write the formulas for the following compounds

Question

Sodium chlorate i put NaCl
Lead (II) phosphate i put Pb2P
For Magnesium hydrogen carbonate i had no clue!
then it stats state the number of electrons lost or gained in forming each of these Ions. I didn't understand the question but they were
Mg2+
Ca2+
Br- and Ag+
then it says name each ions in the question and tell whether they are anions or cataions
for Mg2+ i put cation
for Ca2+ i put cation
for Br- i put anion
and for Ag+ i put cation

thanks in advance

Answer 1

most of them are true... except for question with polyatomic ion

Sodium chlorate = NaClO3 (chlorate is a polyatomic ion)
Lead(II) phosphate = Pb3(PO4)2
Magnesium hydrogencarbonate =Mg(HCO3)2
*** you need to review your polyatomic ion)

Answer 2

sodium chlorate: NaClO3
lead II phosphate: Pb3(PO4)2

Magnesium => Mg
Hydrogen carbonate=> HCO3

since in group 2 (Mg)

then Mg(HCO3)2

Answer 3

ok but what about the rest of the questions?

Answer 4

then it stats state the number of electrons lost or gained in forming each of these Ions. I didn't understand the question but they were
Mg2+ so since it's 2+ then it has lost 2 electrons
Ca2+ 2 as well
Br-gained 1 e- and Ag+ since it's + then it obviously lost 1 e-
then it says name each ions in the question and tell whether they are anions or cataions
for Mg2+ i put cation
for Ca2+ i put cation
for Br- i put anion
and for Ag+ i put cation
all these are okay
