Answer: A chemical reaction is the change of a substance into a new one that has a different chemical identity. In summary, a chemical reaction is a process that converts one or more substances to another substance. Chemical reactions start with reactants and convert them into products. Most chemical reactions inside living things are regulated by enzymes, which speed up chemical reactions.A chemical reaction is a process that changes or transforms one type of chemical into another. ... Life is the result of countless reactions happening all at the same time, most often between carbon, hydrogen, nitrogen, and oxygen atoms. Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
An electromagnetic wave such as x rays wave would be observed outer space between planets, where there is very little matte
an electromagnetic wave such as x rays
<u>Explanation:</u>
Electromagnetic waves are the waves it can be observed in the outer space between the planets, the other waves such as the sound waves are the mechanical waves, which need the medium for its propagation.
There is no medium between the planets so there is an empty space for the propagation. Hence the sound waves do not pass through the medium.
The mechanical wave can have the material for the propagation. The electromagnetic waves can be used to transport the energy from one form to another. It does not require the material medium.
C. Light energy from the Sun is converted into chemical energy in plants
I believe it is just 2 1/2 m.
