<u>Answer:</u> The half reactions are written below.

<u>Explanation:</u>

Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

We are given a chemical cell which is Fe-Sn cell. The half reaction follows:

<u>Oxidation half reaction:</u> $Fe\rightarrow Fe^{2+}+2e^-;E^o_{Fe^{2+}/Fe}=-0.44V$

<u>Reduction half reaction:</u> $Sn^{2+}+2e^-\rightarrow Sn;E^o_{Sn^{2+}/Sn}=-0.14V$

The substance having highest positive $E^o$ potential will always get reduced and will undergo reduction reaction. Here, zinc will always undergo reduction reaction will get reduced.

<u>Total cell reaction:</u> $Fe+Sn^{2+}\rightarrow Fe^{2+}+Sn$

Hence, the half reactions are written above.

In a reaction 4 NH3 + 5 O2 → 4 NO + 6 H2O, 1 mole of ammonia reacts with 2 moles of oxygen. Which of these is correct after the

Vsevolod [243]

Answer:

<em><u>Option B) All the ammonia is consumed</u></em>

Explanation:

<u>1. Balanced chemical equation (given):</u>

$4NH_3+5O_2\rightarrow 4NO+6H_2O$

<u>2. Theoretical mole ratios:</u>

$4molNH_3:5molO_2:4molNO:6H_2O$

<u>3. Limiting reactant:</u>

When 1 mole of ammonia is combined with 2 moles of oxygen, the mole ratio is:

$1molNH_3:2molO_2$

Hence, one of the reactants will be completely consumed (the limiting reactant) and, after completion, an excess of the other will remain unreacted.

You need to compare the the actual ratio with the theoretical ratio.

4/5 > 1/2

Hence, NH₃ is in less proportion with respect to oxygen than what is theoretically needed, and the former is the limiting reactant.

Therefore, the 1 mole (all) of ammonia will be consumed, while some oxygen will remain as excess. This is described by the option B) All the ammonia is consumed.

<u />

<u>4. Analyze the other options:</u>

The amount of oxygen that will react is:

$1molNH_3\times5molO_2/4molNH3=5/4molO_2$

And the amount that will remain is:

$2molO_2-4/5molO_2=6/5molO_2$

Neither option A) nor C) describe that situation.

The amount of water produced is:

$1molNH_3\times 6molH_2O/4molNH_3=1.5molH_2O$ , which is not described by the option D).

Hence, the correct answer is the option B) All the ammonia is consumed.

A - ion (negative ion, one with extra negative charge)?

bekas [8.4K]

Answer:

That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
