A few of them. Chlorine is one.
Sulfar gas
chermisty
it is an odorless colorless gas that readily assumes the odor of anything it passes through. It has no shape.
Ammonia is a colorless gas but has a strong odor! -LAH in LBG
A gas is produced when a chemical change takes place. The temperature changes and a substance disappears. A solid is formed and a color change has occurred. Another chemical change is that a new odor is produced.
Oxygen is a gas.- density: 1,429 g/L (but at 0 degrees)- atomic weight: 15,999- crystal structure: cubic- color: colorless- odor: no odor- melting point: -218,79C- boiling point: -182,962 COxygen is a gas at room temperature. It stays as diatomic molecules. This gas is colorless and odorless.
Natural gas has no color and it also has no odour. The odour that you can smell that is associated with gas, is man-made so that humans know that there is a gas leak. Otherwise, it would simply kill you :)
Neon is a gas without odor and color, with low density, low melting and boiling points, non toxic.

Neon is a gas without odor and color, with low density, low melting and boiling points, non toxic.
Most of the chemicals are odorless as water, air, salt ,Glucose e.t.c
Carbon Monoxide alarms are designed to detect Carbon Monoxide gas. The gas has no odor or color and is undetectable to humans until the effects have already taken hold.
