Answer:
C - Cl = Polar (Chlorine has an electronegativity of 3.16 and Carbon has 2.55. The difference between the two determines if the bond is polar or non polar, and the difference is 0.61 which means its polar)
Br - Br = Non-polar (Diatomic molecules are non-polar)
N - O= Non-polar ( The electronegativity difference is 0.4, making it non-polar)
P - Cl= Polar (The difference in electronegativity between them is 0.97, making it polar)
Answer:
Explanation:
Hello!
In this case, for the described chemical reaction, we find it is:
Because it says that the iron is dissolved in a strong acid which provides addition hydrogen ions to the reaction media. Thus, for the questions attached on the figure we find:
- This a REDOX reaction because we see iron is being oxidized from 2+ to 3+ and manganese reduced from +7 to +2.
- Since it is a redox reaction and the oxidized species is that undergoing an oxidation number increase, we evidence iron goes from +2 to +3, which means iron is the oxidized species.
- In this case, for the used 59.2 mL (0.0592 L) of the 0.2000 M solution of potassium permanganate, we can compute the consumed grams of iron via stoichiometry including the 5:1 mole ratio between them in the chemical reaction:
It means that the percent of iron in that sample is:
Best regards.
