To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

  • Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
  • Ionic charges are not yet supported and will be ignored.
  • Replace immutable groups in compounds vĩ đại avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
  • Compound states [like (s) (aq) or (g)] are not required.
  • You can use parenthesis () or brackets [].

Balance Fe + Fe2(SO4)3 = FeSO4 Using the Algebraic Method

How To Balance Fe + Fe2(SO4)3 = FeSO4

To balance the equation Fe + Fe2(SO4)3 = FeSO4 using the algebraic method step-by-step, you must have experience solving systems of linear equations. The most common methods are substitution/elimination and linear algebra, but any similar method will work.

  1. Label Each Compound With a Variable

    Label each compound (reactant or product) in the equation with a variable vĩ đại represent the unknown coefficients.

    a Fe + b Fe2(SO4)3 = c FeSO4

  2. Create a System of Equations

    Create an equation for each element (Fe, S, O) where each term represents the number of atoms of the element in each reactant or product.

    Fe: 1a + 2b = 1c S: 0a + 3b = 1c O: 0a + 12b = 4c

  3. Solve For All Variables

    Use substitution, Gaussian elimination, or a calculator vĩ đại solve for each variable.

    • 1a + 2b - 1c = 0
    • 3b - 1c = 0
    • 12b - 4c = 0

    Use your graphing calculator's rref() function (or an online rref calculator) vĩ đại convert the following matrix into reduced row-echelon-form:

    [ 1 2 -1 0] [ 0 3 -1 0] [ 0 12 -4 0]

    The resulting matrix can be used vĩ đại determine the coefficients. In the case of a single solution, the last column of the matrix will contain the coefficients.

    Simplify the result vĩ đại get the lowest, whole integer values.

    • a = 1 (Fe)
    • b = 1 (Fe2(SO4)3)
    • c = 3 (FeSO4)
  4. Substitute Coefficients and Verify Result

    Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced.

    Fe + Fe2(SO4)3 = 3 FeSO4

    Reactants Products

    Since there is an equal number of each element in the reactants and products of Fe + Fe2(SO4)3 = 3FeSO4, the equation is balanced.

Balance Fe + Fe2(SO4)3 = FeSO4 Using Inspection

The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the over of a chemical reaction as at the beginning. To be balanced, every element in Fe + Fe2(SO4)3 = FeSO4 must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used vĩ đại balance one element at a time until both sides are equal and the chemical equation is balanced.

1. Count the number of each element on the left and right hand sides

Reactants (Left Hand Side)Products (Right Hand Side)

2. Multiply coefficients for compounds vĩ đại balance out each element

For each element that is not equal, try vĩ đại balance it by adding more of it vĩ đại the side with less. Sometimes there may be multiple compounds with that element on one side, so sánh you'll need vĩ đại use your best judgement and be prepared vĩ đại go back and try the other options.

  1. Fe is not balanced. Add 2 molecules of FeSO4 vĩ đại the product (right-hand) side vĩ đại balance Iron:
    Fe + Fe2(SO4)3 = 3FeSO4


3. Verify that the equation is balanced

Since there are an equal number of atoms of each element on both sides, the equation is balanced.

Fe + Fe2(SO4)3 = 3FeSO4
