Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process

Arlecino [84]

Lithium metal reacts with nitrogen gas to form lithium nitride the balanced chemical equation will be 6Li + N₂ → 2Li₃N.

<h3>What is a balanced chemical reaction?</h3>

In a balanced chemical reaction, the number of moles that are present at the side of the reactant must be always equal to the side of product formation this is known as a balanced chemical equation.

The balanced chemical reaction will be 6Li + N₂ → 2Li₃N.

Here 6 moles of lithium is reacting with one nitrogen but as it is in gaseous state it is N₂ after reacting with lithium it will give two moles

Therefore, balanced equation will be 6Li + N₂ → 2Li₃N

How many seconds are in the month of may? (May has 31 days)

creativ13 [48]

Answer:

92,565,504,000 seconds in 31 days

Explanation:

multiply the days by 24 hours

31 * 24= 744

multiply the hours in 1440 minutes

1071360 minutes

now multiply that by 86400 seconds

92,565,504,000 seconds in 31 days

spontaneous redox reaction happens between zinc (Zn) and magnesium (Mg) in an electrochemical cell. (6 points) i. Use the reduct

aev [14]

Answer:

For (i): Magnesium is getting oxidized and zinc is getting reduced.

For (ii): The half reactions are given below.

For (iii): Magnesium will act as anode and zinc act as cathode.

Explanation:

For (i):

$E^o_{(Mg^{2+}/Mg)}=-2.37V\\E^o_{(Zn^{2+}/Zn)}=-0.76V$

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.

Magnesium will undergo oxidation reaction and will get oxidized.

For (ii):

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.

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

Oxidation half reaction: $Mg\rightarrow Mg^{2+}+2e^-$

Reduction half reaction: $Zn^{2+}+2e^-\rightarrow Zn$

For (iii):

Oxidation reaction always occurs on anode side and thus, magnesium is acting as anode.

Reduction reaction always occurs on cathode side and thus, zinc is acting as cathode.
