A sample of chlorine gas occupies a volume of 707 ml at 2.90 atm. What is the new pressure in torr if the volume is compressed t

dolphi86 [110]

Answer:

The new pressure is 3850 torr.

Explanation:

The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

$P_1V_1=P_2V_2$

Here,

$P_1=2.9\ atm$

$V_1=707\ mL$

$V_2=0.533\ L$

Let $P_2$ is the new pressure. So using Boyle's law we get :

$P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{2.9\times 707}{0.533}\\\\P_2=3846.71\ \text{torr}$

$P_2=3850\ \text{torr}$

So, the new pressure is 3850 torr.

Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium cathode

miskamm [114]

Answer:

544.522 Hours

Explanation:

a) Mass = 12.5 kg = 12500 g

Now, Number of moles is given as

No of moles = Mass of Cr / Molar mass of Cr

$=\frac{12500}{52}$

= 240.38 moles

$Cr^{3+}\Rightarrow$ 3 mols of electrons are required

$\Rightarrow 240.38\times3 =721.14\text{mol of e-}$

Converting moles of e- to coulombs of charge, (1 mol of electrons = 96500 C )

Q =721.14 mol×96500 C/mol

=69590010 of charge

We know that, Q = I×t

where Q is charge, I is current and t is time required.

$\Rightarrow t =\frac{Q}{I}$

$=\frac{69590010}{35.5}$

=196281.97 seconds

$=\frac{1.96281\times10^5}{3600}$

=544.522 Hours
