Which pair of atoms has the most polar bond?<br> (1) H−Br <br> (2) H−Cl <br> (3) I−Br<br> (4) I−Cl
S_A_V [24]
For the question given above, option 2 which is H-Cl pair of atoms has the most polar bond among the four of them. 

The larger the value of the electronegativity, the greater the atom’s strength to attract a bonding pair of electrons. <span>Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. The electron pair that is bonding HCl together shifts toward the chlorine atom because it has a larger electronegativity value.</span>

Which statements describe the law of conservation of charge? Check all that apply.
AlekseyPX
The statements in accordance with the law of conservation of charge are:
A. The total charge of the reactants and products must be equal
B. The net charge of an isolated system remains constant

Both of these statements follow the law of conservation of charge which states that charge may neither be created nor destroyed, due to which the total charge in an isolated system (one in which charge can not move in or out of) remains constant.

Write a balanced half-reaction for the product that forms at each electrode in the aqueous electrolysis of the following salts:(
likoan [24]

Balanced Half reactions are:

At anode 2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}

At Cathode:  2H^{+} + 2e^{-} ==> H₂

Since the question states that you are using an aqueous solution of MnCl₂,  so ions will have present are, H₂O, H^{+}, Mn^{2+} and Cl^{-}

Now at Anode reaction will occur as given:

2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}  (will occur)

At Cathode:

2H^{+} + 2e^{-} ==> H₂ (will occur)

At Cathode:

Mn^{2+} +  2e^{-}==> Mn (This reaction will not occur)

The deposition of solid Mn will not occur because in aqueous solution, H^{+}will be reduced before Mn^{2+} .

The reduction potentials for H^{+} is zero whereas reduction potential for Mn^{2+} is - 1.18V.

The reduction potential of a species is its tendency to gain electrons and get reduced. It is measured in millivolts or volts. Larger positive values of reduction potential are indicative of a greater tendency to get reduced.
