Answer: The chemical formula of a zeolite is Na2. Al2O3. nSiO2 Permutite is an artifical zeolite used for softening of water. Through ion-exchange process, here cation-anion exchange chamber is used to obtain pure water. In calgon's process sodium hexa meta phosphate is used to soften the water.
Explanation:
Answer: Destruction of the ozone
Explanation: Some of the he most common refrigerants used for air conditioning is chloroflurocarbons and hydroflurocarbon that can deplete the ozone layer that is a protective covering.
This covering filters the harmful rays of the sun that is harmful for the human beings and animals on the earth. The coolants contains chlorine which impacts the ozone and cause depletion.
Peripheral
vision is a part of sight that happens outside the very middle of gaze. There is a general
set of non-middle points in the <span>sight field that is part in the idea of peripheral vision. Mostly,
peripheral vision is used when playing sports namely basketball and volleyball
because peripheral vision is also known as side view, we can see the object or
person in the side without actually looking at them. </span>
<span>Ionization energy (IE) is the amount of energy required to remove an electron.
If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).</span>
