Instructions

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 to 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 ZnSO4 + CuO = CuSO4 + ZnO Using the Algebraic Method

To balance the equation ZnSO4 + CuO = CuSO4 + ZnO 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.

Step 1: Label Each Compound With a Variable

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

a ZnSO4 + b CuO = c CuSO4 + d ZnO

Step 2: Create a System of Equations

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

Zn: 1a + 0b = 0c + 1d S: 1a + 0b = 1c + 0d O: 4a + 1b = 4c + 1d Cu: 0a + 1b = 1c + 0d

Step 3: Solve For All Variables

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

Using Substitution or Elimination

• 1a - 1d = 0
• 1a - 1c = 0
• 4a + 1b - 4c - 1d = 0
• 1b - 1c = 0

Using Linear Systems / Algebra

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

[ 1 0 0 -1 0] [ 1 0 -1 0 0] [ 4 1 -4 -1 0] [ 0 1 -1 0 0] The resulting matrix can be used to determine the coefficients. In the case of a single solution, the last column of the matrix will contain the coefficients. Convert to RREF and Solve Step-by-Step

Simplify the result to get the lowest, whole integer values.

• a = 1 (ZnSO4)
• b = 1 (CuO)
• c = 1 (CuSO4)
• d = 1 (ZnO)

Step 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.

ZnSO4 + CuO = CuSO4 + ZnO

Reactants	Products
Zn	1	1	✔️
S	1	1	✔️
O	5	5	✔️
Cu	1	1	✔️

Since there is an equal number of each element in the reactants and products of ZnSO4 + CuO = CuSO4 + ZnO, the equation is balanced.

Balance ZnSO4 + CuO = CuSO4 + ZnO 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 end of a chemical reaction as at the beginning. To be balanced, every element in ZnSO4 + CuO = CuSO4 + ZnO 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 to balance one element at a time until both sides are equal and the chemical equation is balanced.

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

Reactants (Left Hand Side)			Products (Right Hand Side)
Reactants	Products
ZnSO4	CuO	Total	CuSO4	ZnO	Total
Zn	1	1	1	1	✔️
S	1	1	1	1	✔️
O	4	1	5	4	1	5	✔️
Cu	1	1	1	1	✔️

The number of atoms of each element on both sides of ZnSO4 + CuO = CuSO4 + ZnO is equal which means that the equation is already balanced and no additional work is needed.

Practice Balancing

ZnSO4 - + + CuO - + = CuSO4 - + + ZnO - +

Reactants	Products
Zn	1	1	✔️
S	1	1	✔️
O	5	5	✔️
Cu	1	1	✔️

Hint: The sum of the balanced coefficients is 4. See Step-By-Step Solution
