webmaster Posted December 26, 2004 Share Posted December 26, 2004 From: Paul Foellbach Subject: swapping in Rxn I have got a question about RXN. I am interested in the reaction of Calcite. If I give the command "react Calcite" the following reaction is given as result: Calcite = CO3-- + Ca++. If I try to swap the QUARTZ for any species that contains O or Si like CO3-- the RXN answers Rxn > swap Quartz for HCO3- -- Mineral Quartz can only be swapped in for: SiO2(aq) Can you tell me how I figure the reaction of the SILICATION: CaCO3 + SiO2 = CaSiO3 + CO2(g) ?
