12) Assume COD entering an anaerobic digester can be modeled as C3H5O3 - , and it ferments via C3H5O2 - C2H3O2 - CO2 H2. Balance this reaction. Next, assume that methane in the reactor results from two pathways: aceticlastic methanogenesis and hydrogenotrophic methanogenesis. If we assume that all necessary carbon and hydrogen for methane production comes only from fermentation of lactate; how much methane (in mg/L) can be produced assuming 25,000mg/L COD entering the anaerobic digester, with all of it being fermented

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
