Answer:
H₂ is excess reactant and O₂ the limiting reactant
Explanation:
Based on the chemical reaction:
2H₂(g) + O₂(g) → 2H₂O
<em>2 moles of H₂ react per mole of O₂</em>
<em />
To find limiting reactant we need to convert the mass of each reactant to moles:
<em>Moles H₂ -Molar mass: 2.016g/mol-:</em>
10g H₂ * (1mol / 2.016g) = 4.96 moles
<em>Moles O₂ -Molar mass: 32g/mol-:</em>
22g O₂ * (1mol / 32g) = 0.69 moles
For a complete reaction of 0.69 moles of O₂ are needed:
0.69mol O₂ * (2mol H₂ / 1mol O₂) = 1.38 moles of H₂
As there are 4.96 moles,
<h3>H₂ is excess reactant and O₂ the limiting reactant</h3>
Explanation:
Usually most cells that carry anaerobic respiration utilize the Glycolysis pathway because it does not require oxygen. It is also believed it is the ancient metabolic pathway by utilized by primordial cells when the earth's atmosphere was not mainly oxygen,
Glycolysis consumes 2 ATPs (during the conversion of Glucose to Fructose 1,6 bisphosphate ) but produces a gross $ ATPs. It, therefore, has a net ATP of 2. This is inefficient when compared to the Krebs cycle that utilizes oxygen to produce 34 ATPs. Anaerobic respiration produces pyruvate. This pyruvate is broken down into an organic acid like lactic acid which is excreted from the cell, which is why fermented food tastes sour.

Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.
