Answer:
The statement describes a process involved in the evolution of Earth’s early atmosphere would be:
Cyanobacteria transformed carbon dioxide in the atmosphere into oxygen during photosynthesis

The empirical formula CH₂O has a mass [(12 × 1) + (1 × 2) + (16 × 1)] = 30 g/mol
If the empirical formula is 30 g/mol,
and the molecular formula is 60 g/mol
Then the multiple is = 60 g/mol ÷ 30 g/mol
= 2
Therefor the molecular formula is 2(CH₂O) = C₂H₄O₂ (OPTION 2)
Answer: The correct answer is absorbed.
Explanation:
Bond formation is a type of exothermic process. In these reactions when two atoms come close to each other, energy is released in this process.
On the other hand, in the breaking of bond, energy is required because the atoms are to be separated from each other. This is a type of endothermic process. So, the energy must be absorbed.
Hence, the correct answer is absorbed.
