If the temperature is increased then reaction will shift to the left because heat is absorbed.
<h3>What is equilibrium state?</h3>
Equilibrium of any reaction is that state in which concentration of reactant and concentration of product will be constant.
Given chemical reaction is:
A(g) + 2B(g) ⇄ C(g) + D(g)
From the equilibrium state reaction will move only that side which will contribute to maintain the stable state. In the forward reaction heat is released as mention in the question. So, when the temperature of reaction is increased then it shifts towards the left side by absorbing the heat and maintain the stability.
Hence, option (2) is correct, i.e. It will shift to the left because heat is absorbed.

Answer:
Sol is a colloidal suspension with solid particles in a liquid. Foam is formed when many gas particles are trapped in a liquid or solid. Aerosol contains small particles of liquid or solid dispersed in a gas. While solid solution contain solid as solute in either solid, liquid or gas.
In light reactions there is successful photosynthesis due to the fact one of the primary reactants for photosynthesis in the first place. At the end of the light reaction, there will be the normal photosynthesis products formed which are glucose and oxygen. For the dark reaction no products will be formed
Answer:
pKa = 3.675
Explanation:
∴ <em>C</em> X-281 = 0.079 M
∴ pH = 2.40
let X-281 a weak acid ( HA ):
∴ HA ↔ H+ + A-
⇒ Ka = [H+] * [A-] / [HA]
mass balance:
⇒<em> C</em> HA = 0.079 M = [HA] + [A-]
⇒ [HA] = 0.079 - [A-]
charge balance:
⇒ [H+] = [A-] + [OH-]... [OH-] is negligible; it comes from to water
⇒ [H+] = [A-]
∴ pH = - log [H+] = 2.40
⇒ [H+] = 3.981 E-3 M
replacing in Ka:
⇒ Ka = [H+]² / ( 0.079 - [H+] )
⇒ Ka = ( 3.981 E-3 )² / ( 0.079 - 3.981 E-3 )
⇒ Ka = 2.113 E-4
⇒ pKa = - Log ( 2.113 E-4 )
⇒ pKa = 3.675
I have not taken Chemistry in a year but I remember that if you look at a periodic table there are certain sections for polar and non polar elements. I dont know if you have learned that yet
