For Plato users :

The equilibrium SHIFTS LEFT. Simultaneously, there’s an increase in the REVERSE reaction.

To counter the removal of A the equilibrium change by shifting toward the left

explanation

If the reaction is at equilibrium and we alter the condition a new equilibrium state is created

The removal of A led to the shift of equilibrium toward the left since it led to less molecules in reactant side which favor the backward reaction.( equilibrium shift to the left)

trans-2-Butene does not exhibit a signal in the double-bond region of the spectrum (1600–1850 cm-1); however, IR spectroscopy is

spayn [35]

Answer:

The other signal that would indicate the presence of a C= C bond appears close to 3100 $cm^{-1}$ .

Explanation:

Bands that appear above 3000 $cm^{-1}$ are often unsaturation diagnoses suggest. The band at 3000- 3100 $cm^{-1}$ is characteristics for C-H stretching frequencies and normally is overlaps with the ones for alkanes because it is a band of weak intensity.

How many electrons are transferred in the given redox reaction? Zn+2AgNO3⟶2Ag+Zn(NO3)2

Vsevolod [243]

Answer:

2 electrons are transfered in this reaction.

Explanation:

Oxidation is a reaction where an atom, ion, or molecule loses electrons, while reduction corresponds to the electron gain of an atom, ion, or molecule.

In an oxidation-reduction reaction two simultaneous processes take place, oxidation and reduction.

So, oxidation-reduction (redox) reactions involve the transfer of electrons between chemical species. They are also called electron transfer reactions since the particle that is exchanged is the electron.

In this case:

Zn(s) ⇒ Zn²⁺(aq) + 2 e⁻

2 Ag⁺ (aq) + 2 e⁻ ⇒ 2 Ag(s)

So, zinc metal loses two electrons to form the zinc(II) ions, while the two silver ions each gain one electron to form two silver metal atoms.

Then, Zn is a reducing agent (The reducing agent is the one that provides the electrons, oxidizing itself), AgNO3 is an oxidizing agent (The oxidizing agent is the one that traps the electrons, reducing itself).

Finally, you can see that 2 electrons are transfered in this reaction.

Lake Minnetonka in Southern Minneosta is buffer solution

Explanation:

One can conclude from the observation that Lake Minnetonka is a buffer solution. A buffer solution is a special solution that resist changes in pH or pOH when a small amount of an acid or base is added.

Buffers are solutions in equilibrium with a fairly constant pH.
They are aqueous solutions containing weak acids and their salts or weak bases and their salts.
Since the pH of water sample from Lake Minnetonka did not change, it is a buffer.
