Part A Which of the following represents a chemical property of hydrogen gas? Which of the following represents a chemical property of hydrogen gas? It is gaseous at room temperature. It is colorless. It is tasteless. It reacts explosively with oxygen. It is less dense than air.

It reacts explosively with oxygen.

Explanation:

Reactivity is a chemical property.

Taste, temperature, and density are all chemical properties.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
