformatted text preview: 2 CO 3 ) accumulates when the concentration of CO 2 is high. A higher concentration of CO 2 produces a faster reaction due to more frequent molecular collisions. At low CO 2 concentration, the reaction moves toward the left, causing carbonic acid to break down and form CO 2 + H 2 O. An equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Important Concepts Regarding Covalent Bonds Energy and Covalent Bonds Energy is often defined as the ability to cause change. For example, movement requires energy. Energy is required to form a covalent bond and energy is released when a Covalent bond is broken. Covalent bonds can therefore be used by organisms to store energy. The energy that is stored can be used to perform work....
