    Study Notes

    Chemical Equations

    • The purpose of balancing a chemical equation is to ensure that the same number of atoms of each element is present on both the reactant and product sides.
    • A chemical equation that has the same number of atoms of each element on both the reactant and product sides is called a balanced equation.
    • The arrow (→) in a chemical equation indicates the direction of the reaction, separating the reactants from the products.
    • A formula equation uses chemical formulas instead of words to represent the reactants and products.
    • The term for the process of writing a chemical equation using chemical formulas and balancing it is equation writing or equation balancing.

    Chemical Equations

    • The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is the same on both the reactant and product sides.

    Balanced Chemical Equation

    • A chemical equation that has the same number of atoms of each element on both the reactant and product sides is called a balanced chemical equation.

    Arrow in Chemical Equations

    • The arrow (→) in a chemical equation indicates the direction of the reaction, from reactants to products.

    Formula Equations

    • A formula equation is a chemical equation that uses chemical formulas instead of words.

    Writing Chemical Equations

    • The term for the process of writing a chemical equation using chemical formulas and balancing it is called equation writing or equation balancing.

    Purpose of Chemical Equations

    • The purpose of writing a chemical equation is to represent a chemical reaction in a concise and symbolic way.

    Balanced Chemical Equation Result

    • A balanced chemical equation ensures that the Law of Conservation of Mass is upheld, meaning that matter is neither created nor destroyed in a chemical reaction.

    Characteristics of Balanced Chemical Equations

    • A characteristic of a balanced chemical equation is that the number of atoms of each element is the same on both the reactant and product sides.
    • The correct direction of the arrow in a chemical equation is from reactants to products, indicated by →.
    • One characteristic of a balanced chemical equation is that it does not have a fractional coefficient.
    • The purpose of coefficients in a balanced chemical equation is to balance the number of atoms of each element on both sides of the equation.
