Answer:
a. the mole fraction of CO in the mixture of CO and O2.
mole fraction = moles of CO/ Total moles of the mixture
Mole fraction of CO = 10/(10+12.5)=0.444
b. Reaction - CO(g)+½O2(g)→CO2(g)
Stoichiometry: 1 mole of CO react with 0.5mole of O2 to give 1 mole of CO2
So given,
At a certain point in the heating, 3.0 mol CO2 is present. Determine the mole fraction of CO in the new mixture.
3mol of CO2 is produced from 3 mols of CO and 1.5mol of O2
This means that unused mols are : 7mols of CO and 11mols of O2
Total product mixture = 3 + 7 + 11 = 21mols
mole fraction of CO = 7/21 = 0.33
Answer:
the answer is scientific question
Explanation:
Answer is: a product of a fermentation reaction is ethanol (C₂H₅OH).
Fermentation is a metabolic process in which ethanol is produced from sugar in the absence of oxygen (anaerobic digestion)<span>.
</span>Fermentation <span>occurs in </span>yeast, bacteria and in oxygen-starved muscle cells.
Fermentation is a way of extracting energy from molecules and it is <span>the oldest metabolic pathway.</span>
Answer:
C the number and placement of the electrons
Explanation:
Elements react with one another because they want to achieve a full valence shell of electrons. The noble gases already have a full valence shell of electrons, so they are unlikely to react with other elements.
