Chemical Properties of Hydrogen with equations
Chemical Properties of Hydrogen: 1. Decomposition of molecular Hydrogen (H 2 ) Molecular hydrogen contains stable covalent bonding and is relatively inert at ordinary conditions. Its bond dissociation energy is 104 K.cals/mol. H — H H + H r H = 104 K.cals/mol. i.e +435 KJ/,mol. Q. Show hydrogen is a good reducing agent: 2. As a reducing Agent Hydrogen shows greater affinity for oxygen and reduces many metal oxides into free metals. CuO (s) + H 2(g) Cu (s) +3H 2 O (g) WO 3(s) + 3H 2(g) W (s) + 3H 2 O (g) 1. Hydrogenation Reaction: The addition of hydrogen into other molecular compounds called hydrogenation reaction. When molecular compounds and Hydrogen are heated in the presence of Pt or Pd or Ni and other crystals
