Step-by-step solution
6 stepsChemical equations represent chemical reactions. They show the reactants (starting materials) on the left and the products (substances formed) on the right, separated by an arrow (→). The equation must be balanced, meaning the number of atoms of each element is the same on both sides.
Here's an example: The reaction between hydrogen gas (H₂) and oxygen gas (O₂) to form water (H₂O).
Write the unbalanced equation
H₂ + O₂ → H₂O
Count the atoms of each element on both sides.
Left side: H = 2, O = 2
Right side: H = 2, O = 1Balance the oxygen atoms.
To get 2 oxygen atoms on the right, place a coefficient of 2 in front of H₂O.
H₂ + O₂ → 2H₂ORecount the atoms.
Left side: H = 2, O = 2
Right side: H = 4, O = 2Balance the hydrogen atoms.
To get 4 hydrogen atoms on the left, place a coefficient of 2 in front of H₂.
2H₂ + O₂ → 2H₂OFinal check.
Left side: H = 4, O = 2
Right side: H = 4, O = 2
The equation is now balanced.
