Explanation:
The reaction of calcium and sodium chloride would yield to calcium chloride and sodium metal. It would be expressed as:
Ca + NaCl = CaCl2 + Na
To have the complete balanced reaction, it should be balanced where the number of each atom in the reactant side and the product side would be equal. The balanced chemical reaction would be:
Ca + 2NaCl = CaCl2 + 2Na
As we can see we have 1 calcium atom in each side, 2 sodium atom and 2 chlorine atoms in each side. This reaction is an example of a single displacement reaction where calcium displaces sodium and bonding with the chloride ion forming another salt.
