Pb(NO₃)₂ + (NH₄)₂CO₃ → PbCO₃ + 2 NH₄NO₃
Explanation:
Reaction of lead (II) nitrate with ammonium carbonate will produce lead (II) carbonate and ammonium nitrate.
The balanced chemical equation is:
Pb(NO₃)₂ + (NH₄)₂CO₃ → PbCO₃ + 2 NH₄NO₃
To balance the chemical equation the number of atoms of each element
entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

Answer:
1.8×10^-2mm or 0.018mm
Explanation:
Density = mass/Volume
But volume= area×thickness
Area= 50ft2= 46451.52cm2
Mass=8oz= 226.7962g
Density= 2.70g/cm3
Thickness= mass/density ×area
= 226.7962/46451.52×2.70= 1.8×10-3cm= 1.8×10^-2mm
