D. All of these

Explanation:

Hi,

So, let's go,

The first thing to know, is that strong acids has a lot of H+ free in solution. While weak acids doesn't have a lot of H+ free.

Now, analyzing the letters

A. Electrical current conduction has a lot of free electrons, so, strong acids has a lot of H+ free in solution too. The combination of these two, in large amount, results in a strong reaction. Very differently with weak acids, which has a few free electrons.

B. ph paper test works with a scale of colors. This means that at one end the acid is strong, and at the other the acid is weak. So, if you drip a drop of the strong acid, the ph paper test will show you different color that when you drop a weak acid.

c. Magnesium is an element from IIA family, that means he reacts strongly with electrons and íons. Which is the cafe os strong acids.

I hope that all questions is solved.

Bye! See ya

answer : (a) volume of the gas = 8.67 × $10^{-3}$ l

(b) second virial coefficient b = -1.21226 l/mole

solution : given, t = 300k

p = 20atm

z = 0.86

n = 8.2 mmoles = 8.2 × $10^{-3}$ moles

r = 0.082 l atm/k/mol

find, (a) volume of gas and (b) second virial coefficient b at 300k.

formula used : $z=\frac{pv}{nrt}$

and $z=1+\frac{b}{v}$

(a) $z=\frac{pv}{nrt}$

$v=\frac{znrt}{p}$

= $\frac{0.86\times 8.2\times[tex]10^{-3}$ \times 0.082\times 300}{20}[/tex]

= 8.67 × $10^{-3}$ l

(b) $z=1+\frac{b}{v}$

$b=(z-1)v$

= (0.00867-1) × 8.659

= - 8.5839 l/mole
