The liters of sea water must evaporate to produce 5.00 moles of magnesium hydroxide - 78.8 litres.
A mole is a special unit of quantity of a chemical species that contains exactly Avogadro's number of particles.
=> the molar mass of Mg(OH)₂
Mg + 2O + 2H
= (24.31) + (2×16) + (2×1.01)
= 58.33 gmol⁻¹.
then,
=> the number of moles:
n = m/M
=
= 0.0634 mol
=> the amount of water in liters needed to evapourate to produce 5.00 moles:
=>
=> 0.0634x = 5×1
=>
=> x = 78.8 litres.
Thus, the liters of sea water must evaporate to produce 5.00 moles of magnesium hydroxide - 78.8 litres.

Answer: Four hybridized orbitals will formed when one s-orbital and three p-orbitals combines.
Explanation:
When two fluorine atoms react to produce a fluorine molecule, Energy is released as a bond is formed. The answer is number 4. IT takes energy to form a bond from two atoms that is why energy is releases after the bond is formed.
Answer: Option (d) is the correct answer.
Explanation:
It is known that sea water contains a large amount of common salt, that is, sodium chloride (NaCl). This salt is basic in nature.
Since, it is also known that species which have pH equals to 7 are basic in nature. Species which have pH less than 7 are acidic in nature and species which have pH greater than 7 are basic in nature.
Hence, due to the presence of common salt in sea water its surface is basic in nature.
Therefore, we can conclude that the normal pH of surface sea water is 9.0.
