4) MgBr2 magnesium bromide. Convert grams Li2S to moles or moles Li2S to grams. Summary: More Practice With Naming 1. K3Pc. 3) Li2S lithium sulfide. Metals do not form covalent compounds, so we generally don't use prefixes for compounds containing metals. 5) Be(OH)2 beryllium hydroxide Write the formulas for the following ionic compounds: 6) potassium iodide KI. 7) magnesium oxide MgO. 8) aluminum chloride AlCl3 Note that none of the above compounds contain a metal. ›› Li2S molecular weight. In air, it easily hydrolyses to release hydrogen sulfide (rotten egg odor). Following the conventions outlined above, the chemical name would be "Lithium sulfide". Alfa Aesar 12839: DANGER: Water reactive, flammable, burns skin and eyes Alfa Aesar 12839 4) In which of the following are ionic bonds important: Br2, HBr, NaBr? Name the following ionic compounds: 1) NaBr sodium bromide. Name the following: a. NaOH b. Li 2 S c. FeCl 3 (430 only) d. H 2 O e. K 3 N f. CaSO 4 2. 2) CaO calcium oxide. Al2O3 has two atoms of Aluminum and three of Oxygen. Naming Chemical Compounds Worksheet Name the following ionic compounds. a) MgBr2 b) Li2S c) Al2O3 d) Fe2O3 e) CuCl2 f) NaF. 7) magnesium oxide MgO. MgOf. 3) Li2S lithium sulfide. 4) MgBr2 magnesium bromide. 8) aluminum chloride AlCl3 NaBr 2) cao Li2S Write the formulas for the following ionic compounds: 2) CaO calcium oxide. The name of this compound would therefore be "Aluminum oxide". a) strontium bromide b) aluminum fluoride c) copper (II) iodide d) iron (III) sulfide. Molecular weight calculation: 6.941*2 + 32.065 ›› Percent composition by element Molar mass of Li2S = 45.947 g/mol. SrBr2. Thus the difference is 1.5 and that makes it polar covalent. 11-14-31-36/37/38 Alfa Aesar 12839: 26-30-37 Alfa Aesar 12839: DANGER: FLAMMABLE, WATER REACTIVE, irritates skin & eyes. 3) Give formulas for the following binary ionic compounds. 2) Name the following binary ionic compounds. ///// ditto, ditto Naming Chemical Compounds - Answers. This compound is also known as Lithium Sulfide. Lithium sulfide is the inorganic compound with the formula Li 2 S. It crystallizes in the antifluorite motif, described as the salt (Li +) 2 S 2−. Write formulae for the following: Answer to Write the name for each of the following ionic compounds:a. MgCl2b. Li2S is a polar covalent compound because the electronegitvity of Li is 1.00 and of S is 2.5. Name the following ionic compounds: 1) NaBr sodium bromide.
