Chemical Properties of Matter

They are the properties of matter that describe how substances engage in chemical reactions.

During a chemical reaction, a substance changes to another substance.​

​

​Chemical Properties

​

it is the degree to which a chemical substance can cause injury to an organism.

Toxic substances can damage organ systems.

Some chemicals can injure upon contact, while some are carried by the blood.​

Some chemicals only affect certain organs.

​

​

Toxicity

It is the level of acid present in substances.

There are useful acids like those found in your body.

Too much acid in your stomach can hurt you.

​Pollution can cause acid rain (nitric and sulfuric acid).

​

Acidity

It is the ability of matter to react chemically with other substances.

It is also the rate at which a chemical reaction occurs.

​

​

Reactivity

​

It is how easily a substance will ignite or burn.

It is important to consider combustibility when using materials for construction.

Noncombustible materials are those substances that do not easily catch fire.​

​

​

​Combustibility

It is the ability of a substance to ignite or catch fire.

Combustion - the point where a material ignites.

Flammable liquids like gasoline can be used as fuel.​

​Flammability

Properties of Materials

It is important to know the properties of materials so we can discover ways to use them.

Discovering new substances help us make our lives easier.

We should know the properties of substances so we can avoid their harmful effects.​
