AgNO3 reacts with CoCl2 based on the following equation:
<span>AgNO3 + CoCl2 ........> CoNO3 + AgCl<span>2
</span></span>
The complete ionic equation for this reaction is:
<span>Co2+(aq) + 2Cl- (aq) + 2Ag+(aq) + 2NO3-(aq) ...> 2AgCl(s) + Co2+(aq) + 2NO3-(aq)
</span>while the net ionic equation is:
<span>Cl-(aq) + Ag+(aq) → AgCl(s)
</span>
From this ionic equations, we can see that Co2+ and NO3- remained unchanged in the ionic equations. Therefore <span>Co2+ and NO3- are the spectator ions.</span>
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion
Atoms, the building blocks of life
Answer:
Quantum Mechanical Model of Atom
The solution of the wave equation brings the idea of shells, sub-shells and orbitals. The probability of finding an electron at a point within an atom is proportional to the |ψ|2 at that point, where ψ represents the wave-function of that electron.
