write the chemical formula for each of the given names. 6. aluminum chloride 7. zinc oxide 8. barium bromide…

Answer:

6. $\text{AlCl}_3$
7. $\text{ZnO}$
8. $\text{BaBr}_2$
9. $\text{Li}_3\text{N}$
10. $\text{K}_2\text{S}$

Explanation:

Step1: Determine aluminum ion and chloride ion

Aluminum forms $\text{Al}^{3 + }$ and chlorine forms $\text{Cl}^{-}$. To balance charges, 3 chloride ions are needed, so formula is $\text{AlCl}_3$.

Step2: Determine zinc ion and oxide ion

Zinc forms $\text{Zn}^{2+}$ and oxygen forms $\text{O}^{2 - }$. Charge - balance gives $\text{ZnO}$.

Step3: Determine barium ion and bromide ion

Barium forms $\text{Ba}^{2+}$ and bromine forms $\text{Br}^{-}$. Two bromide ions are needed for charge - balance, so formula is $\text{BaBr}_2$.

Step4: Determine lithium ion and nitride ion

Lithium forms $\text{Li}^+$ and nitrogen forms $\text{N}^{3 - }$. Three lithium ions are needed for charge - balance, so formula is $\text{Li}_3\text{N}$.

Step5: Determine potassium ion and sulfide ion

Potassium forms $\text{K}^+$ and sulfur forms $\text{S}^{2 - }$. Two potassium ions are needed for charge - balance, so formula is $\text{K}_2\text{S}$.
