Meso−2,3−butanediol is the product of the top reaction
Carbon Dioxide, water vapor, Argon, and I think neon.
when water pipes burst due to the pressure of expanding water when it freezes thats how it forms hope this help can i have a brainliest please
Lactic and alcholic happens when there is no oxygen.
So, how did it happen?
Recall that in glycolysis of cellular respiration, there is a glucose (6 Carbons) molecule. That glucose molecule is going to be broken down into two pyruvates (3 Carbons). There is no oxygen (also know as anaerobic respiration) so pyruvate is going to be converted into lactate or alcoholic fermentation depending on it's accessibility. I highly suggest you to watch this video if you don't get what I'm talking about:
