<span>The Mass Of The Products Of A Chemical Reaction Is equal to The Mass Of The Reactants.</span>
Answer:
0.220 mol He
Explanation:
Hello,
Based on the ideal gas equation of state:
Best regards.
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.
