Web17 jun. 2024 · Answer: 0.76 mole of Fe2S3. Explanation: Step 1: Determination of the number of mole in 449g iron (III)bromide, FeBr3. This is illustrated below: Mass of FeBr3 = 449g Molar mass of FeBr3 = 56 + (80x3) = 296g/mol Mole of FeBr3 =..? Mole = Mass /Molar Mass Mole of FeBr3 = 449/296 Mole of FeBr3 = 1.52 moles Step 2: WebA covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
