The balanced equation for the syntheis of Iron (I) oxide is below:

Shtirlitz [24]

Answer:

Option B. 2.7 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.

Explanation:

The balanced equation for the reaction is given below:

4Fe + 3O2 —> 2Fe2O3

From the balanced equation above,

4 moles of Fe reacted with 3 moles of O2 to produce 2 moles of Fe2O3.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

4 moles of Fe reacted with 3 moles of O2.

Therefore, 5.4 moles of Fe will react with = (5.4 × 3)/4 = 4.05 moles of O2.

Thus, we can see that only 4.05 moles out of 4.7 moles of O2 given is needed to react completely with 5.4 moles Fe. Therefore, Fe is the limiting reactant and O2 is the excess reactant.

Finally, we shall determine the maximum amount of Fe2O3 produced from the reaction.

In this case, the limiting reactant will be use because it will produce the maximum amount of Fe2O3 as all of it is used up in the reaction.

The limiting reactant is Fe and the maximum amount of Fe2O3 produced can be obtained as follow:

From the balanced equation above,

4 moles of Fe reacted to produce 2 moles of Fe2O3.

Therefore, 5.4 moles of Fe will react to produce = (5.4 × 2)/4 = 2.7 moles of Fe2O3.

Summary:

Limiting reactant => iron (Fe)

Maximum amount of Fe2O3 produce = 2.7 moles

What percent of the moon is visible in the last quarter moon phase shown? A) 0% B) 25% C) 50% D) 100%

loris [4]

Answer:

As you can see from the picture, about half the moon is visible.

Half = 1/2 = 50%

So, C is the correct answer.

Let me know if this helps!

For a particular redox reaction, bro− is oxidized to bro−3 and fe3 is reduced to fe2. complete and balance the equation for this

Mamont248 [21]

The balanced chemical equation in a basic solution will be,

$BrO^{-} + 4OH^{-} +4Fe^{+3}$ → $BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}$

The reaction in which oxidation and reduction reaction takes place simultaneously is called redox reaction or oxidation - reduction reaction .

Rules for the balanced chemical equation in a basic solution are :

First write half - reaction.
Now balancing the main atoms in the reaction
Now balancing the hydrogen and oxygen atoms on both sides of the reaction .
If the oxygen atoms is not balance on both side then add water molecule at that side at that side where more number of oxygen atom is present.
If the hydrogen atom are not balanced on both side then add hydroxide ion at that side of where less number of hydrogen are present.
Now at last balance the charge.

Therefore, the balanced chemical equation in a basic solution will be,

$BrO^{-} + 4OH^{-} +4Fe^{+3}$ → $BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}$
