Question

When 10.0 grams of A was heated, 4.40 grams of B was given off, leaving 5.60 grams of E.   The same quantity of B can also be prepared by combination of 1.2 grams of C and 3.2 grams of D.  C decomposes to form a new substance while D was found to contain two chemical     elements. The E can be electrolyzed  after melting  to yield 4.0 grams of F and 1.6 grams of G,   neither  of which can be further decomposed by ordinary chemical means.  E combines  with water to give 1.3 grams of J per gram of E and gas L. The gas L has exactly the same    properties as the product obtained when carbon is burned in an excess of oxygen.
