Answer:d
Explanation:Since the earth would be closer to the sun the ozone layer would not be able to handle the more powerful ultra violet rays making the earth to hot.
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.
Radon is <span>not a source of air pollution related to human activities</span>
Im pretty sure th answer is D: temp differences on earth surface
