Answer:
Using the information provided in the question, the percentage by mass of ethanol in the blood is 0.1949%.
Explanation:
The balanced equation for the reaction can be written as:
3CH3CH2OH + 2K2Cr2O7+ 16H+ >>>> 3CH3COOH + 4Cr3+ + 4K+ + 11H2O. This will be used to solve the problem.
The no of moles of K2Cr2O7 used = concentration X volume in dm cube.
= 0.05 X 22.6/1000 = 1.13/1000 = 0.00113 moles of K2Cr2O7 was used.
From the balanced equation above, 3 moles of ethanol will react with 2 moles of K2Cr2O7.
Therefore, 0.00113 X 3/2 moles of ethanol would have been in the blood of the subject = 0.001695 moles of ethanol.
Remember that no of moles = mass/molar mass. Then mass = moles X molar mass.
The molar mass of ethanol is 46g/mole.
Then mass = 0.001695 X 46 = 0.07797gram of Ethanol was in the blood.
Percentage by mass in blood is: 0.07797/40 X 100 = 0.1949%
I think the reaction involved here is a redox reaction in acidic conditions. To balance this type of reaction, we do as follows:
Balance the O atoms in each side by adding H2O on either side.
Balance H atoms in each side by adding H+.
Balance the charges by adding electrons.
Hope this helps.
Answer:
Explanation:
Hello,
In this case, we can study the ideal gas equation that relates temperature, volume, pressure and moles as shown below:
Thus, since we are asked to compute the pressure y simply solve for it as follows:
Best regards.
Chemical process is responsible for the smell of vinegar in an old bottle of aspirin is Hydrolysis of ester i.e. Aspirin.
Aspirin reacts with water leading to the formation of Acetic acid which is a Carboxylic acid derivative.
Aspirin on Hydrolysis forms Acetic acid and Salicylic acid.
The reaction shows up as a fizz when aspirin is added in water.
Aspirin is called Acetyl Salicylic acid and it helps to reduce:
- Inflammation
- Pain
- Fever
- Headache
- Arthritis
- Muscle pain
- Tooth pain
Acetic acid or Ethanoic acid is a colorless liquid. It is an important carboxylic acid. It smells like vinegar.
Acetic acid is used for production of following:
- Vinyl Acetate
- Insecticides
- Rubber
- Acetic anhydride
Salicylic acid is a bitter compound which is colorless. It reduces acne and opens up the skin pores.
