Chemistry 2 Chapter 9 Worksheet Key 1. Determine the oxidation number for the atoms of each element in the following formulas. a. Pa b. PF, C. PHI d. P₂O₂ e. H₂PO₂ P P P H H Ni N F H O P f. HPO 8. NISO h. N₂O i. Mn(PO₂)2 Mn 2. For each of the following equations, write the oxidation number for each atom above its symbol in the equation, and indicate whether the reaction is a redox reaction. If the reaction is redox, identify what is oxidized, what is reduced, the oxidizing agent, and the reducing agent. a. 2HNO3(aq) + 3H₂S(aq) → 2NO(g) + 3S(s) + 4H₂O() P O S O b. 2AgzCrO4(s) + 4HNO3(aq) →4AgNO3(aq) + H₂Cr₂O72(aq) + H₂O(l) c. 2MnO4 (aq) + 3103 (aq) + H₂O(l) → 2MnO₂ (s) + 3104 (aq) + 2OH(aq) 4. Classify each of these reactions with respect to the following categories: combination reaction, decomposition reaction, combustion reaction, and single-displacement reaction. W(s) + 3H₂O() A a. 3H2(g) WO(s) → b. 21409(5) →21:0(s) + 2l(s) + 302(g) A 2NaNO3(s) → 2NaNO₂(s) + O2(g) c. d. (g) + 2KBr(aq) →→2KCl(aq) + Bra() 5. Write a balanced equation for the complete combustion of C₂H5O₂H(/). Chemistry 2 Chapter 9 Worksheet Key 1. Determine the oxidation number for the atoms of each element in the following formulas. a.
