Find out the properties, formal charge, and electronic configuration of H2SO4 and its Lewis structure.43 mol PbO2 are consumed?, The fuel … Study with Quizlet and memorize flashcards containing terms like Which one of the following equations is properly balanced? Sn + 4HNO3 → SnO2 + 4NO2 + 2H2O 2Na2SO4 + 3Bi(NO3)3 → Bi2(SO4)3 + 9NaNO3 NH4NO3 → 2H2O + N2 CH3CHO + 3O2 → 2CO2 + 2H2O Na2CO3 + 2H2SO4 → Na2SO4 + 2H2O + CO2, Which of the following … Study with Quizlet and memorize flashcards containing terms like A car battery produces electrical energy with the following chemical reaction. Pb + PbO2 + 2H2SO4 = 2PbSO4 + 2H2O is a redox reaction where Pb is oxidized and Pb is reduced.05 V. 3. E) 1. moles 2H2SO4 to grams. This means that for ever 1 mole of PbO2 consumed, 2 moles of water is formed as product. Therefore, sulfur is the element that is reduced in this reaction. Since there is an equal number of each element in the reactants and products of 2H2SO4 + Mg = MgSO4 + 2H2O + SO2, the equation is balanced Your answer should have six terms. First, compute the number of each atom in *2H 2 SO 4: H: 4, S: 2, O: 8. 2. The mole ratio of PbO2 to water is 1:2.
