What is the balanced equation of Zn+Pb(NO3)2---Pb+Zn(NO3)2?

Answer 1

The balanced equation is #"Zn" + "Pb"("NO"_3)_2 → "Pb" + "Zn"("NO"_3)_2#

To balance the equation, you adhere to a methodical process.

Begin with the provided equation:

#"Zn" + "Pb(NO"_3)_2 → "Pb" + "Zn(NO"_3)_2#
A method that often works is to balance everything other than #"O"# and #"H"# first, then balance #"O"#, and finally balance #"H"#.

Starting with the formula that appears to be the most complex is another helpful approach.

The most complicated formula looks like #"Pb(NO"_3)_2# or #"Zn(NO"_3)_2#.
Let's choose #"Pb(NO"_3)_2#. We put a 1 in front of it to remind ourselves that the coefficient is now fixed.

We begin with

#"Zn" + color(red)(1) "Pb(NO"_3)_2 → "Pb" + "Zn(NO"_3)_2#
Balance #"Pb"#:
We have fixed 1 #"Pb"# on the left, so we need 1 #"Pb"# on the right. We put a 1 in front of the #"Pb"#.
#"Zn" + color(red)(1) "Pb(NO"_3)_2 → color(green)(1) "Pb" + "Zn(NO"_3)_2#
Balance #"N"#:
We have fixed 2 #"N"# on the left, so we need 2 #"N"# on the right. We put a 1 in front of the #"Zn(NO"_3)_2#.
#"Zn" + color(red)(1) "Pb(NO"_3)_2 → color(green)(1) "Pb" + color(orange)(1) "Zn(NO"_3)_2#
Balance #"Zn"#:
We have fixed 1 #"Zn"# atom on the right so we need 1 #"Zn"# atom on the left. We put a 1 in front of the #"Zn"#.
#color(blue)(1)"Zn" + color(red)(1) "Pb(NO"_3)_2 → color(green)(1) "Pb" + color(orange)(1) "Zn(NO"_3)_2#

Now that each formula has a fixed coefficient, the equation ought to be balanced.

Let us verify:

#"Element"color(white)(m)"Left-hand side"color(white)(m)"Right-hand side"# #color(white)(ml)"Zn"color(white)(mmmmmll)1color(white)(mmmmmmmll)1# #color(white)(ml)"Pb"color(white)(mmmmmll)1color(white)(mmmmmmmll)1# #color(white)(ml)"N"color(white)(mmmmmml)2color(white)(mmmmmmmll)2# #color(white)(ml)"O"color(white)(mmmmmml)6color(white)(mmmmmmmll)6#

Atoms all balance. The equation that is in balance is

#color(red)("Zn" + "Pb"("NO"_3)_2 → "Pb" + "Zn"("NO"_3)_2#

The original equation was, surprise!, already balanced.

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.
