den301095 [7]

Answer:

Geosphere and Hydrosphere.

Explanation:

Hot springs are heated by geothermal heat—heat from the Earth's interior. In volcanic areas, water may come into contact with very hot rock heated by magma. The geosphere and hydrosphere interact when hot springs form. The geosphere gets a little melted by the hot hydrosphere and then when the springs shoot up in the air they break some rocks.

What mass of neon gas is required to fill a 5.00-L container to<br> a pressure of 1.02 atm at 25 °C?

sweet [91]

Answer:

$m=4.21g$

Explanation:

Hello,

In this case, by using the ideal gas equation:

$PV=nRT$

We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):

$n=\frac{PV}{RT}=\frac{1.02atm*5.00L}{0.082\frac{atm*L}{mol*K}*298K}\\ \\n=0.209mol$

Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:

$m=0.209mol*\frac{20.18g}{1mol}\\ \\m=4.21g$

Best regards.

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in

Gnoma [55]

Answer:

$E=4.5\times 10^{-18}\ J$

Explanation:

It is given that, the frequency of Ultraviolet radiation is $6.8\times 10^{15}\ Hz$

We need to find the energy of the photon. The formula for the energy of a photon is given by :

$E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J$

So, the energy of the photon is $4.5\times 10^{-18}\ J$ .

What are the functions of ammonia in the solvay process

enot [183]

The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.
