[@Sam-bf7lw]

Ethylene is also called acetylene.

Ripining of fruits By Ethelyene...by u r showing smthng..Bro

[@sachindagar710]

Acetylene acid is the 2nd name of ethylene acid. By the way both are correct.

[@Chemistrysparkle]

Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is similar in its effects to the natural ripening agent, ethylene. Acetylene accelerates the ripening process.

[@pieterhuman8049]

Nice quiz. I'm a chemical engineer. Two issues. Ethylene or Ethene is the gas that helps in the ripening of fruit. It's a member of the Alkene homologous series. Acetylene or Ethyne is an Alkyne. Very different. Ice cubes melting is both an endothermic and reversable process.

[@AgnibeshNath-su1bs]

Yes . But are the questions wrong?

[@rajarajacholan1-ym6mv]

It can't be reversible it is not spontaneous

[@jdelacruz14791]

@@rajarajacholan1-ym6mv Ice cubes can melt by increasing heat, or by decreasing the pressure. And they can freeze by decreasing heat or increasing pressure. You can pretty much keep doing this for as long as you want. Which makes it a reversible process
