The  standard cell potential is obtained from the equation of the reaction.

<h3>What is the  standard cell potential?</h3>

The  standard cell potential is obtained from the equation of the reaction. Now we have the overall cell equation as from the half reactions as;

Oxidation half reaction;

Al(s) --->Al³+ (aq) + 3 e

Reduction half equation;

Cu²+ (aq) + 2 e →→ Cu(s)

Standard cell potential Eºcell = 0.34V - (-1.66 V) = 2 V

Now;

ΔG = -nFEcell

ΔG = -(2 * 6 * 96500 * 2)

ΔG = -2316kJ

E = 2 - 0.0592/6 log [0.0025]/[3.5 M]

E = 2 + 0.031

E = 2.031 V

1. What type of wave is shown below?
svlad2 [7]

Answer : The correct option is, transverse wave.

Explanation :

Longitudinal waves : It is defined as the waves in which the particles of the medium move in the direction of the wave.

Transverse wave : It is defined as the waves in which the particles of the medium travel perpendicularly to the direction of the wave.

Surface wave : It is defined as a combination of transverse and longitudinal waves.

From the given image we conclude that, this illustration depict the transverse wave because the particles of the medium move perpendicularly to the direction of the wave.

Hence, the type of wave is, transverse wave

Carlos is making phosphorus trichloride using the equation below.
hjlf

Answer:

C.) 2

Explanation:

Chemical equations, in a way, can be seen as algebraic equations. Cl2 is a molecular structure, so, there are two Cl atoms. 3Cl2 means 3, Cl2 molecules. So, if we think of it as adding up all the atoms, we will get, 2 P atoms and 6 Cl atoms. Now to convert. The Law of the Conservation of Mass basically says you can't add or subtract atoms out of nowhere, so the number of atoms has to stay the same when it's being converted. We need to place a coefficient with PCl3. If we look at PCl3, it shows us that there are three Cl atoms and one P atom. And looking back at how many atoms there were on the left side of the equation, we just need to double the atoms of atoms so it will be equal. So, the answer is C.) 2

What would happen to a weak base dissociation equilibrium if more products
Elina [12.6K]

Answer:

Both B and D are correct.

Explanation:

B + H₂O ⇌ BH⁺ + OH⁻

If you add more products, the position of equilibrium will shift to the left to decrease their concentrations (Le Châtelier's Principle). The concentration of reactants will increase, but the equilibrium concentrations of products will also be higher than they were initially.

A is wrong. The equilibrium constant is a constant. It does not change when you change concentrations.

C is wrong. Per Le Châtelier's Principle, the concentrations must change when you ad a stress to a system at equilibrium.

(This is a poorly-worded question. "They" are probably expecting answer D.)
