To balance the chemical equation for the reaction between calcium and water, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Unbalanced Equation

The unbalanced equation is:

Ca + H₂O → Ca(OH)₂ + H₂

Balancing Steps

  • Start with calcium (Ca): There is 1 Ca atom on both sides.
  • Next, look at hydrogen (H): There are 2 H atoms in H₂O and 2 in Ca(OH)₂, so they are balanced.
  • Finally, check oxygen (O): There are 2 O atoms in Ca(OH)₂ and 1 in H₂O. To balance, we need to adjust the water molecule.

Final Balanced Equation

The balanced equation is:

Ca + 2 H₂O → Ca(OH)₂ + H₂

This shows that one calcium atom reacts with two water molecules to produce one calcium hydroxide molecule and one hydrogen molecule.
