Different Types of Chemical Equation Part II

Hi, We are back.

Today we are going to talk about the other types of chemical equation:

• Double replacement
• Combustion
• Neutralization

Double replacement:

Before we talk about chemistry stuff, imagine a school prom. (even though there is practically no dances in Magee...)

Let's say that Bill and Becca are partners and Jack and Jill are partners.

After few rounds of dancing, they decide to switch partners

So Bill dances with Jill and Jack dances with Becca

This situation basically outlines the double replacement reaction in chemistry.

The general formula is:

AB + CD → AC + BD

Note:

There are situations in double replacement where there is a reaction or not.

The key is very simple:

If there is a change in state, (e.g. aqueous to solid) there is a reaction. If there is no change, there is no reaction.

Use the table of solubility determine the states

Next:

Combustion:

This is a reaction where burning with oxygen is involved. In my opinion, I think that this is the easiest.

Basically, when the reactants are organic (carbon, oxygen and hydrogen), the outcome will always be

carbon dioxide and water.

So the formula is

AB + O2 → AO + BO

Lastly,

Neutralization:

This is a special type of double replacement. This deals with only acids and bases.

This is also very simple,

the product will be water and the aqueous solution from metal and non-metal from the acid and base.

So the formula becomes:

HA + BOH → H2O + BA

H and OH are from acids and bases

This is it for today.

Stay tuned for more :D
