Answer:
The peak at mass 100 with a 8% relative abundance is the molecular ion peak
Explanation:
Molecular ion peak has the highest charge to mass ratio,
Mass of 100 is same as mass to charge ratio =100
Answer:
ΔrxnHº =-1,124.3 kJ
Explanation:
To solve this question we first need to search for the enthalpies of formation of reactants and products and calculate the change in enthalpy of reaction utilizing the equation
ΔrxnHº = ∑ νΔfHº reactants - Σ νΔfHº products
where ν is the stoichiometric coefficient of the compound in the balanced equation .
ΔfHº H₂S(g) = -20.50 kJmol⁻¹
ΔfHº 0₂(g) = 0 ( O₂ is in standard state )
ΔfHº H₂O(l) = -285.8 kJmol⁻¹
ΔfHº SO₂(g) = -296.84 kJmol⁻¹
ΔrxnHº = [2 x -285.8 + 2 x -296.84] - [2 x -20.50]
= - 1,124.3 kJ
