The number of mole of oxygen needed is of 0.080 mole.
To solve this question, we'll begin by writing the balanced equation for the reaction. This is illustrated below:
<h3>CH₃COOH + 2O₂ —> CO₂ + 2H₂O</h3>
From the balanced equation above,
2 moles of O₂ reacted to produce 2 moles of H₂O.
Finally, we shall determine the number of mole of O₂ needed to produce 0.080 mole of H₂O. This can be obtained as follow:
From the balanced equation above,
2 moles of O₂ reacted to produce 2 moles of H₂O.
Therefore,
0.080 mole of O₂ will also react to produce 0.080 mole of H₂O.
Thus, 0.080 mole of oxygen, O₂, is needed for the reaction.

Answer: Positive effects: mass production of fertilizers, alkaline cleansers, refrigerant gas, dyes, explosives
Negative effects: heath problems, negative effects on soil organisms and soil organic matter, imbalances to the nitrogen cycle, high fossil fuel energy inputs, production of deadly weapons
Explanation:
The Haber process (also called Haber Bosch process) is used to produce ammonia from nitrogen and hydrogen under the high pressure. Basically, it's an artificial nitrogen fixation process. This method has both positive and negative effects on modern society.
Positive sides: ammonia is mainly used for mass production of fertilizer, which allows more food for everyone. It can be used for production of alkaline cleansers, refrigerant gas, dyes and explosives. Ammonia is also used in production of synthetic polymers, due to its role in the manufacturing of cyanide.
Negative sides: ammonia is a toxic gas, it can irritate eyes and lungs. Because of that, the excess nitrogen in soil and water coming from synthetic fertilizers can cause health problems. It is harmful for humans and animals, but it can also be harmful for plants. Environmental factors are also important. Because of the mass fixation, there is imbalance in the earth’s nitrogen cycle. Also, fossil fuels are used as a source of power for machinery in Haber's process, which increases emissions into the atmosphere. And, at least ammonia is a major component of weapons including great number of bombs.
D. Volcanoes formed most of them through eruption.
