Verified step by step guidance1
Understand the difference between physical and chemical properties. Physical properties can be observed without changing the substance's chemical identity, while chemical properties describe a substance's ability to undergo a chemical change.
Identify the options given: existence as a gas at room temperature, being less dense than air, reacting explosively with oxygen gas, being colorless, and being tasteless.
Determine which of these options involves a chemical change. A chemical change involves a reaction where the substance's chemical structure is altered.
Recognize that 'reacts explosively with oxygen gas' describes a chemical reaction, indicating a change in the chemical structure of hydrogen gas when it combines with oxygen to form water.
Conclude that the property 'reacts explosively with oxygen gas' is a chemical property, as it involves a chemical reaction, unlike the other options which describe physical properties.
