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 lớn 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 CH3OH + CO = CH3COOH Using the Algebraic Method
To balance the equation CH3OH + CO = CH3COOH 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.
Label Each Compound With a Variable
Label each compound (reactant or product) in the equation with a variable lớn represent the unknown coefficients.
a CH3OH + b CO = c CH3COOH
Create a System of Equations
Create an equation for each element (C, H, O) where each term represents the number of atoms of the element in each reactant or product.
C: 1a + 1b = 2c H: 4a + 0b = 4c O: 1a + 1b = 2c
Solve For All Variables
Use substitution, Gaussian elimination, or a calculator lớn solve for each variable.
- 1a + 1b - 2c = 0
- 4a - 4c = 0
- 1a + 1b - 2c = 0
Use your graphing calculator's rref() function (or an online rref calculator) lớn convert the following matrix into reduced row-echelon-form:
[ 1 1 -2 0] [ 4 0 -4 0] [ 1 1 -2 0]
The resulting matrix can be used lớn determine the coefficients. In the case of a single solution, the last column of the matrix will contain the coefficients.
Simplify the result lớn get the lowest, whole integer values.
- a = 1 (CH3OH)
- b = 1 (CO)
- c = 1 (CH3COOH)
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.
CH3OH + CO = CH3COOH
Reactants Products C 2 2 ✔️ H 4 4 ✔️ O 2 2 ✔️
Since there is an equal number of each element in the reactants and products of CH3OH + CO = CH3COOH, the equation is balanced.
Balance CH3OH + CO = CH3COOH 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 CH3OH + CO = CH3COOH 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 lớn 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)|
The number of atoms of each element on both sides of CH3OH + CO = CH3COOH is equal which means that the equation is already balanced and no additional work is needed.
