Aqueous solutions of ammonium chloride and lead nitrate produce leadon chloride precipitate and aqueous ammonium nitrate. What type of reaction is this? How do you balance the equation?

Answer 1

See the explanation.

#"2NH"_4"Cl(aq)"+"Pb(NO"_3)_2"(aq)"##rarr##"2NH"_4"NO"_3"(aq)"+"PbCl"_2"(s)"#

This is a double replacement reaction, where one of the products is a precipitate, which is also referred to as a double displacement, metathesis, or precipitation reaction.

The general equation is #"AX"+"BY"##rarr##"AY"+"BX"#, where A and B are cations and X and Y are anions.

The balanced equation for this double displacement reaction is as follows: 2NH4Cl(aq) + Pb(NO3)2(aq) → PbCl2(s) + 2NH4NO3(aq)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
