Whicwhich of the following is an oxidation-reduction reaction?
so2(g) + h2o(l) mc010-1.jpg h2so3(aq)
caco3(s) mc010-2.jpg cao(s) + co2(g)
ca(oh)2(s) + h2co3(l) mc010-3.jpg caco3(aq) + 2h2o(l)
c6h12o6(s) + 6o2(g) mc010-4.jpg 6co2(g) + 6h2o(l)h of the following is an oxidation-reduction reaction?

Answer is: C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l).

Balanced chemical reaction for cellular respiration (convert biochemical energy):  

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l).

In this reaction carbon is oxidized (lost electrons) and oxygen is reduced from oxidation number 0 to oxidation number -2 (gain electrons).

In other example atoms do not change their oxidation numbers.

Glucose (C₆H₁₂O₆) is a chemical compound composed of six carbon atoms, twelve hydrogen atoms and six oxygen atoms.

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
