An Introduction to chemical change

A chemical change is a process that alters the chemical composition of a substance. This can be done by either breaking down the substance into smaller pieces or by combining it with other substances to create a new compound.

    Examples of Chemical Change - Explanation, Properties, and FAQs

    What is a Chemical Change?

    A chemical change is a process in which one or more substances are changed into new substances. The atoms in the new substances are different from the atoms in the original substances.

    The Properties of Chemical Changes

    A chemical change is a process that alters the chemical composition of a substance. Therefore the properties of a chemical change can include the formation of a new substance, the destruction of a substance, the release of energy, or a change in the physical state of a substance.

    The significant properties of chemical changes given below.

    Chemical changes involve a change in the chemical composition of a substance. Therefore the atoms in the substance rearranged, and new substances formed. This can involve the breaking and forming of chemical bonds.

    The energy required for a chemical change is called the activation energy. However the activation energy the energy needed to break the initial bonds and start the reaction.

    The rate of a chemical reaction determined by the activation energy and the concentration of the reactants. The higher the concentration of the reactants, the faster the reaction will occur.

    Examples of a Chemical Change

    A chemical change is a process that alters the chemical composition of a substance. Some common examples of chemical changes include the burning of fuel, the rusting of metal, and also the ripening of fruit.

    Examples of Chemical Change

    1. The reaction of iron with oxygen to form iron oxide.
    2. The reaction of calcium with water to form calcium hydroxide.
    3. The reaction of baking soda with vinegar to produce carbon dioxide gas.
    4. The reaction of sugar with an enzyme to produce glucose and fructose.
    5. Therefore the reaction of an acid with a metal to produce salt and hydrogen gas.
