Single-Displacement

__**Single-Displacement**__

In this type of reaction, which is also known as a replacement reaction, one element replaces a similar element in a compound.

An example of this could be the equation: Sold iron and water vapor react to produce a solid of iron oxide and hydrogen gas.

To form it into a chemical equation, we must change its modern names into its chemical symbols. Iron= Fe Hydrogen=H Oxygen=O

To do this, look at the periodic table and match up modern names with their symbols. Fe(s)+H2O(g) à Fe3O4(s)+ H2(g) __1__ Fe __3__ __2__ H __2__ __1__ O __4__

Now we must balance the chemical equation! 3Fe(s)+4H2O(g) à Fe3O4(s)+4H2(g) __3__ Fe __3__ __8__ H __8__ __4__ O __4__

Hurray! The chemical equation is now balanced!
