Free Chemistry Equation Balancer Online | Homeworkify
Balance any chemical equation online for free. Type your reaction or upload a photo, and Homeworkify adds the right coefficients and shows the fully balanced equation in seconds. No sign up needed.
What Our Free Chemistry Balancer Can Do
It does more than balance. It shows the coefficients and explains how each side is made equal.
Balances Any Equation
Enter an unbalanced reaction and get the correct coefficients on both sides.
Step-By-Step Working
See how the atoms are counted and matched, not just the final answer.
All Reaction Types
Synthesis, decomposition, combustion, replacement, acid base, and redox.
Balance From A Photo
Snap a picture of your equation and let the balancer read and solve it.
Instant Results
Get the balanced equation in seconds, any time of the day or night.
Free And No Sign Up
Balance as many equations as you need with no account and no fees.
Types Of Reactions You Can Balance
From simple synthesis to tricky redox, the balancer handles it.
Synthesis
Two or more reactants combine to form a single product.
Decomposition
A single compound breaks down into two or more products.
Combustion
A fuel reacts with oxygen to produce carbon dioxide and water.
Single Replacement
One element takes the place of another in a compound.
Double Replacement
Two compounds swap parts to form two new compounds.
Acid Base And Redox
Neutralization reactions and reactions that transfer electrons.
How To Balance An Equation
Three quick steps from an unbalanced reaction to a balanced one.
Enter Your Equation
Type your unbalanced equation into the box above, or upload a photo or PDF of it.
Let It Balance
The balancer counts the atoms on each side and adds the correct coefficients in seconds.
Check The Result
Read the balanced equation and the working, then copy or save it for your homework.
Example Balanced Equations
Here is the kind of clear, balanced result you can expect.
Synthesis
Balance: H2 + O2 → H2O
Balanced: 2H2 + O2 → 2H2O
Combustion
Balance: CH4 + O2 → CO2 + H2O
Balanced: CH4 + 2O2 → CO2 + 2H2O
Synthesis
Balance: N2 + H2 → NH3
Balanced: N2 + 3H2 → 2NH3
Oxidation
Balance: Fe + O2 → Fe2O3
Balanced: 4Fe + 3O2 → 2Fe2O3
