## What are the 3 rules for balancing equations?

There are essentially three steps to the process:

- Write the unbalanced equation. Chemical formulas of reactants are listed on the lefthand side of the equation.
- Balance the equation.
- Indicate the states of matter of the reactants and products.

## What are some strategies you can use to balance chemical equations?

Strategies for Balancing Chemical Equations 1. Balance the simplest formula/element last. 2. Use the Least Common Multiple between two numbers.

**How do you balance chemical equations examples?**

Examples of Balancing Chemical Equations

- Example 1. C5H12 + O2 —> CO2 + H2O.
- Example 2. Zn + HCl —> ZnCl2 + H2
- Example 3. Ca(OH)2 + H3PO4 —> Ca3(PO4)2 + H2O.
- Example 4. FeCl3 + NH4OH —> Fe(OH)3 + NH4Cl.
- Example 5. S8 + F2 —> SF6
- Example 6. C2H6 + O2 —> CO2 + H2O.
- Example 7. Al2(CO3)3 + H3PO4 —> AlPO4 + CO2 + H2O.

**What element do you start with when balancing chemical equations?**

If possible, start with an element found in one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation.

### Which elements should you balance first?

Basically, you look at how many atoms you have on each side of the equation and add coefficients to the molecules to balance out the number of atoms. Balance atoms present in a single molecule of reactant and product first. Balance any oxygen or hydrogen atoms last.

### What is the most important information that can be gained from a balanced chemical equation?

And, if the equation is balanced: The coefficient numbers in the equation show the number of molecules, formula units, or atoms of the species involved in the reaction. The coefficients also equal the number of moles of each reactant and product.
