At 650 mm hg a gas has a volume of 190 l what is its volume at standard pressure

Chemistry
1 answer:
vovangra [49]3 years ago

Answer:Volume occupied by the gas at standard pressure is 162.5 L.

Explanation:

Pressure of the gas when it occupies volume of 190 L = 650 mmHg

Volume occupied by the gas when the gas is at standard pressure.

The value of standard pressure = 1 atm = 760 mmHg

P_1=650 mmHg,V_1=190 L,P_2=760 mmHg,V_2=?

According to Boyle's Law: Pressure\propto \frac{1}{Volume} (at constant temperature)

P_1\times V_1=P_2\times V_2

V_2=\frac{P_1\times V_1}{P_2}=\frac{650 mmHg\times 190 L}{760 mmHg}=162.5 L

Volume occupied by the gas at standard pressure is 162.5 L.

An interpenetrating primitive cubic structure like that of CsCl with anions in the corners has an edge length of 664 pm. If the
san4es73 [151]

Answer:

the ionic radius of the anion r^- = 312.52 \ pm

Explanation:

From the diagram shown below :

The anion Cl^- is located at the corners

The cation Cs^+ is located at the body center

The Body diagonal length =  \sqrt{3 \ a }

∴ 2 \ r^+ \ + 2r^- \ = \sqrt{3 \ a}  \\ \\ r^+ +r^- = \frac{\sqrt{3}}{2} a

Given that :

\frac{r^+}{r^-} =0.84   (i.e the  ratio of the ionic radius of the cation to the ionic radius of

                 the anion )

0.84r^- \ + r^- \ = \frac{\sqrt{3}}{2}a  \\ \\  1.84 r^- = \frac{3}{2}a \\ \\ r^- = \frac{\sqrt{3}}{2*1.84}a

Also ; a =  664 pm

Then :

r^- = \frac{\sqrt{3} }{2*1.84}*664 \ pm\\ \\ r^- = 312.52 \ pm

Therefore,  the ionic radius of the anion r^- = 312.52 \ pm

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. when placed in water, the block sinks
Art [367]

 When the block  of iron is  placed  in water  the volume of water that   is  displaced is  27.0  cm³


  <u><em> calculation</em></u>

The  volume water that is displaced is equal to volume of block  of the iron


volume of block of iron = length x width x height

   length= 3 cm

   width = 3  cm

 height = 3 cm

volume  is therefore = 3 cm  x  3 cm x  3  cm = 27  cm³   therefore the volume displaced  = 27 cm³  since the volume of water displaced  is equal to  volume of block.

Please Help! I just started balancing equations and my teacher gave me this. Thanks in advance! :D
Alenkasestr [34]
So you need to put numbers before each compound to make sure there are the exact same number of elements on each side. If you put a 4 before NH4 there are 4 Nitrogen and now 16 hydrogen. I just played around with numbers and guessed until I got them even.
