A 0.245-L flask contains 0.467 mol co2 at 159 °c. Caculate the pressure using Van der Walls equation

AlladinOne [14]

Answer:

The right answer is "60.56 atm".

Explanation:

As we know,

Vander wall's equation is:

⇒ $(P+\frac{n^2 a}{v^2} )(v-nb)=nRT$

or,

⇒ $P=\frac{nRT}{(v-nb)}-\frac{n^2 a}{v^2}$

Here,

a = 3.59 L² atm mol⁻²

b = 0.0427 L mol⁻¹

By putting the values in the above equation, we get

⇒ $P=\frac{0.467\times 0.0821\times 432}{0.245-0.467\times 0.0427}$

$=\frac{(0.467)^2\times 3.49}{(0.245)^2}$

$=73.61-13.05$

$=60.56 \ atm$

Compare and contrast an electrolytic cell with a voltaic cell. Provide one example where both are present in daily life.

joja [24]

$\huge \underline \fcolorbox{red}{pink}{answer}$

Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction. Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells. ... This is because the sites of oxidation (the anode) and reduction (the cathode) are switched.

Physical Properties

1. Metals are shiny but most non - metals lack this property.

2. Metals are able to deform under compression (malleable) but most non - metals lack this property.

Chemical Properties

1. Metals are good conductorsof heat and electricity but most non - metals are insulators.
