The answer is the second one: carbon dioxide and methane.

Explanation for each option:

  1. Nitrogen and helium: Incorrect. Nitrogen is the most abundant gas in the Earth's atmosphere, but it does not significantly contribute to the greenhouse effect. Helium is a noble gas and also does not contribute to the greenhouse effect.

  2. Carbon dioxide and methane: Correct. Both carbon dioxide (CO2) and methane (CH4) are significant greenhouse gases. They trap heat in the atmosphere, contributing to global warming and climate change.

  3. Carbon dioxide and helium: Incorrect. While carbon dioxide is a greenhouse gas, helium is not. Helium is a noble gas and does not contribute to the greenhouse effect.

  4. Nitrogen and methane: Incorrect. While methane is a greenhouse gas, nitrogen is not. Nitrogen is abundant in the atmosphere but does not contribute to the greenhouse effect.

In summary, carbon dioxide and methane are both key contributors to the greenhouse effect.

Delta G - Delta G^circ = Delta G^circ + R T ln Q - Delta G^circ This results in: (Delta G - Delta G^circ) = R T ln Q Step Two Multiply both sides of the equation by the same expression: times(Delta G - Delta G^circ) = times R T ln Q Drag and drop your selection from the following list to complete the answer: -RT, 1/(RT) RT, -1/(RT)
