Asap
the reactants of two reactions are shown.
reaction 1: c and o2
reaction 2: k2so4 and cacl2
which reaction is likely to be a redox reaction?
a. only reaction 2, because potassium and calcium ions will interchange their positions

b. both, because the electrostatic charge on cations will change during each reaction

c. both, because the electrostatic charge on anions will change during each reaction

d. only reaction 1, because the charge of carbon changes during the reaction

Hey

The answer should be D

A

Explanation:

Carbon and oxygen reaction is never a redox reaction. Carbon burns in air and produce carbon dioxide if there is unlimited supply. In case limited supply carbon monoxide will be produced but that still is non-reversible reaction.

Potassium sulphate and Calcium chloride is most likely to be a redox reaction. However, experimentally if tested, I would say it would be most likely to proceed in forward direction as in water, potassium chloride has more solubility than calcium sulphate and KCl may precipitate out CaSO4 but CaSO4 doesn't precipitate out that easily.
