For the oxidation–reduction reaction equation

Chemistry

In the formation of 1 formula unit of ScBr₃, 3 electrons are transferred.

Let's consider the following balanced redox reaction.

2 Sc + 3 Br₂ ⟶ 2 ScBr₃

We can identify both half-reactions.

Oxidation: 2 Sc ⟶ 2 Sc⁺³ + 6 e⁻

Reduction: 6 e⁻ + 3 Br₂ ⟶ 6 Br⁻

As we can see, 6 electrons are involved in the formation of 2 formula units of ScBr₃. Thus, 3 electrons are involved in the formation of 1 formula unit of ScBr₃.

In the formation of 1 formula unit of ScBr₃, 3 electrons are transferred.

What is one benefit associated with nuclear fission
Julli [10]
Nuclear fission share a number of advantages. These include less emission of greenhouse gases, relatively lower operating costs, this process is well understood. Also, since the population is rising, the demand is as well rising and with the aid of this process we can meet that high demand.

snow_tiger [21]

Answer:

E. Q < K and reaction shifts right

Explanation:

Step 1: Write the balanced equation

A(s) + 3 B(l) ⇄ 2(aq) + D(aq)

Step 2: Calculate the reaction quotient (Q)

The reaction quotient, as the equilibrium constant (K), only includes aqueous and gaseous species.

Q = [C]² × [D]

Q = 0.64² × 0.38

Q = 0.15

Step 3: Compare Q with K and determine in which direction will shift the reaction

Since Q < K, the reaction will shift to the right to attain the equilibrium.
