iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction - comparatively speaking, ferrous compounds are easier to hydrolyze than their ferric counterparts.
<h3>What is Redox reaction ?</h3>
Compared to ferric oxide, ferrous oxide is more basic in makeup. Comparatively speaking, ferrous compounds are more ionic than their ferric counterparts. Due to the fact that ferrous compounds are more ionic than their corresponding ferric ones, they are less volatile.
The greater positive charge of ferric compounds, however, makes them easier to hydrolyze than the comparable ferrous ones.
The quantity, kind, and distances of the iron atom's neighbors all contribute to their stability. Because each Fe atom is only weakly linked together by three electrons, which makes them susceptible to being dragged away by strong electronegative neighbors like oxygen, both types of ions are stable.

Answer:
You take the atomic, or proton number of the element, and you subtract it from the element's mass number.
Answer:
B. mass and height have the same effect on gravitational potential energy.
Explanation:
Both mass and height have the same effect on the gravitational potential energy of body.
Gravitational potential energy is the energy of a body due to that of another body. It usually the energy at rest in a body.
It is mathematically expressed as;
G.P.E = m x g x h
m is the mass
g is the acceleration due to gravity
h is the height
We see that both the height and mass are directly proportional to the gravitational potential energy and as such, they have the same effect.
Answer:
B as all the forces cancel out
Explanation:
20-20=0
25-25=0
Answer:
30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.
Explanation:
Let volume of the 40% acid solution be x.
Let volume of the 60% acid solution be y.
Volume of solution formed after mixing both solution = 40 L
x + y = 40 L..[1]
Volume of acid 40% solution = 40% of x= 0.4x
Volume of acid 60% solution = 60% of y= 0.6y
Volume of acid formed = 45% of 40 L = 
..[2]
Solving [1] and [2]
x = 30 L , y = 10 L
30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.
