Answer:
Percent yield of reaction is<em> 150%.</em>
Explanation:
Given data:
Percent yield = ?
Actual yield of SO₃ = 586.0 g
Mass of SO₂ = 705.0 g
Mass of O₂ = 80.0 g
Solution:
Chemical equation:
2SO₂ + O₂ → 2SO₃
Number of moles of SO₂:
Number of moles = mass/ molar mass
Number of moles = 586.0 g/ 64.1 g/mol
Number of moles = 9.1 mol
Number of moles of O₂:
Number of moles = mass/ molar mass
Number of moles = 80.0 g/ 32g/mol
Number of moles = 2.5 mol
Now we will compare the mole of SO₃ with O₂ and SO₂.
SO₂ : SO₃
2 : 2
9.1 : 9.1
O₂ : SO₃
1 : 2
2.5 : 2×2.5 = 5
The number of moles of SO₃ produced by oxygen are less it will limiting reactant.
Theoretical yield of SO₃:
Mass = number of moles × molar mass
Mass = 5 mol × 80.1 g/mol
Mass = 400.5 g
Percent yield of reaction:
Percent yield = actual yield / theoretical yield × 100
Percent yield = 586.0 g/ 400.5 g× 100
Percent yield = 1.5× 100
Percent yield = 150%

Answer:
092) Icosane
093) Ethene
Explanation:
092) The given compounds are;
Decane C₁₀H₂₂; Viscosity = 0.850 mPa·s (25°C)
Ethene C₂H₄ (gas); Viscocity ≈ 0.01038 m
Icosane C₂₀H₄₂; Solid at room temperature
Methane CH₄; gas at room temperature
The viscosity of the given carbon and hydrogen compounds is observed to increase with their molar masses
Therefore, icosane, which is a solid at room temperature, has the highest viscosity (resistance to deformation) out of the given compounds
093) Polymers are made from monomer alkene units, therefore, ethene, which is the only alkene among the given compounds can be used to produce a polymer
Polyethene is formed by the polymerization of ethene whereby molecules of ethene are joined together to form poly(ethene)
