Radiation has optimized a number of process in the plastics industry.  Infrared emitters are the devices that uses radiation which are used in the said industry. These are devices which could be adjusted precisely depending on the product and the process. These emitters can make plastics welding within seconds.  And since they can be adjusted precisely, it saves a lot of time, space and of course energy.

Answer:

Sublimation

Explanation:

Sublimation is when a substance goes from a solid to a gas, without going through a liquid phase. This is not a method for separation and purification.

What direction would equilibrium moves towards based on the following if we increased the volume of the container.
Liono4ka [1.6K]

To answer this question, we will first find out the number of gaseous moles on each side of the equilibrium

<u>on the left:</u>

we have 2 moles of A, 5 moles of B and 12 moles of C

which gives us a grand total of <u>19 gaseous moles</u>

<u>on the right:</u>

here, we have 14 moles of AC gas, we will not count the number of moles of B because it's a solid

giving us <u>14 gaseous moles</u> on the right

<u>Where does the reaction shift?</u>

more gaseous moles means more space taken, because gas likes to fill all the space it can

if we have more volume, more gas can move around without colliding (reacting) with each other

Hence more volume favors the side with more gaseous moles

here, the left has more gaseous moles. So we can say that the reaction will shift towards the left, or the reactants side

A gas mixture consists of 60.0% Ar, 30.0% Ne, and 10.0% Kr by volume. If the pressure of this gas mixture is 80.0 kPa, what is t
Nat2105 [25]

Answer: The partial pressure of Argon , Neon and krypton are 48 kPa , 24 kPa and 8 kPa respectively.

Explanation:

According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

p_A=x_A\times P_{total}

where, p_A = partial pressure of component A

x_A = mole fraction of A

P_{total} = total pressure

mole fraction of Ar = \frac{\text {Moles of Ar}}{\text {total moles}}=\frac{60.0}{60.0+30.0+10.0}=0.6

p_{Ar}=0.60\times 80.0kPa=48kPa

mole fraction of Ne = \frac{\text {Moles of Ne}}{\text {total moles}}=\frac{30.0}{60.0+30.0+10.0}=0.30

p_{Ne}=0.30\times 80.0kPa=24kPa

mole fraction of Kr = \frac{\text {Moles of Kr}}{\text {total moles}}=\frac{10.0}{60.0+30.0+10.0}=0.10

p_{Kr}=0.10\times 80.0kPa=8kPa
