Question

give formulas for the following binary covalent compounds: 5. tetrasulfur decafluoride sf10 6. chlorine triiodide cli3 7. dinitrogen pentasulfide n2s5 8. silicon tetrahydride sih4

Explanation:

Step1: Interpret prefixes for atoms

Prefix "tetra -" means 4, "deca -" means 10, "tri -" means 3, "penta -" means 5.

Step2: Write chemical formulas

For tetrasulfur decafluoride, sulfur is S and fluorine is F, so the formula is $S_4F_{10}$. For chlorine triiodide, chlorine is Cl and iodine is I, so the formula is $ClI_3$. For dinitrogen pentasulfide, nitrogen is N and sulfur is S, so the formula is $N_2S_5$. For silicon tetrahydride, silicon is Si and hydrogen is H, so the formula is $SiH_4$.

Answer:

1. $S_4F_{10}$
2. $ClI_3$
3. $N_2S_5$
4. $SiH_4$
