Answer 2

Chemical Formulas of Compounds

Here are the chemical formulas for the compounds based on the given valencies:

1. Magnesium Nitride (MgN): - Magnesium (Mg) has a valency of 2. - Nitrogen (N) has a valency of 3. - To balance the charges, we need two magnesium ions and three nitride ions. - Therefore, the chemical formula for magnesium nitride is Mg3N2.

2. Phosphorus Oxide (P2O): - Phosphorus (P) has a valency of 2. - Oxygen (O) has a valency of 2. - To balance the charges, we need two phosphorus ions and one oxide ion. - Therefore, the chemical formula for phosphorus oxide is P2O.

3. Iron(I) Chloride (FeCl): - Iron (Fe) has a valency of 1. - Chlorine (Cl) has a valency of 1. - To balance the charges, we need one iron ion and one chloride ion. - Therefore, the chemical formula for iron(I) chloride is FeCl.

4. Sulfur Tetraoxide (SO4): - Sulfur (S) has a valency of 4. - Oxygen (O) has a valency of 2. - To balance the charges, we need one sulfur ion and four oxide ions. - Therefore, the chemical formula for sulfur tetraoxide is SO4.

Please note that the valencies provided in the question are not entirely accurate. The valencies used in the chemical formulas are based on common valencies for the elements mentioned.
