How many moles of water are produced if 5.43 mol PbO2 are consumed

Question

Prof. Carmelo Hilpert · Accepted Answer

10.86 molesExplanation: For the given chemical reaction. 2 moles of lead combines with 2 moles of lead oxide and 2 moles of sulphuric acid to produce 2 moles of lead sulphate and 2 moles of water.1 mole of lead oxide produces 2 moles of waterThus 5.43 moles of lead oxide produces = moles of water

Prof. Carmelo Hilpert · Answer

10.9 mol.Explanation:To understand how to solve this problem, we must mention the reaction equation where water produced from PbO₂.Pb + PbO₂ + 2H₂SO₄ → 2PbSO₄ + 2H₂ONow, it is a stichiometric oriented problem, that 1 mole of PbO₂ produces 2 moles of H₂O.Using cross multiplication:1.0 mole of PbO₂ → 2.0 moles of H₂O5.43 moles of PbO₂ → ??? moles of waterThe moles of water produced = (5.43 x 2.0) = 10.86 moles ≅ 10.9 moles.

10.86 moles of water are producedFurther explanationA reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.ReactionPb + PbO₂ + 2H₂SO₄ ⇒ 2PbSO₄ + 2H₂O ( a car battery reaction)From the equation : mol ratio PbO₂ : H₂O = 1 : 2⇒ 1 mol PbO₂ produces 2 mol H₂Oso for 5.43 mol PbO₂ consumed,  mol H₂O :

5.43 times 2 = 10.8610.9 is your answer.

Prof. Carmelo Hilpert · Answer

The correct answer is 10.86 moles. It is a stoichiometry based problem,  One can solve this by just knowing the balanced chemical equation. The reaction where PbO2 is used and water is generated is:  Pb + PbO₂ + 2H₂SO₄ → 2PbSO₄ + 2H₂OThe mentioned reaction is witnessed in the lead storage battery.  Therefore, here as per the balanced equation one mole of PbO₂ is consumed providing two moles of water. So, for 5.43 moles of PbO₂, we will get,  2 × 5.43 moles of water = 10.86 moles.

Prof. Carmelo Hilpert · Answer

this is a stoichiometry based problemWe can solve this by just knowing the balanced chemical equation.The reaction where PbO2 is used and water is produced isPb + PbO2 + 2H2SO4 > 2PbSO4 + 2H2OThis is reaction in lead storage batteryso here as per balanced equation one mole of PbO2 is consumed giving two moles of waterso if 5.43 moles of PbO2 we will get = 2 X 5.43 moles of water = 10.86 moles

Prof. Carmelo Hilpert · Answer

It has to be understood that 2 moles of oxygen are there in each mole of PbO2. Then it has to be calculated for 2 moles of oxygen.Amount of oxygen = 2 * 5.43 moles                              = 10.86 molesNow it is also a fact that each mole of H2O contains 1 mole of oxygen. Then it can be easily concluded that 10.86 moles of water will be produced. I hope the procedure is clear enough for you to understand.
