Crying gas or Tear gas, formally known as a lachrymator agent or lachrymator (from the Latin lacrima, meaning "tear"), sometimes colloquially known as mace,[NB 1] is a chemical weapon that causes severe eye, respiratory, and skin irritation, pain, bleeding, and even blindness. In the eye, it stimulates the nerves of the lacrimal gland to produce tears. Common lachrymators include pepper spray (OC gas), PAVA spray (nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromoacetone, xylyl bromide, syn-propanethial-S-oxide (from onions), and Mace (a branded mixture).

Lachrymatory agents are commonly used for riot control. Their use in warfare is prohibited by various international treaties. During World War I, increasingly toxic lachrymatory agents were used.

Nitrous oxide, commonly known as laughing gas, is a chemical compound with the formula N2O. It is an oxide of nitrogen. At room temperature, it is a colorless non-flammable gas, with a slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic and analgesic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anesthetic. It is also used as an oxidizer in rocketry and in motor racing to increase the power output of engines. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.

2 NH3 + 2 O2 ---> N2O + 3 H2O.

"laughing gas" - Due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anesthetic.

To add a point it is also used for treating ARDS (Acute Respiratory Distress Syndrome) in respiratory medicine.

Nitrous oxide, commonly known as laughing gas, is a chemical compound with the formula N2O. It is an oxide of nitrogen. At room temperature, it is a colorless, non-flammable gas, with a slightly sweet odor and taste

N2O FORMULA, USED COMMONLY for anesthetic operation. At room temperature it is clueless.

What is acetylene gas?

Nitrous oxide, commonly known as laughing gas, nitrous, nitro, or NOS is a chemical compound with the formula N2O. It is an oxide of nitrogen. At room temperature, it is a colourless, non-flammable gas, with a slightly sweet odour and taste.

Nitrous oxide, commonly known as laughing gas due to its property but it's injurious to health because a loss of consciousness.

Answer is carbon mono oxide because it causes dizziness, headache, colourless odourless and tasteless gas.
