The answer is because they are magnetic B.
Answer:
A. Energy is released
Explanation:
Energy is only released when chemical bonds are formed.
Answer:
First option:
[NH3]2 / [N2][H2]3
Explanation:
First of all we need to determine the reaction:
N₂(g) + 3H₂(g) → 2NH₃(g)
1 mol of nitrogen can combine with 3 moles of hydrogen to produce 2 moles of ammonia.
Remember that Kc has to involve Molar concentrations of products / reactants
Concentration must be elevated to the stoichiometry coefficient
Kc for the reaction is: [NH₃]² / [N₂] . [H₂]³
Its called D. evaporation
when mercury receives enough thermal energy that is converted into kinetic energy so high that it breaks the weak bonds holding the atoms together and causes them to become gaseous
