Answer;
Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.
Explanation;
-Anaerobic respiration is a type of respiration that does not use oxygen. It is used when there is not enough oxygen for aerobic respiration.There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
-The carbon dioxide produced as a by-product when yeast perform alcoholic fermentation on the sugar in the bread mix is the gas that causes dough to rise. The sugars in produce like barley, grapes and other grains and fruits is what allows yeast to produce the bubbles and alcohol in beer, wine and other liquors.
Answer:
The theoretical yield of carbon dioxide formed from the reaction of methane and oxygen gas is 1 mol.
Explanation:
The equation below shows the reaction of combustion of methane:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
When no reactants are wasted and the reaction is complete, 1 mol of gaseous CO₂ will be produced. This means that the theoretical yield of carbon dioxide is 1 mol.
So the molarity equation is moles of solute/liters of solution. so i’m pretty sure the answer should be 0.63/0.70= .9
Answer:
Q = 1.08x10⁻¹⁰
Yes, precipitate is formed.
Explanation:
The reaction of CoF₂ with NaOH is:
CoF₂(aq) + 2 NaOH(aq) ⇄ Co(OH)₂(s) + 2 NaF(aq).
The solubility product of the precipitate produced, Co(OH)₂, is:
Co(OH)₂(s) ⇄ Co²⁺(aq) + 2OH⁻(aq)
And Ksp is:
Ksp = 3x10⁻¹⁶= [Co²⁺][OH⁻]²
Molar concentration of both ions is:
[Co²⁺] = 0.018Lₓ (8.43x10⁻⁴mol / L) / (0.018 + 0.022)L = <em>3.79x10⁻⁴M</em>
[OH⁻] = 0.022Lₓ (9.72x10⁻⁴mol / L) / (0.018 + 0.022)L = <em>5.35x10⁻⁴M</em>
Reaction quotient under these concentrations is:
Q = [3.79x10⁻⁴M] [5.35x10⁻⁴M]²
<em>Q = 1.08x10⁻¹⁰</em>
As Q > Ksp, <em>the equilibrium will shift to the left producing Co(OH)₂(s) </em>the precipitate
