Solid calcium reacts with chlorine gas to form solid calcium chloride . write a balanced chemical equation for this reaction.

The balanced chemical equation is:

+ ⇒

Explanation:

Lavoisier was the first scientist to formulate the Conservation of mass that says “Nothing is lost, nothing is created, everything is transformed.” So, to balance this equation the number of atoms need to be the same in each side of the equation (reagents --- products). So, in the reagents there is one calcium (Ca) atom and in the product there is one Ca atom. Therefore, the calcium is balanced.  

To balance the chlorine (Cl) is used the same method. So, in the reagents there are two Cl atoms, and in the product there are two Cl atoms.
