Answers are:
1) ΔH is negative because that is combustion reaction and heat is released, enthalpy of combustion is -2877.5 kJ/mol.
2) ΔS is positive, because there more molecules on the right side of balanced chemical reaction, standard molar entropy is <span>310.23 J/mol</span>·<span>K.
</span>3) ΔG = ΔH - TΔS.
ΔG = -2877.5 kJ/mol - 298 K · 310.23 J/mol·K.
ΔG = -2969.95 kJ/mol.
Hello!! Your atomic mass will be found at the bottom of each element. The atomic mass of Nitrogen is 14.007. Have a great day!!
Answer:
yes
Explanation:
because this is a neutralization reaction that yield salt and water
Since the water is gaining heat from its surroundings, the reaction is endothermic
