1. Write the Balanced Chemical Equation:
S + Cl₂ → S₂Cl₂
2. Convert Masses to Moles:
* Sulfur (S):
* Molar mass of S = 32.06 g/mol
* Moles of S = 200.2 g / 32.06 g/mol = 6.24 mol
* Chlorine (Cl₂):
* Molar mass of Cl₂ = 70.90 g/mol
* Moles of Cl₂ = 100.3 g / 70.90 g/mol = 1.41 mol
3. Determine the Mole Ratio from the Balanced Equation:
The balanced equation shows a 1:1 mole ratio between sulfur (S) and chlorine (Cl₂). This means for every 1 mole of S, you need 1 mole of Cl₂ to react completely.
4. Identify the Limiting Reactant:
* Sulfur: You have 6.24 moles of S.
* Chlorine: You have 1.41 moles of Cl₂.
Since you have less chlorine (1.41 moles) than sulfur (6.24 moles), chlorine is the limiting reactant. You don't have enough chlorine to react completely with all the sulfur.
Therefore, chlorine (Cl₂) is the limiting reactant.
