The best answer choice here would be 'Combination'
Answer: C. The number of atoms of each element is the same on each side of the equation.
Explanation:
The Law of Conservation of Matter shows that it is not possible for matter to either be created nor for it to be destroyed so the number of atoms of each element on the reactant side of the equation must equal the number of atoms in each element on the product side of the equation.
This is why the following equation is incomplete:
H₂ + O₂ ⇒ H₂O
The oxygen atoms are not the same on either side.
Equation will therefor have to be balanced which will make it:
2H₂ + O₂ ⇒ 2H₂O
Notice now that atoms are the same on both sides.
The answer to your question is: Chemical Reaction.
The nucleus is the center of the atom where the protons and neutrons can be found.
Answer:

Explanation:
Hello!
In this case, for the undergoing chemical reaction at equilibrium:

Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:

Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
