Problem: A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white substance B and a gas C. The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen.Based on these observations, can we determine whether gas C is an element or a compound?
