Determine whether a solid forms when solutions containing the following salts are mixed. if so, write the ionic equation and the net ionic equation.
agno3(aq) and k2s(aq)
can someone explain to me how they're getting this?

When these two compounds are mixed in a solution, a substitution reaction will take place in which the potassium ion will replace the silver ion and form potassium nitrate and silver sulfide will be formed. Silver sulfide is insoluble in water, so it will form a solid.

Ionic equation:
2Ag₊ + 2NO₃₋ + 2K₊ + S⁻² → Ag₂S + 2KNO₃

No table found. the question asks for covalent bond based on electronegativies
