Carbon dioxide
Hydrogen gas
Yeasts give off gas as they consume and digest sugars. The bubbles of gas become trapped in the dough, causing the product to rise.
you can not measure gas of yeast
It gives off carbon dioxide which proves that it respires.
By fermentation, yeast converts carbohydrates to carbon dioxide and alcohol. Yeast has been used in baking for centuries as well as alcohol making.
It depends what acid or metal it is but usually they either give of a gas, increase temperature or give off effervescence.
Acid gives off hydrogen gas if it is hydrogen containing acid.
Yeast will respire the sugar causing the yeast to give off Carbon Dioxide.
Hydrogen
Yeast froths when put in peroxide because the acidic nature of peroxide reacts chemically with the products of yeast, causing hydrogen to be given off and froth to fizz rapidly.
