Single-Displacement

Single-Displacement is when a element is substituted out of a compound for a more reactive element. An example of this is: AB + C ---> CB + A

A real life equation for this could be; Sodium reacts with Water to form Sodium Hydroxide and Hydrogen gas. The actual equation for that looks like this:

Na + H2O ---> NaOH + H2

Now we need to balance the equation!!!

Na + H20 ---> NaOH + H2

The first thing we need to do is place a "2" in front of the "Na" on the right and the "Na" on the left:

2Na + H2O ---> 2NaOH + H2

Now we have the sodium atoms but we still need to balance the rest, to balance the rest of the equation we need to put a "2" in front of the "H" on the left. Making the final equation appear as such:

2Na + H2O ---> 2NaOH + H2
