Which of the following happens during a chemical change? Check all of the boxes that apply.
0 One atom or more changes into atoms of another element.
New substances with different properties are formed.
Solids, liquids, or gases may form.
Reaction mixtures always give off some heat.
Reaction mixtures always need to be heated.

E is wrong. Many reaction mixtures are so unstable that they must be cooled to prevent the reaction from going so fast that an explosion might result.

Good Luck!

During a chemical change, new substances with different properties are formed and solids, liquids, or gases may form.

Do chemical changes create new materials with new properties?

In a physical change, the appearance or type of story changes but the type of story in the object does not change. However, in chemical reactions, the substance of a substance changes, and at least one new substance with new characteristics is formed.

What is the process by which new substances are formed during chemical reactions?

Chemical changes occur when an element interacts with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are irreversible without other chemical reactions.
