Identify the reactants and products in a chemical reaction.

Chemistry Anyone?

-What is Chemistry?

​
Chemistry is defined as the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

Driving Vehicles
Switching on and off lights
The use of paint
The use of thermometers​

How do we use Chemistry everyday?

Chemistry is concerned with properties of chemicals and with the changes chemicals can undergo. A Chemical is any substance that has a definite composition it's always made of the same stuff no matter where the chemical comes from. Some chemicals, such as water and carbon dioxide, exist naturally. Others, such as polyethylene, are manufactured. Others, such as aluminum, are taken from natural materials.

The Bradley Challenge:
​The next time your getting ready for school, look at the list of ingredients in your shampoo or toothpaste. You'll see an impressive list of chemicals. Without chemicals, you would have nothing to wear. The fibers of your clothing are made of chemicals that are either natural, such as cotton or wool. or synthetic, such as polyester. The air you breathe, the food you eat, and the eater you drink are made up of chemicals.

Propylene
Ammonia
Chlorine

Top Eight Chemicals Made in the United States

All matter is made of particles. The type and arrangement of the particles in a sample of matter determine the properties of the matter.

Physical States of Matter

Properties of the Physical States:
Solids have fixed volume and shape that result from the way their particales are arranged. The particles are held tightly together.
Liquids have fixed volume, but not a fixed shape. The particles in a liquid are not held together as strongly as those in a solid.
Gases have neither fixed volume nor fixed shape. Gas particles weakly attract one another and move independently at high speed. Gas Particles will fill any container they occupy as their particles move apart.

Matter Changes

​Physical and Chemical changes

Physical changes are changes in which the identity of a substance doesn't change. However, the arrangements, location, and speed of the particles that make up the substance may change. Changes of state are physical changes.

In a chemical change, the identities of substances change and new substances form.
