not sure of the answer not in scientific notation :(
hopefully i could help
Answer:
Option A 0.5424 M
Explanation:
To do this, let's write the reaction again and see the mole ratio:
14H⁺ + 6Fe²⁺ + Cr₂O₇⁻ ---------> 2Cr³⁺ + 6Fe³⁺ + 7H₂O
According to this reaction, we have a mole ratio between the dicromate and iron of 1:6. In other words, 6 moles of dicromate reacts with only 1 mole of iron, therefore we can use the following expression:
nFe = 6 * nCr₂O₇
This is a REDOX reaction, where Iron is being oxidized while cromium is being reduced. Now, we have the concentrations and volume, let's express the moles in function of concentration and volume:
M₁V₁ = 6M₂V₂
Replacing the given data above and solving for concentration of iron (M₁)
M₁ = 6 * 45.20 * 0.1 / 50
M₁ = 0.5424 M
This is the concentration of the iron solution
The reaction that takes place in a nuclear fission reactor is as follows: 235/92 U + 1/0n 94/36Kr + 139/56 Ba + 3/0n.
<h3>What is a nuclear fission reactor?</h3>
A nuclear fission reactor is the place where nuclear chain reactions occur that produce energy by fission.
Nuclear fission is the nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.
Therefore, the option that involves the splitting of atoms into smaller ones is as follows: 235/92 U + 1/0n 94/36Kr + 139/56 Ba + 3/0n.
