Given the partial equation:
IO³⁻ (aq) + Sn²⁺ (aq) → I⁻ (aq) + Sn⁴⁺ (aq),
balance the reaction in acidic solution using the half-reaction method and fill in the coefficients.
The missing blanks represent H2O, H+, or OH-, as required to balance the reaction. Enter the coefficients as integers, using the lowest whole numbers. If the coefficient for something is "1", make sure to type that in and not leave it blank. Enter only the coefficients.
IO³⁻ (aq) + Sn²⁺ (aq) + → I⁻ (aq) + Sn⁴⁺ (aq) +

Answer : The balanced chemical equation in acidic medium will be,

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Rules for the balanced chemical equation in acidic solution are :

First we have to write into the two half-reactions.

Now balance the main atoms in the reaction.

Now balance the hydrogen and oxygen atoms on both the sides of the reaction.

If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the less number of oxygen are present.

If the hydrogen atoms are not balanced on both the sides then adding hydrogen ion at that side where the less number of hydrogen are present.

Now balance the charge.

The given chemical reaction is,

The oxidation-reduction half reaction will be :

Oxidation :

Reduction :

First balance the main element in the reaction.

Oxidation :

Reduction :

Now balance oxygen atom on both side.

Oxidation :

Reduction :

Now balance hydrogen atom on both side.

Oxidation :

Reduction :

Now balance the charge.

Oxidation :

Reduction :

The charges are not balanced on both side of the reaction. Thus, we are multiplying oxidation reaction by 2 and the adding both equation, we get the balanced redox reaction.

Oxidation :

Reduction :

The balanced chemical equation in acidic medium will be,

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
