The molar solubility is the Pb ions present. PbCO3 dissociate to form Pb ions and CO3 ions
Ksp 7.40x10^-14 is equal to (Pb ions) (CO3 ions)
Pb ions correspond to CO3 ions
(pb ions)( Pb ions) is equal to 7.40x10^-14
therefore Pb ions is square root of 7.4x10^14 which is 2.27x10^-7m
In g/l is (2.27x10^-7) x 267(RFM of PbCO3) which is 6.06x10^-5 g/l
Answer:
Electrons, with a charge of -1.
Explanation:
The nucleus of the atom is composed of protons and neutrons.
The nucleus is where the bulk of the mass of an atom is found.
Electrons orbit the nucleus in various energy levels.
Protons have a charge of +1, neutrons have no charge, and electrons have a charge of -1.
The answer for this is because 98,8
A substance that donates electrons to form a covalent bond. So the answer is B
