Einstein’s Theory of Relativity was built on the research and ideas of other scientists. The Theory of Relativity proposes that the speed of light is aconstant. The statement that explains why this is considered to be a scientific theory is that the majority of the scientific community voted on this theory over other possible explanations.

Free-energy change, ΔG∘, is related to cell potential, E∘, by the equation ΔG∘=−nFE∘ where n is the number of moles of electrons

elena-s [515]

Answer:

-372000 J or -372 KJ

Explanation:

We have the electrochemical reaction as;

Mg(s) + Fe^2+(aq)→ Mg^2+(aq) + Fe(s)

We must first calculate the E∘cell from;

E∘cathode - E∘anode

E∘cathode = -0.44 V

E∘anode = -2.37 V

Hence;

E∘cell = -0.44 V -(-2.37 V)

E∘cell = 1.93 V

n= 2 since two electrons were transferred

F=96,500C/(mol e−)

ΔG∘=−nFE∘

ΔG∘= -( 2 * 96,500 * 1.93)

ΔG∘= -372000 J or -372 KJ

The valencies of metal a,band c are 1,2,3respectively what is the formula of hydroxide of a

Luba_88 [7]

The formula of metal hydroxides for

A) metal A = A(OH)

B) metal B = B(OH)₂

C) metal C = C(OH)₃

<h3>What are hydroxides?</h3>

When a metal's oxide combines with water, a hydroxide is created.

The general formula of hydroxide is:

M(OH)ₙ

where n is the valency of metal.

OH has a valency of -1

A) The formula of hydroxide of metal A:

The valency of metal A is 1

This means, here, n = 1

Therefore, the metal hydroxide formula will be = A(OH)

B) The formula of hydroxide of metal B:

The valency of metal B is 2

This means, here, n = 2

Therefore, the metal hydroxide formula will be = B(OH)₂

C) The formula of hydroxide of metal C:

The valency of metal C is 3

This means, here, n = 3

Therefore, the metal hydroxide formula will be = C(OH)₃
