8H⁺ + 5Fe²⁺ + MnO₄⁻ ⇒ Mn²⁺ + 5Fe³⁺ + 4H₂O
<span>
According to the reaction, Fe</span>²⁺ and MnO4⁻<span> have following stoichiometric ratio:
n(</span>Fe²⁺) : n(MnO4⁻) = 5 : 1
n(MnO4⁻) = n(Fe²⁺) / 5
<span>
So, for each mole of </span>Fe²⁺ it is needed 1/5 moles of MnO4⁻.<span>

Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the
total value could be found from B-Y. C is the value of your energy of
your products. X is your delta H value. So in this, your products are
higher energy than the reactants, so H is + and e2-E1 is positive so E2
>E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)

Answer:
The amount of thermal energy stored in an object depends on three things.
- The mass of the object.
- The temperature of the object.
- The amount of energy that the particular material stores per degree of temperature.
Answer:
D
Explanation:
An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.
<span>The noble gases are the six elements that make up Group 18 of theperiodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). At one time, this family of elements was also known as the rare gases.</span>
