Add 450 million grams to the solution
The element with 8 electrons in its 3d sublevel is Ni,
Nickel. The answer is letter D. The
rest of the choices do not answer the question above.
The answer is the principal quantum number
Hope this helps
The first statement is true because in a solution, the paticles settle out, and you can like no longer see them. An example of this would be when you make kool-aid becuase the particles settle out after you mix it together, and you can't seperate it either.
Answer:
NaCl in water; ion-dipole interaction
Explanation:
Sodium chloride is an ionic solid. Ionic solids dissolve in water due to ion dipole interaction. Ionic solids are composed of an ion pair which are strongly bound by electrostatic interaction between the oppositely charged ions in the solid state.
When an ionic substance is dissolved in water, the positive ion interacts with the negative end of the dipole in water while the negative ion interacts with the positive end of the dipole in water. Hence the ions are pulled apart by this ion-dipole interaction and the crystal structure of the solid collapses as the ionic solid dissolves in water.
Sodium chloride is an ionic solid. Interaction between the sodium ion and the negative end of the dipole in water as well as chloride ion and the positive end of the dipole in water leads to the dissolution of sodium chloride solid in water. This is the strongest solute-solvent interaction in the list.
