Using these tables to help you memmorizing the final products.

Use these tables to check with the chemical reactions you learn, then you will see some patterns.

For example, when Carbon meets with oxygen, then it is oxidated. So there are only two options: CO and CO2. Since CO is lower in the table, then it is easy to guess that when there is not enough oxygen, then it will give CO; and enough oxygen will give CO2. When it is dissolved into water, then what will be found? A complex picture can be found in Nitrogen, but the table will help you to see how the products are related.
