Question

A student attempted to identify an unknown compound by the method used in the experiment. She found that when she heated the sample weighing 0.4862g, the mass barely changed, dropping to 0.4855g. When the product was converted to a chloride, the mass went up to 0.5247g. Is the sample a carbonate? What are the two compounds that might be the unknown?
