Step 1: Label Each Compound With a Variable

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

a KClO3 + b KCl = c KClO

Step 2: Create a System of Equations

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

K: 1a + 1b = 1c Cl: 1a + 1b = 1c O: 3a + 0b = 1c

Step 3: Solve For All Variables

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

  • 1a + 1b - 1c = 0
  • 1a + 1b - 1c = 0
  • 3a - 1c = 0

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

[ 1 1 -1 0] [ 1 1 -1 0] [ 3 0 -1 0]

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

Simplify the result đồ sộ get the lowest, whole integer values.

  • a = 1 (KClO3)
  • b = 2 (KCl)
  • c = 3 (KClO)

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.

KClO3 + 2 KCl = 3 KClO

Reactants Products

Cl33✔️
O33✔️

Since there is an equal number of each element in the reactants and products of KClO3 + 2KCl = 3KClO, the equation is balanced.
