Answer: Hydrogen is a colorless, tasteless, and odorless gas : Physical property
Hydrogen is very combustible in the presence of oxygen: Chemical property
Hydrogen is very reactive with most elements : Chemical property
Hydrogen is the least dense of all elements: Physical property
Explanation:
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
