write the formula for the following chemical compounds
1.Sodium sulfide
2.sulfur hexaflouride
3.Ammonium sulfate
Na2S
2. You should be able to figure it out from the name.
(NH4)2SO4.
To write the formula for chemical compounds, you need to know the symbols and charges of the individual elements or ions involved. Here are the formulas for the compounds you mentioned:
1. Sodium sulfide (Na2S):
- Sodium is represented by the symbol Na and has a charge of +1.
- Sulfur is represented by the symbol S and has a charge of -2.
To balance the charges, you need two sodium ions (Na+) and one sulfide ion (S2-). Therefore, the formula is Na2S.
2. Sulfur hexafluoride (SF6):
- Sulfur is represented by the symbol S.
- Fluorine is represented by the symbol F and has a charge of -1.
To determine the number of fluorine atoms, you need to know that the total charge of the compound is zero. Since sulfur's charge is not given, we can assume it's in its neutral state (0 charge).
To give sulfur a charge of 0 with six negatively charged fluoride ions (-1 each), we need six fluorine atoms. Therefore, the formula is SF6.
3. Ammonium sulfate (NH4)2SO4:
- Ammonium is represented by the symbol NH4 and has a charge of +1.
- Sulfur is represented by the symbol S and has a charge of +6.
- Oxygen is represented by the symbol O and has a charge of -2.
To balance the charges, you need two ammonium ions (NH4+) and one sulfate ion (SO42-). Therefore, the formula is (NH4)2SO4.
