Container A has a latent heat of vaporization of 732 J/g.
Container B has a latent heat of vaporization of 841 J/g.
Latent heat of vaporization refers to the vaporizing a liquid or a solid or condensing a vapour.
This means that Container A boils first because it has lower latent heat of vaporization.
As you heat a solid, turning it into a gas, the kinetic energy of the molecules are increased to a point where there are no forces of attraction between the molecules. Thus, Container B will freeze faster than Container A

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 mass of one mole of an element or a compound, called the molar mass, can be found from a periodic table.
- The unit of molar mass is g/mol.
=> 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.

First we find the molar mass of Mg(OH)₂
Mg + 2O + 2H = 24.31 + 2×16 + 2×1.01 = 58.33 gmol⁻¹.
Then find the number of moles: n = m/M = 3.7 / 58.33 = 0.0634 mol
So now we know that 0.0634 mol are produced per litre of sea water.
Let the amount of water in litres needed to evapourate to produce 5.00 moles be x.
We can express this as a ratio.
0.0634 mol / 1 l = 5 mol / x l.
Solve for x by cross-multiplication:
0.0634x = 5×1
x = 5/0.0634 = 78.8 litres. (rounded to three significant figures)

Answer: Four hybridized orbitals will formed when one s-orbital and three p-orbitals combines.
Explanation:
- When ever one s-orbital combines with three p-orbitals it gives four
hybridized orbitals.
- In which there is 25% of s character and 75% of p character.
- The shape of the
it's just adding the number of s and p together
example of sp3 hybridization = CH4
with 1 s orbital of H and 3 p orbital of C

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.
