Describe how heat is transferred from one place to another by convection.

Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids  and radiation through anything that will allow radiation to pass. The method used to transfer heat is usually the one that is the most efficient.

Answer///precipitate;

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
