Question

_________ gas causes tears in our while cutting onion​

Answer 1

Answer:

When an onion is sliced or diced, the onion's cells release these compounds into the air. When this occurs, "enzyme" works to alter the amino acids into lachrymator compounds. This form of sulfuric acid irritates the nerves around the eyes making them tear.

Answer 2

Answer:

Onions use sulfur in the soil to create amino acid sulfoxides, which are sulfur compounds that readily turn into a gas. When an onion is cut open, it releases the sulfoxides and enzymes, which react and create a gas called syn-propanethial-S-oxide.
