phosphorus to consumed PHA under anoxic condition was 063, which was 24% lower than 0.83 under aerobic condition; the amount of phosphorus taken up to per mole of electrons transferred under anoxic condition was 014 mol, which was 391% lower than 023 mol with oxygen as the electron acceptor....
In order for this equation to be balanced the coefficient of two had to be placed before the oxygen (O2) and the water (H2O). No number was placed before the methane (CH4) and the carbon dioxide (CO2) because the equation is balanced with just one of each of them. Balanced equation ...
You may have never seen the fuzzy, pointy-nosed animal called a mole even if you know what a mole is, since it lives underground most of the time.One mole is the mammal with beady little eyes that burrows underground eating earthworms. This mole doesn't need much oxygen to breathe and ...
Without oxygen, the usual decomposition doesn’t happen, and the only bacteria that can break down the moles are those which don’t require oxygen. While inefficient, this anaerobic decomposition can unlock quite a bit of heat. If continued unchecked, it would heat the planet to a boil. But...
(c)22g of carbon dioxide. Q.A certain mass of carbon required16gramsof oxygen to be converted into carbon monoxide. To convertCOinto carbon dioxide(CO2), the mass of oxygen required would be: Q.Convert 12g of Oxygen gas into moles. ...
one mole of carbon-12 atoms has 6.02214076 × 1023atoms and a mass of 12 grams. In comparison, one mole ofoxygenconsists, by definition, of the same number of atoms as carbon-12, but it has a mass of 15.999 grams. Oxygen, therefore, has a greater mass than carbon. This reasoning als...
provides a vital link that allows scientists to connect the number ofparticlesin a substance to both the combinedmassof all those particles and the mass of each individual particle. As we’ve seen, the mole concept is useful for so much more than just referring to the amount of a substance...
The molar mass of Hydrogen is 1.0079 g/mol The molar mass of Oxygen is 15.9994 g/mol It is common when expressing molar masses to round off to the first two decimal places, making the molar mass of water 18.02 g/mol. When determining molar masses, the mass of the electrons around an...
