Answer:
1M
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below:
NaOH + HCl —> NaCl + H2O
From the equation above,
nA (mole of acid) = 1
nB (mole of the base) = 1
Data obtained from the question include:
Vb (volume of base) = 50mL
Mb (Molarity of base) = 0.2M
Va (volume of acid) = 10mL
Ma (Molarity of acid) =?
Using MaVa/MbVb = nA/nB, we can calculate the molarity of the acid as follow:
Ma x 10/0.2 x 50 = 1
Cross multiply to express in linear form
Ma x 10 = 0.2 x 50
Divide both side by 10
Ma = (0.2 x 50)/10
Ma = 1M
The molarity of the acid is 1M
a) attraction between ions causes the dispersion forces.
Attraction between ions is a temporary attractive force which occurs when electrons in two consecutive adjacently placed atoms occupies positional confined areas that make the atoms acting like Temporary dipoles.
Dispersion forces or London Dispersion forces is the weakest force caused due to motion of electron.
On increasing the number of electrons the magnitude to Dispersion forces increases.
Dispersion forces also depends upon the atomic or the molecular weight of the given substance.
It is caused by an unequal and uneven distribution of the electrons inside an atom.
This causes a slight positive and slight negative charge to be formed inside an atom by establishing a temporary dipole. This temporary dipole induces a nearby atom by inducing another temporary dipole in the other one.
