Answer 2

1) Magnesium nitride
Mg3N2
2) Calcum Oxide
CaO
3) silver fluoride
AgF
4)beryllium chloride
BeCl2
5)potassium iodide
KI

Answer 3

) magnesium nitride

2) calcium oxide- CaO

3) silver fluoride- AgFl

4) beryllium chloride

5) potassium iodide-KI
I can't remember the valences forthe Nitride or Beryllium

Answer 4

When the chemical formula is ionic (metal with non-metal) you don't use prefixes such as mono, di, tri etc. When it is covalent you do use prefixes. First determine the charge on the cation and anion. Cl has a 1- charge so Cu has to balance that charge. Cu has a variable charge of 1+ and 2+ so you would balance Cl with Copper 1 to get Copper(1)Chloride CLO is hypochlorate. This is found in your polyatomic ion table from your teacher or in your textbook. So the answer is Calcium Hypochlorate

Answer 5

1. Mg3N2
2. CaO
3. AgF
4. I couldn't find Beryllium but Chloride has a charge of Cl-
5. KI

Answer 6

1) Mg2+ + N3- → Mg3N2
2)Ca2+ + O2- → CaO
3)Ag+ + F- → AgF
4)Be2+ + Cl- → BeCl2
5)K+ + I- → KI

Note that this is just the stoichiometry way of putting it together with the charges of the species that you want to know. Also, the add signs are kind of close together, so I hope this doesn't confuse you.

Answer 7

1. Mg3N2
2. CaO
3. AgF
4. BeCl2
5. KI

-- use the charges of the cations and anions -- that might help
