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

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
