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.
What is solid B most likely to be?
a)compound
b)can not be determined
im thinking its a? is that correct?
and
What is gas C most likely to be?
a)compound
b)can not be determined
b?
solid B can not be determined because it doesn't have enough information and gas C is a compound
For the first question, we are told that when the 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. It is also mentioned that the gas C has the same properties as the product obtained when carbon is burned in an excess of oxygen.
To determine what solid B is most likely to be, we can consider the fact that the gas C has the same properties as the product obtained when carbon is burned in an excess of oxygen. When carbon burns in oxygen, it typically forms carbon dioxide, which is a compound consisting of carbon and oxygen.
Since the gas C has similar properties as the product obtained from burning carbon in oxygen, it is reasonable to assume that gas C is most likely carbon dioxide. Therefore, solid B is also likely to be a compound.
So, for the first question, the correct answer is (a) compound.
Now, moving on to the second question, we are asked what gas C is most likely to be. Based on the information given, we know that gas C has the same properties as the product obtained from burning carbon in oxygen.
As mentioned earlier, when carbon is burned in an excess of oxygen, it produces carbon dioxide. Carbon dioxide (CO2) is a compound consisting of carbon and oxygen.
Therefore, based on this information, it is reasonable to assume that gas C is most likely to be a compound, specifically carbon dioxide (CO2).
So, for the second question, the correct answer is (a) compound.
Hence, the correct answers to the questions are (a) compound for both solid B and gas C.
