How do you balance #CaO + H_2O -> Ca(OH)_2#?

This one is simple because it is already balanced, which indicates that the number of atoms on the input (left side) and output (right side) of the arrow should be equal.

Simply type "balance" into this website's search bar to find a ton of examples of chemical reaction balancing exercises.

To balance the chemical equation CaO + H2O -> Ca(OH)2, follow these steps:

1. Write down the unbalanced equation: CaO + H2O -> Ca(OH)2.
2. Count the number of atoms of each element on both sides of the equation.
3. Start by balancing the atoms that appear only once on each side of the equation. In this case, Ca (calcium) appears once on each side.
4. Balance the oxygen atoms by adding coefficients in front of H2O and Ca(OH)2.
5. Balance the hydrogen atoms by adding coefficients in front of H2O.
6. Verify that all atoms are balanced. If not, adjust coefficients as needed until the equation is balanced.

The balanced equation for CaO + H2O -> Ca(OH)2 is: CaO + H2O -> Ca(OH)2.
