Answer:
the answer is ClF3 on edge
Explanation:
atomic number = protons.
protons+neutrons=atomic mass.
170 (mass) - 41 (proton/number) = 129
that should be ur answer. I hope this helps!
When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions.
Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.
