H2+O2→H2Ocap H sub 2 plus cap O sub 2 right arrow cap H sub 2 cap O
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
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?
: The small numbers within a chemical formula (like the H2Ocap H sub 2 cap O
: The large numbers placed in front of a molecule (like the 2H2O2 cap H sub 2 cap O
: Every time you add a coefficient, recount all atoms to ensure you didn't accidentally unbalance another element.
