Solution
The correct option is C M: Calcium carbonate
G: Carbon dioxide
The gas released does not support combustion, so the gas can be carbon dioxide.
As one of the products is calcium chloride, hence metal carbonate is calcium carbonate.
G: Carbon dioxide
The gas released does not support combustion, so the gas can be carbon dioxide.
