Answer: The force of attraction present between the solids depends on the type of solid.
Explanation:
For e.g. if solid is ionic solid, then the ionic forces hold on the solid molecules. And these forces hold together and form solid. When it comes to hydrogen bonding stronger the hydrogen bonding, more together the molecules and it become solid.
Answer:
Pb(NO₃)₂ (aq) + 2NaCl (aq) → PbCl₂ (s) ↓ + 2NaNO₃ (aq)
Explanation:
The reactants are:
Lead(II) nitrate → Pb(NO₃)₂ (aq)
Sodium chloride → NaCl (aq)
The products are:
Lead(II) chloride → PbCl₂ (s)
Sodium nitrate → NaNO₃ (aq)
Salts form nitrate are soluble. The chloride makes a precipitate with the Pb²⁺. The chemical equation for this reaction is:
Pb(NO₃)₂ (aq) + 2NaCl (aq) → PbCl₂ (s) ↓ + 2NaNO₃ (aq)
