Correct: ox: 2BrBr2 2e Incorrect ox: Br + 2e- B,2- re: 2a- a2 + 2e- ou are correct. ur receipt no. is 168-2447Previous Tries 14. Balance the cellular respiration equation: H2O And enter the total number of electrons transferred in this REDOX process: Submit AnrIncorrect. Tries 1/3 Previous Tries 15. Construct a galvanic cell with the following two half-reactions: Ca+2eCa Ed -2.76 v Cu+2eCu d0.34v Which of the following statements about this galvanic cell is FALSE: Incorrect Cu will be the electrode at the cathode Correct: The mass of the Ca electrode will increase during the course of the reaction Incorrect The potential of this cell (at standard conditions) l be 3.10 V Incorrect Electrons will flow from the Ca electrode toward the Cu electrode Incorrect Negatively charged ions will fhow from the salt bridge toward the anode ou are correct. ur receipt no. is 168-8066 Previous Tries 16. The reaction shown below is an unbalanced oxidation/reduction reaction: Mno (a)+ Br (a) Br (a)Explanation / Answer
(14) C6H12O6 + O2 ---------> CO2 + H2O
Balance all the atoms on both sides by using suitable coefficients,
Balanced equation is => C6H12O6 + 6O2 ---------> 6CO2 + 6H2O
each oxygen gains 2 e-s ,
So,
Total number of electrons transferred = 24 e-
