Describe the reactions during the electrolysis of water in an electrolytic cell. Group of answer choices Oxygen and hydrogen are
Ann [662]

Answer:

Oxygen is oxidized and hydrogen is reduced.

Explanation:

Let's consider the redox reaction during the electrolysis of water in an electrolytic cell.

2 H₂O ⇒ 2 H₂ + O₂

The corresponding half-reactions are:

2 e⁻ + 2 H₂O ⇒ H₂ + 2 OH⁻

2 H₂O ⇒ O₂ + 4 H⁺ + 4 e⁻

Oxygen is oxidized since its oxidation number increases from -2 to 0.

Hydrogen is reduced since its oxidation number decreases from +1 to 0.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N2(g)+3H2(g)⟶2NH3(g) Ass
yaroslaw [1]

Answer:

moles of ammonia produced = 0.28 moles

Explanation:

The reaction is

N_{2}(g)+3H_{2}(g) --> 2NH_{3}(g)

As per equation, one mole of nitrogen will react with three moles of hydrogen to give two moles of ammonia

So 0.140 moles of nitrogen will react with = 3 X 0.140 moles of Hydrogen

             = 0.42 moles of hydrogen molecule.

this will give 2 X 0.140 moles of ammonia = 0.28 moles of ammonia

the moles of ammonia produced = 0.28 moles

Here the nitrogen is limiting reagent.

pishuonlain [190]

Answer:

<em>The correct option is B) a bridge to connect two landmasses over a stretch of water.</em>

Explanation:

A civil engineer is a person who deals with the designing and construction of infrastructure projects like the construction of roads, buildings, bridges, airports, tunnels etc. Civil engineering is one of the most oldest disciplines in engineering and it is broken into many sub-disciplines. A civil engineer might work for a private or a government-based organization. Hence, among the options mentioned in the question, the construction of a bridge is the most likely function of a civil engineer.
