When Sodium chloride or table salt is a compound formed
when sodium loses its valence electron to chlorine, the type of bond formation
that takes place in sodium chloride is the Lewis Bond.
Answer:
is cool is cool goodcripopo
The type of energy which is present between the repulsion interaction is the highest potential energy.
<h3>What is potential energy?</h3>
Potential energy is the amount of energy that is possess by any body with respect to the electric charge posses in that and other factors also.
- When molecules have a high attraction force then they have the low potential energy in them.
- When molecules have a great repulsion between them then they have the great potential energy in them.
- And molecules have the middle amount of potential energy then they have the balanced interaction.
Hence, molecules in which repulsion interaction is present will have highest potential energy.

Answer:
The product is Methyl cyanoacetate
Explanation: see structure attached
Answer:
The precipitate is CuS.
Sulfide will precipitate at [S2-]= 3.61*10^-35 M
Explanation:
<u>Step 1: </u>Data given
The solution contains 0.036 M Cu2+ and 0.044 M Fe2+
Ksp (CuS) = 1.3 × 10-36
Ksp (FeS) = 6.3 × 10-18
Step 2: Calculate precipitate
CuS → Cu^2+ + S^2- Ksp= 1.3*10^-36
FeS → Fe^2+ + S^2- Ksp= 6.3*10^-18
Calculate the minimum of amount needed to form precipitates:
Q=Ksp
<u>For copper</u> we have: Ksp=[Cu2+]*[S2-]
Ksp (CuS) = 1.3*10^-36 = 0.036M *[S2-]
[S2-]= 3.61*10^-35 M
<u>For Iron</u> we have: Ksp=[Fe2+]*[S2-]
Ksp(FeS) = 6.3*10^-18 = 0.044M*[S2-]
[S2-]= 1.43*10^-16 M
CuS will form precipitates before FeS., because only 3.61*10^-35 M Sulfur Ions are needed for CuS. For FeS we need 1.43*10^-16 M Sulfur Ions which is much larger.
The precipitate is CuS.
Sulfide will precipitate at [S2-]= 3.61*10^-35 M
