• Respiration is one of the most common chemical reactions on earth. It includes the oxidation of glucose
(CsH1206) into carbon dioxide and water with the release
of approximately 2900 kJ of energy when one mole of
glucose is broken down according to the following
balanced equation:
C6H12O6 + 602 → 6CO2 + 6H2O + 2900 kJ mol-1
Then, upon the reaction of 25 grams of glucose with 40
grams of oxygen: 0,
- What is the limiting reactant?
- What mass of carbon dioxide formed?
- What is the weight left of excess reactant?
How much energy is released upon reaction of the
given amounts of glucose and oxygen?
(Atomic weights = 12.9 = 16 and H = 1 g/mol)​

Answer:

5.6⋅10−^19  j

do you need the explaination?

What are the statements?

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
