Question

5. When naming an anion, if it is a non-oxyanion, then it's name end with Give the name of CI 6. Name: FeO Fe203 CaCl2 Zno PbS MgBr2 like H SC 7. If an oxyanion ending with -ate, like SO?, then its acid name is ended with is named as like 8. If an oxyanion ending with -ite, like SO32, then its acid's name is ended with H2SO, is named as and end with 9. If an anion ending with -ide, then it's binary acid name start with e.g. the name of HCl is 10. The name of NO;' is , then the name of NO, is 11. How do you identify an element a metal or nonmetal? 12. How do you name a molecular compond?

Answer 1

5) end with suffix- ide. Name of Cl- is chloride.

6)FeO - ferrous oxide. Fe2O3- ferric oxide

CaCl2- calcium cloride ZnO - zinc oxide

PbS - lead sulfide. MgBr2 - magnesium bromide

Note : non oxyanion ends with suffix - ide and oxyanion ends with suffix either - ic or - ous.

7) ends with - ic so the name of H2SO4 is sulfuric acid.

8)ends with - ous. So the name of H2SO3 is sulfurous acid.

Note: more oxygen ends with- ic and fewer oxygen ends with - ous.

9) binary acid name starts with hydro and ends with - ic. So name of HCl is hydrochloric acid.

10)NO3- is nitrate and NO2- is nitrite because fewer oxygen ends with - ite and more oxygen ends with - ate.

11) there are some properties which helps to identify an element as metal or non metal like state, conductivity, malleable, ductility etc.

12) the molecular compound is named as with first element first and then second element by using the stem of element and starts with prefix and ends with suffix.
