Can someone tell me if I am getting these correct?

Give formula for the following covalent compounds:
1. Sulfur hexafluoride-SF6
2. Tetraphosphorus heptasulfide-P4S7
3. Silicon tetrachloride-SiCl4
4.Disulfur decafluroine moniodide-S2F10I
5. Iodine pentafluoride-IF5
6. Tetranitrogen trisulfide-N4S4
7. Diarsenic trisulfide-As2S3

All look ok except for #6. I think that is N4S3

Sure! I can help you verify if you have correctly written the formulas for the given covalent compounds. Let's go through each compound one by one.

1. Sulfur hexafluoride - SF6
This compound consists of one sulfur atom (S) and six fluorine atoms (F). To determine the formula, you need to balance the charges of the atoms. Since sulfur has a valence of 2 and fluorine has a valence of 1, you'll need six fluorine atoms to balance the charge of one sulfur atom. Therefore, the formula is correct: SF6.

2. Tetraphosphorus heptasulfide - P4S7
In this compound, you have four phosphorus atoms (P) and seven sulfur atoms (S). Similarly, you need to balance the charges. Since phosphorus has a valence of 5 and sulfur has a valence of 2, you'll need seven sulfur atoms to balance the charges of four phosphorus atoms. Thus, the formula is correct: P4S7.

3. Silicon tetrachloride - SiCl4
This compound contains one silicon atom (Si) and four chlorine atoms (Cl). Following the same process as before, you need four chlorine atoms to balance the charge of one silicon atom. So, the formula is correct: SiCl4.

4. Disulfur decafluorine moniodide - S2F10I
In this compound, you have two sulfur atoms (S), ten fluorine atoms (F), and one iodine atom (I). Similarly, you must balance the charges. Since sulfur has a valence of 2, fluorine has a valence of 1, and iodine has a valence of 1, the formula is already balanced. Therefore, the formula is correct: S2F10I.

5. Iodine pentafluoride - IF5
This compound consists of one iodine atom (I) and five fluorine atoms (F). Following the same process as before, you need five fluorine atoms to balance the charge of one iodine atom. Thus, the formula is correct: IF5.

6. Tetranitrogen trisulfide - N4S4
In this compound, you have four nitrogen atoms (N) and four sulfur atoms (S). Using the same balancing method, you need four sulfur atoms to balance the charge of four nitrogen atoms. Hence, the formula is correct: N4S4.

7. Diarsenic trisulfide - As2S3
This compound contains two arsenic atoms (As) and three sulfur atoms (S). By balancing the charges, you need three sulfur atoms to balance the charge of two arsenic atoms. Therefore, the formula is correct: As2S3.

Overall, it appears that you have correctly provided the formulas for all the given covalent compounds. Well done!
