What are the 3 main parts of a chemical equation?
A chemical equation shows the starting compound(s)—the reactants— on the left and the final compound(s)—the products—on the right, separated by an arrow.
What are the main parts of a chemical reaction?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants , and the substances produced at the end of the reaction are known as the products.
What are 3 signs of a chemical reaction?
Some signs of a chemical change are a change in color and the formation of bubbles . The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.

What is the most powerful chemical reaction?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
What is the most important chemical in the world?
Sulfuric acid is the world’s most important industrial chemical! In North America we produce about 50 million tons a year, mostly by burning sulfur to form sulfur dioxide which is then reacted with water. Why do we need all that sulfuric acid? Primarily to produce fertilizer.
What are reaction types?
Basic chemical reactions can be grouped into categories based on the types of changes that are occuring during the reaction. There are five basic categories – synthesis, decomposition, combustion, single replacement, and double replacement .
What are the two parts of a chemical reaction *?
There are two parts of a chemical equation. The participating elements or molecules in a chemical reaction are called reactants and are represented on the left side of the arrow (→) . The compound that forms after the changes in the participating reactants are called products.
What are 4 examples of physical changes?
- Crushing a can.
- Melting an ice cube.
- Boiling water.
- Mixing sand and water.
- Breaking a glass.
- Dissolving sugar and water.
- Shredding paper.
- Chopping wood.
What is an example of color change?
Sometimes a change in color is simply the mixing of two colors and not due to a change in the composition of the substances used. For example, putting red food coloring and blue food coloring in a beaker of water results in purple water, but no chemical reaction has occurred.
What are the 7 signs of a chemical reaction?
- Gas Bubbles Appear. Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. ...
- Formation of a Precipitate. ...
- Color Change. ...
- Temperature Change. ...
- Production of Light. ...
- Volume Change. ...
- Change in Smell or Taste.
