The correct answer is option 3. There are no attractive forces between the gas particles in an ideal gas. For an ideal gas to be achieved, the molecules are far from each other as possible where no attraction or collisions happen with each molecule.
Answer:
0.146 M
Explanation:
Equation for the reaction :
2A(aq) ↔ B(aq) + C(aq)
= 65
Molar concentration of A = 
= 2.5 M
2A(aq) ↔ B(aq) + C(aq)
Initial 2.50 0 0
Change - 2x + x + x
Equilibrium 2.50 - 2x +x +x

![65 = (\frac{[x]}{[2.5-2x]})^2](https://tex.z-dn.net/?f=65%20%3D%20%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2)
![\sqrt 65 = \sqrt {(\frac{[x]}{[2.5-2x]})^2}](https://tex.z-dn.net/?f=%5Csqrt%2065%20%3D%20%20%5Csqrt%20%7B%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2%7D)
8.062(2.5 - 2x) = x
20.155 - 16.124x = x
20.155 = 16.124x+x
20.155 = 17.124x
x = 
x = 1.177
[A] = 2.5 - 2x
= 2.5 - 2(1.177)
= 0.146 M
Therefore, the equilibrium concentration of A = 0.146 M
Answer:
The group 14 elements all have ns2np2 valence electron configurations. All form compounds in which they formally lose either the two np and the two ns valence electrons or just the two np valence electrons, giving a +4 or +2 oxidation state, respectively

The answer is; D
Solvation is the process by which the molecules of a solute interact with those of a solvent to form solvates. The interaction involves the formation of temporary bonds between the molecules of the elements. These bonds in this rection absorb energy from the atmosphere hence the reaction feels cold to the touch. This is called an endothermic reaction.
