The chemical reaction represented by the following balanced chemical equation takes place in aqueous
solution: MnO4 + 5 Fe2+8H - Mn2 + 5 Fe3+ 4H2O
When the disappearance of the permanganate ion, MnO4, is monitored, the rate of reaction for the
consumption of the ion is 4.0x10^2 mol/L. s. Calculate the reaction rate for all other reactants and products.

Explanation:

MnO₄⁻ + 5 Fe2⁺ + 8H⁺ = Mn⁺² + 5Fe⁺³ + 4H₂O.

- d [MnO₄⁻ ] / dt = 4 x 10² mol /L.s.

- [ Fe²⁺ ] / dt = 5 x - d [MnO₄⁻ ] / dt

= 5 x 4 x 10² mol /L.s.

20 x 10²

- d [ H⁺] / dt = 8 x - d [MnO₄⁻ ] / dt

= 8 x  4 x 10²

= 32 x 10² mol /L.s.

+d [ Mn⁺² ] / dt = - d [MnO₄⁻ ] / dt

= 4 x 10² mol /L.s

+d [ Fe⁺³ ] / dt = 5 x - d [MnO₄⁻ ] / dt

= 20 x 10² mol /L.s

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
