1 Chapter 141 Chapter 14: Hydrogen, Oxygen, and Water 1. Hydrogen properties reactions production and uses hydrides 2. Oxygen properties reactions production and uses of oxygen oxides, peroxides anhydrides 3. Water: hydrates

2 Chapter 142 review topics: CHAPTER 4

3 Chapter 143 properties of hydrogen

4 Chapter 144 reactions of hydrogen acts like a halogen when reacting with a metal: acts like an alkali metal when reacting with a halogen: forms covalent bonds with many nonmetals and semi- metals (C, H, Si, N, P, B) production of hydrogen very pure : electrolysis of water 2H 2 O(l)  2H 2 (g)+O 2 (g) in the lab: Zn(s)+2HCl(aq)  ZnCl 2 (aq)+H 2 (g)

5 Chapter 145 production of hydrogen commercially: reduce water with Fe, C, or CH 4 the steam-hydrocarbon reforming process H 2 O(g)+CH 4 (g)  CO(g)+3H 2 (g)  H=+206 kJ CO(g)+H 2 O(g)  CO 2 (g)+H 2 (g)  H-41 kJ uses of hydrogen D 2 O: coolant for nuclear reactors O 2 &H 2 : space shuttle fuel N 2 &H 2 : fertilizer (95% of all hydrogen) CO&H 2 : methanol, CH 3 OH

6 Chapter 146 binary hydrides: compounds that contain hydrogen and one other element >ionic hydrides: compounds of H and the alkali and alkaline earth metals >covalent hydrides: compounds of H with nonmetals and semimetals like B, C, O, N, F, Cl, Br, I, P, As, S >metallic (interstitial) hydrides: MH x ; sometimes nonstoichiometric

7 Chapter 147 binary hydrides ionic hydrides covalent hydrides metallic hydrides

8 Chapter 148 metallic (interstitial hydrides): MH x ; sometimes nonstoichiometric
