Question

Name:
1. Greenish yellow gas
2. Brown gas
3. Burns with pop sound

Answer 1

1) Chlorine

2) Oxyhydrogen

3) Hydrogen

Explanation:

I) Greenish yellow gas is Chlorine.

Chlorine is a toxic, corrosive, greenish-yellow gas that is irritating to the eyes and to the respiratory system. This gas combines directly with nearly all elements.

2) Brown gas is oxyhydrogen.

Oxyhydrogen is a mixture of hydrogen (H2) and oxygen (O2) gases. This gaseous mixture is used for torches to process refractory materials and was the first gaseous mixture used for welding. Brown's gas and HHO are terms for oxyhydrogen.

3) Hydrogen burns with pop sound.

The pop sound comes from the small explosion formed by the burning of Hydrogen with oxygen. Other common gasses, such as water vapour, nitrogen, and carbon dioxide will not burn with oxygen.
