The Organisms that formed them likely lived during the Paleozoic era.
Pb(NO₃)₂(aq) + 2NaI(aq) → 2NaNO₃(aq) + PbI₂(s)
PbI₂ (the precipitate)
Copper (Cu) and silver (Ag) would not liberate hydrogen because they are less reactive than hydrogen since their standard reduction potential is higher.
SORRY BUT ITS BLUR:) HUHU
Answer:
Atoms are composed of electrically charged particles and moving electric charges possess an associated magnetic field.
Explanation:
An atom is made up of electrons arranged in shells. Electrons are negatively charged. These charged particles produce an electric field which can interact with an external electric field to give information about atomic structure.
Similarly, a moving electron produces an associated magnetic field which can couple with an external magnetic field to give information about atomic structure.
