Answer:
nitrogen is the answer because of the same position of group in periodic table
Yes this statement is true because the concentration is two help determine whether the reaction is moving forward or backwards direction
Here it is at standard condition and delta g not is always the same because it denote that the reactant/product are at standard temperature or product as the reaction goes toward equilibrium delta g change because reaction is proceeding forward and delta g not is standard change in free energy between reactant and product. delta g is used to find gibbs free energy in nonstandard conditions while delta g naught is used to determine gibbs free chemical reaction energy under normal conditions. that's why this statement is true.

Answer: option D) energy was absorbed and entropy increased.
Explanation:
1) Given balanced equation:
2H₂O (l) + 571.6 kJ → 2 H₂ (g) + O₂(g).
2) Being the energy placed on the side of the reactants means that the energy is used (consumed or absorbed). This is an endothermic reaction.
So, the first part is that energy was absorbed.
3) As for the entropy, it is a measure of the disorder or radomness of the system.
Since, two molecules of liquid water were transformed into three molecules of gas, i.e. more molecules and more kinetic energy, therefore the new state has a greater degree of radomness, is more disordered, and you conclude that the entropy increased.
With that, you have shown that the right option is D) energy was absorbed and increased.
