What: Is A Balanced Chemical Equation

A balanced chemical equation is a symbolic representation of a chemical reaction where the total number of atoms for each element is exactly the same on both the reactant and product sides . Licensed by Google Why Does It Need to Be Balanced?

). These tell you how many molecules of that substance are involved. You balance equations by adjusting these numbers. A Quick Example: Making Water If you look at the raw reaction for making water:

: Add numbers in front of formulas to equalize the atom counts. It’s often easiest to save Hydrogen and Oxygen for last. what is a balanced chemical equation

2H2+O2→2H2O2 cap H sub 2 plus cap O sub 2 right arrow 2 cap H sub 2 cap O

: List how many atoms of each element are on the reactant (left) and product (right) sides. A balanced chemical equation is a symbolic representation

To balance an equation, you need to understand two types of numbers:

Now, there are 4 Hydrogen atoms and 2 Oxygen atoms on both sides. The "account books" are closed, and the mass is conserved! 3 Steps to Balance Any Equation These tell you how many molecules of that

: Every time you add a coefficient, recount all atoms to ensure you didn't accidentally unbalance another element.
