This answer is true because it's t same amount
An average quality lawn captures 4 times the carbon output of a typical gasoline-powered mower.
Answer: Heterogeneous type of mixture.
Explanation:
This type of mixture are easily be seen and one may need a microscope sometimes. This category includes the suspensions where visible particles settles.
Answer A)
1. Ne will have 10 protons and the charge of protons is positive.
2. Ne will have 10 neutrons and there is no charge on the neutrons.
3. Ne has 10 electrons and the electrons have a negative charge.
4. Atomic number of Ne is 10.
5. Atomic mass of Ne is 20.1797 u.
6. Name of the atom is Neon.
Answer B)
1. Hydrogen has no neutrons.
2. Atomic mass of carbon is 12 u.
3. Calcium has 20 protons.
4. Fluorine has 10 neutrons.
5. Potassium has 20 neutrons.
6. Oxygen has 8 protons.
Protons identifies an atom.
The Lewis dot structure of Mg²⁺ is shown in the picture attached.
In Mg atom, the outermost orbit has 2 electrons.
The atom has the ability to lose its 2 electrons to become Mg²⁺
The Mg²⁺ ion have completed its vacancy in the second orbit having 8 electrons.
Therefore, the valency of Mg becomes 2+ as it loses its electron.
