Answer:
near the equator where it's hot
I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once they are combined to form a mixture.
I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
Hope i helped, have a nice day.
The dark side your welcome
Answer:
H2
Explanation:
H (or hydrogen), being a halogen, as an atom, has 7 valence electrons. This means that it naturally bonds with another atom of the same isotope in order to reach the desired total of valence electrons: 8.
So... H+H = H2. EZ
Answer:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
Explanation:
Amino acids are organic molecules which base chemical structure is composed by:
- a carbon atom (C)
- a carboxyl group (-COOH)
- an amino group (-NH₂)
- a side chain- called R group- which varies in different amino acids. It can be composed by N, H, O, C and sometimes S.
According to this, the five chemical elements that are present in amino acids are:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
