<u>Answer:</u> The boiling point of solution is 100.62°C
<u>Explanation:</u>
Elevation in boiling point is defined as the difference in the boiling point of solution and freezing point of pure solution.
The equation used to calculate elevation in boiling point follows:
To calculate the elevation in boiling point, we use the equation:
Or,
where,
Boiling point of pure water = 100°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal boiling point elevation constant = 0.512°C/m.g
= Given mass of solute = 23.6 g
= Molar mass of solute = 103.5 g/mol
= Mass of solvent (water) = 188 g
Putting values in above equation, we get:
Hence, the boiling point of solution is 100.62°C
Answer:
C5H5N is the base and C5H5NH+ is the conjugate acid
H2O is the acid and OH− is the conjugate base
Explanation:
<u>Hydrogen + is also called a proton</u>
C5H5N is the base because it receives the proton (H+) and C5H5NH+ is its conjugate acid
H2O is the acid because it gives up the proton and OH− is the conjugate base because it is capable of receiving the proton
Answer:
HNO3 is the acid and NO3- is the conjugate base
H2O is the base and H3O+ is the conjugate acid
Explanation
HNO3 is the acid and NO3− is its conjugate base, capable of receiving a proton
H2O is the base because it receives the proton and H3O+ is a conjugate acid capable of giving up the proton.
Answer:
hydroxide ion would be the answer
Answer:
Explanation:
The ionization constant of the water = at a temperature of and pressure of 20 MPa
Water dissociates as;
The expression for the ionization constant is :
For pure water,
So,
The concentration of the hydroxide ions, .
Answer:
It is called the superior sagittal sinus.
Explanation:
The superior sagittal sinus which is often called the superior longitudinal sinus) is situated in the human head. It is an unpaired region in the human head around the attached margin of the falx cerebri. It main function is to ensure that blood is removed from the lateral parts of the anterior cerebral hemispheres and transferred to the confluence of sinuses. It also has a triangular cross sectional area and with a left/right lateral angles at its junctions. Therefore, The right answer is the the superior sagittal sinus.
