Answer:
d. None of the above
Explanation:
Desalination is the process of removing some mineral salts from water or soil thereby making a water more fresh and the soil less filled with mineral salts. Salty water can be desalinated by doing away with their salts leaving behind a water that would be more suitable for certain needs. Desalinated water can be used domestically, industrially and also for agriculture.
Soils that have been desalinized can be more suitable to plant some special types of crops that would not thrive where some certain mineral salts occur in excess.
Desalination is an expensive process.
Water reclamation is the reuse of waste to serve new needs. It involves recycling of waste or polluted water into a more fresher water. Reclaimed water can also be used for agricultural, domestic and industrial purposes.
Desalination is a method that can be used to reclaim water. It is also an expensive process.
Desalination recharges aquifers: Desalination is an artifical process and would not add back to the ground water storage.
Desalination provides water suitable for drinking: water reclamation also provides suitable water for drinking.

Explanation:
Answer:
1. Sp^3; Sp.
2. Isomers.
3. Weaker.
4. Atomic; hybrid.
5. Pi.
6. Electronegativity.
7. Resonance structures.
8. Sigma.
Explanation:
1. A tetrahedral carbon is Sp^3 hybridized while a linear carbon is Sp hybridized. A tetrahedral carbon typically comprises of four bonds that are 109. 5° apart while a linear carbon atom comprises of two (2) bonds that are 180° apart.
2. Two different compounds that have the same molecular formula are known as isomer. For example Butane and Isobutane, Methoxyethane and Propanol have the same molecular formula (numbers of hydrogen and carbon atoms) but different structural formula.
3. Pi (π) bonds are generally weaker than sigma (σ) bonds. This is because the orbital paths of Pi bonds are parallel thereby causing an overlap.
4. Hybridization is the combination of two or more atomic orbitals to form the same number of hybrid orbitals, each having the same shape and energy.
5. A Pi bond is formed by side-by-side overlap of two p orbitals.
6. The electronegativity is a measure of an atom’s attraction for electrons in a bond and indicates how much a particular atom "wants" electrons.
7. Two Lewis structures that have the same atomic placement and σ structure but a different arrangement of π electrons are called resonance structures.
8. All single bonds are Sigma bonds.
The elements in each group have the same number of electrons in the outer orbital<span>. Those </span>outer<span> electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its </span>outer<span> shell.</span>
