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.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.
