Answer:
The correct answer will be-gas absent in primordial atmosphere (oxygen).
Explanation:
The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.
Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.
Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.

Answer:
Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.
Explanation:
Hope this helps!
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
