The average kinetic energy of translation of oxygen molecules in the gas is 5.05 × 10⁻²¹
The given data is
n = 2
v = 20
P = 92
K.E = 3 / 2 KbT
= 3 / 2 PV / N
= 3 / 2 Pv / nNa
K.E = 3 / 2 × 9 × 1.013 × 10⁵ × 20 × 10⁻³ / 2 × 6.022 × 10²³
K. E = 5.05 × 10⁻²¹ J
<h3>Average kinetic energy</h3>
The average kinetic energy (K) is equal to one half of the mass of each gas molecule times the RMS speed squared
Hence, the average kinetic energy is 5.05 × 10⁻²¹ J

Given that,
Work done by the system = 125 J
Energy released when it cools down = 438 J
To find,
The change in internal energy.
Solution,
As heat is released by the system, Q = -438 J
Work done by the system, W = -125 J
Using the first law of thermodynamics. The change in internal energy is given by :
So, the change in internal energy is 563 J.
Soda ash which is also referred to as sodium carbonate with a chemical formula (NaCO3) has the following chemical formula
The melting point of 851 degrees
The molecular weight of 105.98
Its density at 25 degrees is =2.53 g/cm^3
Its specific heat capacity at 25 degrees = 0.249 cal/gm/ 0c
Answer:
Remove the already produced water and allow the reaction to reach equilibrium again.
Explanation:
<em>According to Le Chatelier principle, when a reaction is in equilibrium and one of the factors that influence the rate of reaction is altered, the equilibrium will shift so as to annul the effects of the change.</em>
If the product is continuously being removed from a reaction that is in equilibrium, more product will continued to be formed in another to annul the effect of reduction in the concentration of product.
Hence, in order to maximize production of water in the reaction, the product (water) needs to be removed and the reaction allowed to reach equilibrium again.
