Answer: Atoms form chemical bonds to satisfy the<u> Octet</u> rule and to become <u>stable.</u>
Explanation:
The tendency of atoms to attempt to get a noble gas configuration that is eight valence electrons is said to be octet rule. This is done to attain noble gas configuration and stability.
In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.
For example : As we know that the sodium has one valence electron, so if giving it up then the result in the same electron configuration as the neon and chlorine has seven valence electrons, so if it takes one it will have eight and the result in the same electronic configuration as the argon which is stable.
The fossil fuels, CO2, greenhouse effect, and climate change are all things that are connected with each other and contribute for each successive one to occur. The fossil fuels are heavily used by the humans. Through their burning, the fossil fuels release lot of CO2 into the atmosphere. The CO2 is the most common greenhouse gas, thus it is a gas that manages to trap the heat into the atmosphere. So as the CO2 from the burning of the fossil fuels increases in the atmosphere, the greenhouse effect also increases. The greenhouse effect is the one that manages to keep the Earth warm, which is good, but it can also pass the limit and make the whole planet much warmer, resulting in rise of the sea levels because of the melting of the ice caps and glaciers. That will cause significant climate changes all over the globe because the sea currents will change, the atmosphere will keep more heat, and the water surface will increase.
The concentration in mol L-l (M) = 0.717

Given
12% solution of tetrahydrate magnesium chloride (MgCl₂)
Required
The concentration
Solution
Tetrahydrate magnesium chloride (MgCl₂)⇒MgCl₂.4H₂O
MW = Ar Mg+2. Ar Cl+8. Ar H + 4. Ar O
MW=24.31 + 2 x 35.45 + 8 x 1.01 + 4 x 16
MW=24.31+70.9+8.08+64
MW=167.29 g/mol
12% solution = 12 % m/v = 12 g in 100 ml solution
For 1 L solution :
The concentration in g/L = 120 g/L
