Answer:
Therefore when 1.26 moles of H₂O is reacted 0.63 mole of O₂ are produced.
Explanation:
The required reaction is
H₂O → O₂+H₂
The reaction is not balance reaction. First we have to balance the reaction.
2H₂O → O₂+2H₂
From the above reaction we conclude that,
2 mole of H₂O produces 1 mole of O₂ and 2 moles of H₂.
∴When 2 mole of H₂O reacts then it produces 1 mole of O₂
1 mole of H₂O reacts then it produces mole of O₂.
1.26 mole of H₂O reacts then it produces mole of O₂.
=0.63 mole
Therefore when 1.26 moles of H₂O is reacted 0.63 mole of O₂ are produced.
