In the following reaction, which component acts as an oxidizing agent? 10 I− (aq) + 2 MnO4− (aq) + 16 H+ (aq) → 5 I2 (s) + 2 Mn2

antiseptic1488 [7]

Answer:

The oxidizing agent is the MnO₄⁻

Explanation:

This is the redox reaction:

10 I⁻ (aq) + 2 MnO₄⁻ (aq) + 16 H⁺ (aq) → 5 I₂ (s) + 2 Mn²⁺ (aq) + 8 H2O (l)

Let's determine the oxidation and the reduction.

I⁻ acts with -1 in oxidation state and changes to 0, at I₂.

All elements in ground state has 0 as oxidation state.

As the oxidation state has increased, this is the oxidation, so the iodide is the reducing agent.

In the permanganate (MnO₄⁻), Mn acts with +7 in oxidation state and decreased to Mn²⁺. As the oxidation state is lower, we talk about the reduction. Therefore, the permanganate is the oxidizing agent because it oxidizes iodide to iodine

1. Which sample contains a total of 9.0 * 10 ^ 23 atoms ? A) 0.50 mole of HCI B) 0.75 mole of H 2 O C) 1.5 moles of Cu D) 1.5 mo

Alchen [17]

c. 1.5 moles of Cu will contain a total of 9.0 * 10 ^ 23 atoms.

Explanation:

To convert moles into atoms, the molar amount and number of atom is multiplied by Avagadro's number.

Avagadro's number is 6.022× $10^{23}$

So applying the formula in the given sample:

A) 0.5×6.022× $10^{23}$

3.01× $10^{23}$ atoms.

B) 0.75 mole of H20

O.75×6.022× $10^{23}$

= 4.5166× $10^{23}$ atoms.

C) 1.5 moles of Cu

1.5×6.022× $10^{23}$

= 9.033× $10^{23}$

D). 1.5 moles of H2

1.5 × 2 × 6.022 × $10^{23}$

= 18.066 × $10^{23}$ atoms because H2 is 2 moles of hydrogen.

Atom is the smallest entity of matter having property of the element to which it is a part.
