Write a mechanism (using curved-arrow notation) for the deprotonation of tannins in base. use ar-oh as a generic form of a tannin and use sodium carbonate (na2co3) as the base. balance the chemical equation. comment on the aqueous solubilities of each species (assume that the tannin is insoluble in water initially)

Question 17 hydrogen is manufactured on an industrial scale by this sequence of reactions: +ch4gh2og ⇌ +cog3h2g k1 +cogh2og ⇌ +co2gh2g k2 the net reaction is: +ch4g2h2og ⇌ +co2g4h2g k write an equation that gives the overall equilibrium constant k in terms of the equilibrium constants k1 and k2. if you need to include any physical constants, be sure you use their standard symbols, which you'll find in the aleks calculator.
