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 C6H5CHOHCN = C6H5CHO + HCN Using the Algebraic Method
To balance the equation C6H5CHOHCN = C6H5CHO + HCN 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 C6H5CHOHCN = b C6H5CHO + c HCN
Step 2: Create a System of Equations
Create an equation for each element (C, H, O, N) where each term represents the number of atoms of the element in each reactant or product.
C: 8a = 7b + 1c H: 7a = 6b + 1c O: 1a = 1b + 0c N: 1a = 0b + 1cStep 3: Solve For All Variables
Use substitution, Gaussian elimination, or a calculator to solve for each variable.
Using Substitution or Elimination- 8a - 7b - 1c = 0
- 7a - 6b - 1c = 0
- 1a - 1b = 0
- 1a - 1c = 0
Use your graphing calculator's rref() function (or an online rref calculator) to convert the following matrix into reduced row-echelon-form:
[ 8 -7 -1 0] [ 7 -6 -1 0] [ 1 -1 0 0] [ 1 0 -1 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-StepSimplify the result to get the lowest, whole integer values.
- a = 1 (C6H5CHOHCN)
- b = 1 (C6H5CHO)
- c = 1 (HCN)
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.

Balance C6H5CHOHCN = C6H5CHO + HCN 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 C6H5CHOHCN = C6H5CHO + HCN 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 | |||||
C6H5CHOHCN | Total | C6H5CHO | HCN | Total | ||
C | 8 | 8 | 7 | 1 | 8 | ✔️ |
H | 7 | 7 | 6 | 1 | 7 | ✔️ |
O | 1 | 1 | 1 | 1 | ✔️ | |
N | 1 | 1 | 1 | 1 | ✔️ |
The number of atoms of each element on both sides of C6H5CHOHCN = C6H5CHO + HCN is equal which means that the equation is already balanced and no additional work is needed.
