Calculate the volume in ml of 0.20m naoh needed to react completely with 100.ml of 0.040m acetic acid.
1 answer:
Hello!
You'll need 20 mL of 0,20 M NaOH to react completely with 100 mL of 0,040 M Acetic Acid.
The reaction between NaOH and Acetic Acid is the following:
NaOH + CH₃COOH → H₂O + CH₃COONa
To calculate the volume of 0,20 M NaOH needed to react completely with 100 mL of 0,040 M Acetic Acid, we'll need to use the following equation (Molar equivalence) and clear for Volume of NaOH:
Have a nice day!

Answer:
e. None of these.
Explanation:
Hey there!
In this case, since the Henry's law is defined in terms of pressure, henry's constant and pressure, as shown below:
Whereas C is the concentration, KH the Henry's constant and P the pressure, we infer that the concentration of a gas solution is directly proportional to the pressure, which is not the group choices, therefore, the answer is e. None of these.

Density of liquid= .
so, density of liquid= = 1.2 gm/cm³.
The energy absorbed by the system before the reaction start has been 752 kJ/mol.
The bond energy has been defined as the energy possessed by the bond that has been converted into the heat energy and utilized in the reaction.
The energy has been conserved in a chemical reaction. Thus, the energy absorbed by the reactant in the reaction has been the difference in the energy of the reactant and product.
<h3>Computation for the energy absorbed</h3><h3 />The given reaction has been:
The bond energy of the reactant has been:
H-H bond energy = 432 kJ/mol
2 C=O bond energy= 799 kJ/mol
The total energy of the reactant has been 432 kJ/mol + 799 kJ/mol
The total energy of the reactant has been 1231 kJ/mol
The bond energy of the product has been:
C-O bonds = 358 kJ/mol
C=O bonds = 745 kJ/mol
1 C-H bond = 413 kJ/mol
1 O-H bond = 467 kJ/mol
The total energy of the product has been 358 + 745 + 413 + 467 kJ/mol
The total energy of the product has been 1,983 kJ/mol
According to the law of conservation of energy:
Substituting the values for energy absorbed:
The energy absorbed by the system before the reaction start has been 752 kJ/mol.
