i hope you had understand !
Hey there!
The correct answer to your question is option A.
The result of adding more solute to a solution is the boiling point increases.
Another name of the boiling point increasing is "Boiling point elevation".
The reason why solute increases the boiling point is because when the solute is added to the water, the energy increases.
Hope this helps you.
Have a great day!
The nucleus and the electron cloud are the two parts !!
if you need explanation ; comment !!
CH₃COOH millimoles = 52 x 0.35 = 18.2
NaOH millimoles = 27 x 0.4 = 10.8
CH₃COOH + NaOH → CH₃COONa + H₂O
18.2 10.8 0 0 -----> Initial
- 10.8 - 10.8 + 10.8 + 10.8 -----> Changed
7.4 0 10.8 10.8 ------> after reaction
Now the mixture contain acid and salt so it forms buffer
pKa = - log Ka = - log (1.8 x 10⁻⁵) = 4.74
pH = pKa + log [salt] / [acid]
pH = 4.74 + log [10.8] / [7.4]
pH = 4.9
Mike would be right, since there are only 3 electrons in the shell, if shows that there are 3 protons. Lithium is the only element with 3 protons
