Write the equation of lime n balance it!

To write the equation of lime (calcium oxide) and balance it, we first need to understand the chemical formula and the reaction involved. The chemical formula for lime is CaO.

The reaction of lime (CaO) with water (H2O) produces calcium hydroxide (Ca(OH)2). The balanced equation for this reaction is as follows:

CaO + H2O → Ca(OH)2

Now, let's balance the equation step by step:

1. Count the number of atoms for each element on both sides of the equation:
On the left side: 1 Ca, 1 O (from CaO)
On the right side: 1 Ca, 2 H, 2 O (from Ca(OH)2)

2. Balance the calcium (Ca) atoms by adding a coefficient of '1' in front of CaO:
CaO + H2O → Ca(OH)2

3. Balance the hydrogen (H) atoms by adding a coefficient of '2' in front of H2O:
CaO + 2H2O → Ca(OH)2

4. Balance the oxygen (O) atoms by adding a coefficient of '1' in front of Ca(OH)2:
CaO + 2H2O → Ca(OH)2

Finally, the balanced equation for the reaction of lime with water is:
CaO + 2H2O → Ca(OH)2
