Calcium oxide and carbon dioxide react to form calcium carbonate, like this: CaO(s) + CO2(g) → CaCO3(s)

At a certain temperature, a chemist finds that a reaction vessel containing a mixture of calcium oxide, carbon dioxide, and calcium carbonate at equilibrium has the following composition:

Compound Amount
CaO 37.7 g
CO2 29.0 g
CaCO3 60.2 g

Calculate the value of the equilibrium constant Kc for this reaction.

C) electrons encircling a nucleus with neutrons and protons

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
