Consider the following mechanism.
solong [7]

Answer :

(a) The overall equation is:

ClO^-(aq)+I^-(aq)\rightarrow Cl^-(aq)+IO^-(aq)

(b) The intermediates are  :

OH^-(aq),HClO(aq)\text{ and }HIO(aq)

Explanation :

<u>Part (a) :</u>

(1) ClO^-(aq)+H_2O(l)\rightarrow HClO(aq)+OH^-(aq)   (fast)

(2) I^-(aq)+HClO(aq)\rightarrow HIO(aq)+Cl^-(aq)    (slow)

(3) OH^-(aq)+HIO(aq)\rightarrow H_2O(l)+IO^-(aq)   (fast)

By adding the three equations and cancelling the common terms on both side, we will get the overall equation.

ClO^-(aq)+I^-(aq)\rightarrow Cl^-(aq)+IO^-(aq)

<u>Part (b)  :</u>

Intermediates are generated and consumed in the mechanism and do not include in the overall equation.

Since, intermediates will not include in the overall mechanism.

The intermediates are  :

OH^-(aq),HClO(aq)\text{ and }HIO(aq)

This formula equation is unbalanced.
Afina-wow [57]
The balanced equation will read:

Pb(NO3)2 (aq) + LiSO4 (aq) ➡️ PbSO4 (s) + 2️⃣LiNO3 (aq)

21. What is happening in terms of energy and attractive/repulsive forces when atoms come together and
muminat

Answer:

So A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Explanation:

words to know: covalent bond, electronegativities, and simultaneously

Covalent Bond: A chemical bond formed when electrons are shared between two atoms. Usually each atom contributes one electron to form a pair of electrons that are shared by both atoms.

Electronegativities: the degree to which an element tends to gain electrons and form negative ions in chemical reactions.

Simultaneously: at the same time.

hope this helps!

A student who was training for a cross-country race jogged for 1.0 hour and covered a distance of 1.5 kilometers. How much farth
densk [106]

Answer:

He would travel 3 kilometers.

Explanation:

Since he had already covered 1.5 kilometers in the time of 1 hour that means if he jogged for 1 more hour assuming he is going at the same pace he would've jogged 1.5 kilometers again and when you add that to the 1.5 kilometers he started with it would add up to 3 kilometers.

The pressure of a sample of dry air is held constant 2.25 atm while the temperature is
natka813 [3]
Charles’ law: V1/T1 = V2/T2. The volume and temperature of a fixed amount of gas at a constant pressure are directly proportional. To use the equation, the temperature must be in Kelvin.

V2 = V1T2/T1 = (43 L)(280.15 K)/(373.15 K)
V2 = 32 L

The correct answer choice would thus be B.
