Hello,
Aluminium is a metal with 13 as its atomic number, in such a way, one could foresee the Lewis structure via its electron configuration:
Al^{13}: 1s^22s^22p^63s^23p^1
It is seen that in its last level, 3, there are three electrons, two from 3s^2 and one from 3p^1, in such a way one states that aluminium has three valence electrons which are equal to the electrons at its outer shell. The Lewis representation for aluminium is shown on the attached picture.

1) Balanced chemical equation
8H2S +4O2 ---> S8 + 8H2O
2) Molar ratios
8 mol H2S : 4 mol O2 : 1 mol S8
3) Convert 50.0 grams of H2S into moles
moles = mass in grams / molar mass
molar mass H2S = 2*1g/mol + 32.1 g/mol = 34.1 g/mol
moles = 50.0 g / 34.1 g/mol = 1.466 moles H2S
4) Convert 60.0 g of O2 into moles
molar mass O2 = 2*16g/mol = 32.0g/mol
moles = 60.0g / 32.0 g = 1.875 moles O2
5) State limiting reagent
Theoretical ratio: 8 mol H2S / 4 mol O2 = 8/4 = 2/1 = 2
Actual ratio 1.466 mol H2S / 1.875 mol O2 < 2
=> H2S is the limiting reagent (it is consumed completely whilce some O2 remains unreacted).
6) Determine the moles of S8 produced from 1.466 moles H2S
1 mol S8 / 8 mol H2S * 1.466 mol H2S = 0.18325 mol S8
7) Convert 0.18325 mol S8 to mass
mass = number of moles * molar mass
molar mass S8 = 8 mol * 32.1g/mol = 256.8 g/mol
mass = 0.18325 mol * 256.8 g/mol = 47.1 grams
Answer: 47.1 g
We know, Kinetic energy (movement of the particle) is directly proportional to the temperature of the object. When you decrease the temperature, it's movement will also decrease and object particles move slower.
In short, Your Answer would be Option B
Hope this helps!
Answer:
The egg is changed from liquid to soli
Explanation:
The law of conservation of mass states that "Matter/mass can neither be created nor destroyed but can be converted from one form to another".
Inside of the Egg is liquid in nature and during the process of cooking the egg the liquid changes to solid.
