What should we do with the CO2?

1 answer:

6 0

Answer:

The carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels.

Identify the species that was reduced in the titration reaction. Justify answer in terms of oxidation number 6h+(aq)+2mno4−(aq)+

egoroff_w [7]

Answer:

Explanation:

Reaction given

6 H⁺ + 2 MnO₄⁻ + 5 (COOH)₂ = 10CO₂ +8H₂O + 2 Mn⁺²

Oxidation number of Mn in MnO₄⁻

= x - 4 x 2 = -1

x = 8 -1

+ 7

Oxidation no of Mn in Mn⁺² = +2

So its oxidation no is decreased from + 7 to + 2 . Hence it is reduced.
