Dry ice has the same chemical properties as which of the following gases?
A
carbon dioxide (CO_2)
B
methane (CH_4)
C
oxygen (O_2)
D
nitrogen (N_2)
Verified step by step guidance1
Understand that dry ice is the solid form of a gas that has been cooled and compressed to become solid without passing through a liquid phase (sublimation).
Recall the chemical composition of dry ice, which is solid carbon dioxide, represented by the formula \(\mathrm{CO_2}\).
Compare the chemical formulas of the given gases: carbon dioxide (\(\mathrm{CO_2}\)), methane (\(\mathrm{CH_4}\)), oxygen (\(\mathrm{O_2}\)), and nitrogen (\(\mathrm{N_2}\)).
Recognize that since dry ice is solid carbon dioxide, it shares the same chemical properties as gaseous carbon dioxide (\(\mathrm{CO_2}\)).
Conclude that the gas with the same chemical properties as dry ice is carbon dioxide (\(\mathrm{CO_2}\)).
