The reactants of two chemical equations are listed. equation 1: pbno3 + mg equation 2: pbno3 + ki based on the type of reaction, which reaction can be used to extract lead metal from lead nitrate solution? equation 2, because k being more reactive, exchanges position with pb in pbno3 equation 2, because k being more reactive, exchanges position with n in pbno3 equation 1, because mg being more reactive, replaces n from pbno3 equation 1, because mg being more reactive, replaces pb from pbno3

The given chemical equations are:

Equation 1.

Equation 2.

From the activity series, both Magnesium(Mg) and Potassium(K) are reactive compared to Lead(Pb). So, both of them can replace Pb from its salt lead nitrate. The first reaction is single replacement reaction, so Mg can replace Pb from lead nitrate solution giving solid lead (Pb). The second reaction is double replacement reaction, where lead reacts with iodide ion to form a precipitate of lead iodide but not solid lead.

So the correct answer would be:

Equation 1, because Mg being more reactive, replaces Pb from

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
