Problem- Which of the following are physical rather than chemical properties of hydrogen gas(H2)? Check all that apply
- H2 gas does not conduct electricity.
- Liquefied H2 boils at a very low temperature (-253.7oC)
- It reacts vigorously with oxygen (O2) to form water.
- At room temperature, its density is less than that of any other gas
