Question

What three compounds are best for melting marble?

Answer 1

marble is a form of calcium carbonate and contains imprities thatgive it its aesthetcally pleasing appearance. In nature marble isformed by the melting of sedimentary calcium carbonate under highpressure and high temperature conditions. Melting calcium carbonateis very difficult under normal conditions, as it decomposes to fromCO 2 and CaO. As the decomposition reaction is reversibleit is possible that a sample of finely divided marble heated underhigh pressure CO2 to will prevent decomposition will melt
