Which molecule is most responsible for the adverse effects of pollution and deforestation on Earth's climate?
A. hydrogen gas
B. carbon dioxide
C. iron oxide
D. ammonia

B, carbon dioxide

Explanation:

It is released through many human activities such as burning fossil fuels, deforestation, land use, and even respiration.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

i'm wiling to try and you : )
