Can anyone help me? I don't understand the remaining formula of ions?
I figured out the following: I've bracketed molecules with *
Li+ *O2*- (Lithium Oxide)
Na+ *NO3*- (Sodium Nitrate)
K+ Cl-
*Mg*2+ Br-
*Ca*2+ I-
*Ba*2+ *CO3* 2- (Barium carbonate)
Can anyone help me with these:
-*Fe*2+
-*Fe* 3+
-*Cu*2+
-*Zn*2+
-*Al*3+
-*Ag*+
-*Pb*2+
-*NH4* +
Answer:
Fe(2+) + 2Cl(-) = FeCl2 (Ferrous chloride)
Fe(3+) + 3Br(-) = FeBr3 (Ferric bromide)
Cu(2+) + O(2-) = Cu2O (Cuprous oxide)
Zn(2+) + SO4(2-) = ZnSO4 (Zinc sulphate)
Al(3+) + 3OH(-) = Al(OH)3 (Aluminium hydroxide)
Ag(+) + NO3(-) = AgNO3 (Silver nitrate)
Pb(2+) + S(2-) = PbS (Lead(II) sulphide)
NH4(+) + Cl(-) = NH4Cl (Ammonium chloride)
i do not understand what you don´t understand.
the names of all elements are listed in the periodic table. you have had 4 answers of this type already answered.
don´t be that lazy.
