@X@user.full_name@X@ @GMU: Which of the answers below is the correct representation according to the shorthand method of the following cell?3Ag+(aq) + undefined → 3Ag(s) + Cr3+(aq)

@X@user.full_name@X@ @GMU: Kaolinite, a clay mineral with the formula Al4Si4O10(OH)8, is produced naturally by the chemical weathering of aluminum silicate minerals like feldspar (granite). Kaolinite is used industrially as filler in slick-paper for magazines and as a raw material for ceramics. How many grams of oxygen are present in 11.96 g of kaolinite?
