When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS
An isotope only differs in the number of neutrons it has. All isotopes of an element <span>have the </span>same<span> atomic number (the number of electrons/protons), therefore, they have the </span>same<span> number of electrons/protons and therefore similiar chemical properties.</span>
Any element in the period of alkile earth metal cuz O has a valence electron of 6 and the alkile earth metals have V.E. of 2 which completes the octet rule...making it covalently bond to form a 2 atom molecule ex: Lewis structure Be:O
I would say #3 I’m sorry if it’s wrong tho
Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
