I already learned this last year.
Answer:
A. Empirical formula => SiCl₂I₂
B. Molecular formula = SiCl₂I₂
Explanation:
From the question given above, the following data were:
Silicone (Si) = 7.962 %
Chlorine (Cl) = 20.10 %
Iodine (I) = 71.94 %
Molar mass of compound = 352.8 g/mol
Empirical formula =?
Molecular formula =?
A. Determination of the empirical formula of the compound.
Si = 7.962 %
Cl = 20.10 %
I = 71.94 %
Divide by their molar mass
Si = 7.962 / 28 = 0.284
Cl = 20.10 / 35.5 = 0.566
I = 71.94 / 127 = 0.566
Divide by the smallest
Si = 0.284 / 0.284 = 1
Cl = 0.566 / 0.284 = 2
I = 0.566 / 0.284 = 2
Empirical formula => SiCl₂I₂
B. Determination of the molecular formula of the compound.
Empirical formula => SiCl₂I₂
Molar mass of compound = 352.8 g/mol
Molecular formula =?
Molecular formula = [SiCl₂I₂]ₙ
[SiCl₂I₂]ₙ = 352.8
[28 + (2×35.5) + (2×127)]n = 352.8
[28 + 71 + 254]n = 352.8
353n = 352.8
Divide both side by 353
n = 352.8 / 353
n = 1
Molecular formula = [SiCl₂I₂]ₙ
Molecular formula = [SiCl₂I₂]₁
Molecular formula = SiCl₂I₂
Elemental sulfur occurs as octatomic molecules, 63.2 g F2 are needed to react completely with 17.8 g S8 to produce SF6 .
<h3>What is octatomic molecules?</h3>
When stable under normal temperature and pressure circumstances, an octatomic element is a chemical element that has eight atoms arranged in a group. Sulfur, symbol S8, is the classic example, but red selenium is also an octatomic element that is stable at ambient temperature.
A molecule with eight sulfur atoms has a puckered ring or crown structure. Sulfur is in an octet state when it contains two more electrons than the six in its outermost shell. Sulfur has an atomic number of 16 and an electrical configuration of 2, 8, 6.
Other elements (S, Se, and Te) exist as octatomic solids while oxygen is a diatomic gas at normal temperature.
