Questions and Answers

Why is it more appropriate to write the redox reaction (a) as 6CO2(g) + 12H2O(l) ® C6H12O6(aq) + 6H2O(l) + 6O2(g)?

  • To ensure mass balance in the reaction
  • To follow the law of conservation of energy
  • To account for the total number of water molecules produced
  • To balance the oxygen atoms on both sides of the equation (correct)

    • In the compound AgF2, why does it act as a very strong oxidizing agent?

  • Due to the high electronegativity of silver
  • Presence of highly electronegative fluorine atoms
  • AgF2 readily accepts electrons to achieve a stable configuration (correct)
  • AgF2 readily donates electrons to form stable compounds

    • When an oxidizing agent reacts with a reducing agent, what determines the oxidation state of the products?

  • The concentration of the reactants
  • The temperature at which the reaction occurs
  • The amount of excess reducing or oxidizing agent present (correct)
  • The type of solvent used
