You're on a roll — here's an explanation of the chemical bonds in each substance: i) H_2S (Hydrogen Sulfide) Bond type: Covalent bond* Reason: Hydrogen (H) and Sulfur (S) are both non-metals. They form bonds by sharing electrons* to achieve stable electron configurations. ii) Cu (Copper) Bond type: Metallic bond* Reason: Copper is a metal. In metallic substances, the valence electrons are delocalized* and form a "sea" of electrons shared among a lattice of positively charged copper ions. iii) NH_4Cl (Ammonium Chloride) Bond types: Ionic bond and Covalent bond* (including dative/coordinate covalent bond) Reason: An ionic bond exists between the ammonium ion (NH_4^+) and the chloride ion (Cl^-). This is due to the electrostatic attraction* between the positively charged polyatomic ion and the negatively charged anion. Covalent bonds exist within the ammonium ion (NH_4^+) itself, where nitrogen and hydrogen atoms share electrons. One of these N-H bonds is formed by a dative covalent bond* where nitrogen donates both electrons to form a bond with H^+. iv) C_2H_6 (Ethane) Bond type: Covalent bond* Reason: Carbon (C) and Hydrogen (H) are both non-metals. They form bonds by sharing electrons* to achieve stable electron configurations, both between carbon atoms (C-C) and between carbon and hydrogen atoms (C-H). What's next? Send 'em.
