Answer:
0.70 moles of C₂H₂ are required to produced 0.70 moles of water
Step-by-step explanation:
Given data:
Moles of water produced = 0.70 mol
Moles of C₂H₂ required = ?
Solution:
Chemical equation:
C₂H₂ + O₂ → H₂O + CO₂
Balanced chemical equation:
2C₂H₂ + 5O₂ → 2H₂O + 4CO₂
Now we will compare the moles of water with C₂H₂.
H₂O : C₂H₂
2 ; 2
0.70 : 0.70
So 0.70 moles of C₂H₂ are required to produced 0.70 moles of water.
