Answer: Option (d) is the correct answer.

Explanation:

Density is defined as mass per unit volume.

Mathematically, $d = \frac{m}{v}$

where d = density

m = mass

v = volume

Density is also known as degree of compactness, that is, more closely the atoms are linked more will be the mass of object or atom. Hence, more will be its density.

Thus, we can conclude that $density = \frac{mass}{volume}$

Read the given expression. X = number of protons − number of core electrons Which of the following explains the identity of X an

shepuryov [24]

Answer: The correct statement is X is the effective nuclear charge, and it increases across a period.

Explanation:

We are given that:

X = number of protons − number of core electrons

Effective nuclear charge is defined as the actual nuclear charge (Z = number of protons) minus the screening effect caused by the electrons present between nucleus and valence electrons. These electrons are the core electrons.

The formula used for the calculation of effective nuclear charge given by Slater is:

$Z^*=Z-\sigma$

where,

$Z^*$ = effective nuclear charge

Z = atomic number or actual nuclear charge or number of protons

$\sigma$ = Screening constant

The effective nuclear charge increases as we go from left to right in a period because nuclear charge increases with no effective increase in screening constant.

Hence, the correct answer is X is the effective nuclear charge, and it increases across a period.

The p K a of hypochlorous acid is 7.530 . A 60.0 mL solution of 0.103 M sodium hypochlorite ( NaOCl ) is titrated with 0.296 M H

IrinaVladis [17]

Answer:

pH of the solution after addition of 8 ml 0,296 molar HCl = 7.94

Explanation:

In this case buffer exist between hypochlorous acid HClO is a weak acid and its conjugate base hypochlorite ion ClO⁻ which are deliver to the solution by NaOCl ( sodium hypochlorite ).

The salt is completely dissociate

[NaOCl] = [ClO⁻]

Using Henderson equation to find pH of this buffer

pH = pKa + log $\frac{[Conjugate base]}{[Acid]}$

or, = 7.53 + log $\frac{60 X 0.103}{8 X 0.296}$

or, = 7.53 + 0.4

or, = 7.94
