Explanation:
Magma convection is the primary driving mechanism by which geothermal energy is brought to the earth.
Geothermal energy is energy from deep within earth has been brought close to crustal levels.
They are usually sourced from areas in which a body of magma is appreciably close to the surface or where the mantle is close up.
- Mantle convection is movement of magma within the region of the earth's mantle.
- In this process, hot magma rises up close to the surface and cold ones sinks further deep into the mantle.
- As hot magma rises in the mantle, it is brought close to the surface and crustal levels.
- Where the crust is thin, the heat from the ensuing magma can be felt more close up
- Cracks in the overlying lithosphere can bring these magma up ensuring a continuous supply of this hot mantle materials.

When the concentration is expressed in ppm, that means parts per million. It is also equivalent to mg/L. For this problem, we do stoichiometric calculations. We manipulate the units by cancelling like units if they appear in the numerator and denominator side until we come with the amount of solid Ca(OCl)2 needed. The solution is as follows:
40 mg/L * (1 L/1000 mL) * 50 mL * (1 g/1000 mg) * (1 mol OCl⁻/51.452 g) * (1 mol Ca(OCl)₂/ 2 mol OCl⁻) * (142.983 g Ca(OCl)₂/mol) * 0.95 = 2.64×10⁻3 g or 2.64 mg.
Therefore, you would need 2.64 mg of solid Ca(OCl)₂.
Seven diatomic elements are H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂.
<h3>Which are diatomic molecules?</h3>
Diatomic molecules are those molecules in which two atoms of same elements are present, and they are combined to attain the stability.
The seven diatomic molecules which are exist in the chemistry are:
- Hydrogen gas (H₂)
- Chlorine gas (Cl₂)
- Nitrogen gas (N₂)
- Fluorine gas (F₂)
- Bromine gas (Br₂)
- Iodine gas (I₂)
- Oxygen gas (O₂)
Hence H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂ are 7 diatomic molecules.
