It has been proven any intake of lead is dangerous to your health.
no
These metals are not solubles in water and doesn't react with water.
Yes, it is a chemical reaction.
The reaction is:Pb(NO3)2 + 2 NaOH = Pb(OH)2 + 2 NaNO3Lead hydroxide is insoluble in water.
Examples are silver chloride and Pb(II) chloride.
Pb(NO3)2----------Pb2+ + 2 (NO3)-
hot water helps to break the bond between pb and cl.
Cellery and PB PB & Jelly Chocolate and PB
In the Penetrant PB B'laster, the PB stands for Penetrating B'laster.
because if you were to write PB then it would be a compound not a single element while Pb is lead.
let's have two numbers a and b and a set of primes (pi) Suppose a = pa pa+1pa+2... and b = pb pb+1 pb+2... If at least one pi in both factorization is in common then the two numbers are not coprime (relatively prime), if none is in common then they are coprime
Pb is a compound.
