Step 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 C₆H₅OH + b Na = c C₆H₅ONa + d H₂

Step 2: Create a System of Equations

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

C: 6a + 0b = 6c + 0d H: 6a + 0b = 5c + 2d O: 1a + 0b = 1c + 0d Na: 0a + 1b = 1c + 0d

Step 3: Solve For All Variables

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

6a - 6c = 0
6a - 5c - 2d = 0
1a - 1c = 0
1b - 1c = 0

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

[ 6 0 -6 0 0] [ 6 0 -5 -2 0] [ 1 0 -1 0 0] [ 0 1 -1 0 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 = 2 (C6H5OH)
b = 2 (Na)
c = 2 (C6H5ONa)
d = 1 (H2)

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.

2 C₆H₅OH + 2 Na = 2 C₆H₅ONa + H₂
