A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white crystalline substance B and a gas C. The gas ignites readily when combined with hydrogen gas and a liquid uncolored substance resulted. Based on these observations, can we determine whether solids A and B and gas C, are elements or compounds?

Respuesta :

Answer:

A and B as well C are the compounds.

Explanation:

  • A seems to be a compound, very least, it appears to contain carbon and oxygen.
  • C seems to be a compound, containing respectively oxygen as well as carbon.
  • B isn't always described by that of the information provided, it is therefore presumably a compound because there are few components as white solid particles.

So that the above is the correct answer.
