What is the shorthand notation (i.e., line notation) that best represents a complete electrochemical cell for the following galv

anic cell reaction?
Sn^2+ (aq) + F2 (g) → Sn^3+ (aq) + 2F^− (aq)
O Pt(s) | Sn^2+ (aq), Sn^3+ (aq) || F2 (g) F^-(aq)| C(s)
O F2(g)|F^- (aq) || Sn^2+(aq) | Sn^3+ (aq)
O Sn(s) | Sn^2+(aq) || Sn^4+ (aq) F2 (g)|F^- (aq)| C(s)
O Sn^2+ (aq) | Sn^3+ (aq) || F2 (g)|F^- (aq)
O Pt(s) | Sn^4+ (aq), Sn2^+ (aq), F2 (g) || F^- (aq) | C(s)

Answer:

Sn^2+(aq)/Sn^3+(aq)//F2(g)/2F-(aq)

Explanation:

In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.

Given the reaction: A + B <--> C + D
Lady_Fox [76]

Answer:

A.) 4.0

Explanation:

The general equilibrium expression looks like this:

K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }

In this expression,

-----> K = equilibrium constant

-----> uppercase letters = molarity

-----> lowercase letters = balanced equation coefficients

In this case, the molarity's do not need to be raised to any numbers because the coefficients in the balanced equation are all 1. You can find the constant by plugging the given molarities into the equation and simplifying.

K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }                                       <----- Equilibrium expression

K = \frac{[2 M] [2 M]}{[1 M] [1 M] }                                     <----- Insert molarities

K = \frac{4}{1  }                                                <----- Multiply

K = 4                                                <----- Divide

why is chromatography not able to separate components of a solution which have same speed?Give reason.​
damaskus [11]

Answer:

The dyes which cover more surface area will travel more slowly. Similarly if two substances which have same speeds, they are going to travel together and they won't separate as chromatography separates substances having different rates or speeds for travelling

What creates an electric current in a battery?
kramer

Answer:

There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.

Explanation:

option (B) is right
