Good morning everyone!
This is a very interesting video on chemical reactions.The most important thing you need to remember about chemical reactions is that MATTER changes… so there is no coming back to original substance.
One chemical reaction is fermentation… that is carried out by a living organism… and remember they always have three vital functions.. NUTRITION leaves WASTE… have a look at this video… and see what happens when our small yeast eats sugar and releases waste in gas state…..
IF YOU HAVE A DOUBT WRITE IT AS A COMMENT. IF YOU DON’T STILL SAY HELLO (WITH YOUR FIRST LETTERS OF NAME, SURNAMES AND GROUP, just so I can know you are connected and learning)
