Answer:
B. 091
Explanation:
When we add these two equilbria, the equilibrium constant for the resultant equilibrium is the product of the first two.
Notice that when we add the first two reactions in this question, we obtain the equilibrium for which we are seeking its equilibrium constant. Therefore,
A(g) + B(g) ? AB(g) Kc₁ = [AB] / [A][B]
+
AB(g) + A(g) ? A2B(g) Kc₂ = [A₂B] /[ AB][A]
_________________________________
2 A(g) + B(g) ⇄ A₂B(g) Kc₃ = [A₂B] / [A]²[B]
Kc₁Kc₂ = [AB] / [A][B] x [A₂B] / [AB][A] = [A₂B] / [A]²[B]
Thus,
Kc₃ = 0.24 x 3.8 = 0.91
This procedure is not limited to two reaction, it could done for more than two, as long as the desired equilibrium is the desired one.
If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases;
- Its temperature increases
- The space between particles increases
- The particles move faster
Explanation:
As heat energy is applied to a substance, its temperature increases. The molecules of the gain more kinetic energy and the bombardment between the molecules increase with frequency and energy. The distance between the molecules also increases and this is attributed to the expansion of substances when heated. This continues until temperatures are reached where the kinetic energy of the molecules is high enough to overcome the intermolecular forces between the molecules and the substance changes phase.

Answer:
50
Explanation:
so you'll have to apply Newton's 2nd law which is F=ma and then substitute the values that you already have in the question as in, the force is 200 and you'll have to find the acceleration by working it out which is 4m/s² and then find the mass by dividing 200 by 4 so the actual mass is 50kg ✌️❤️
