Answer:
The answer to your question is Propane
Step-by-step explanation:
Data
mass of Propane = 3 g
mass of Oxygen = 10 g
limiting reactant = ?
Balanced chemical reaction
C₃H₈ + O₂ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the reactants
C₃H₈ = (12 x 3) + (8 x 1) = 36 + 8 = 44 g
O₂ = 16 x 2 = 32 g
2.- Calculate the theoretical yield C₃H₈ / O₂ = 44/32 = 1.375
3.- Calculate the experimental yield C₃H₈/O₂ = 3/10 = 0.3
4.- Conclusion
The limiting reactant is Propane because the experimental yield was lower than the theoretical yield.
