Answer:
Partial pressure of nitrogen gas is 0.98 bar.
Explanation:
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gases.
where,
= total pressure = 3.9 bar
= partial pressure of nitrogen gas
= partial pressure of oxygen gas
= partial pressure of argon gases
= Mole fraction of nitrogen gas = 0.25
= Mole fraction of oxygen gas = 0.65
= Mole fraction of argon gases = 0.10
Partial pressure of nitrogen gas :
Partial pressure of oxygen gas :
Partial pressure of argon gas :

Answer:
A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can be calculated if the dilution process is recorded. Beer's law only applies to dilute solutions, so diluting the unknown is better than making new standards.
Explanation:
Beer's law states that <em>absorbance is proportional to the concentrations of the absorbing species</em>. This is verified in the case of diluted solutions (0≤0.01 M) of most substances. <u>As a solution gets more concentrated, solute molecules interact between themselves because of their proximity. </u>When a molecule interacts with another, the change in their electric properties (including absorbance) is probable. That's why <u>the plot of absorbance versus concentration stops being a straight line</u>, and <u>Beer's law is no longer valid.</u>
Therefore, if the absorbance value is higher than the highest standard, dilutions should be made. Once this concentration is determined, the full strength concentration can be calculated with the inverse of the dilution.
Explanation:
Photosynthesis is the process whereby green plants uses light energy to manufacture food using carbon dioxide and water to produce energy rich glucose and oxygen gas as a bye - product.
The equation is given below:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
In the reaction above, the number of moles are:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
6 6 1 6
The reaction shows that 6 moles of carbon dioxide combines with 6 moles of water to give one mole of glucose and 6 moles of oxygen gas;
We can say that:
To produce 1 mole of glucose, we need 6 moles of carbon dioxide
1 mole of glucose, we need 6 moles of water
6 moles of oxygen gas we need 6 moles of carbon dioxide
6 moles of oxygen gas we need 6 moles of water molecules
