Question

Balance and evaluate the following equation: AgNO3 (aq) + PbBr2 (s) yields AgBr (s) + Pb(NO3)2 (aq)

Answer 1

The balance equation is given as:

`2AgNO_3 (aq) + PbBr_2 (s) \rightarrow 2AgBr (s) + Pb(NO_3)_2 (aq)`

Step-by-step explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The balance equation is given as:

`2AgNO_3 (aq) + PbBr_2 (s) \rightarrow 2AgBr (s) + Pb(NO_3)_2 (aq)`

According to reaction,2 moles of silver nitrate react with 1 mole of lead (II) bromide to give 2 moles of silver bromide and 2 moles of lead nitrate.

When aqueous silver nitrate reacts with solid lead(II) bromide it gives solid precipitate of silver bromide and aqueous solution of lead(II) nitrate.

Answer 2

Balance the bromine (Br) in the equation by multiplying AgBr by 2. Further, multiply AgNO3 by 2 in order to balance NO3 in the equation. With this, the elements in each side become balance. This gives an answer of,
2AgNO3 (aq) + PbBr2 (s) ---> 2AgBr (s) + Pb(NO3)2 (aq)
