Determine the oxidation number of the underlined element.NI(CIO3)2 H3PO4 – SnCl2 Mg(OH)2 Ni(ClO3)2

For each of the following reactions, assign oxidation numbers to each atom/ion and indicate whether the equation represents a redox reaction. If it does, identify the oxidation and reduction components. a) Cu (s) + 2 AgNO3 (aq) → 2 Ag (s) + Cu(NO3)2 (aq) b) 2 NaCl (l) → 2 Na (l) + Cl2 (g) c) 2 C4H10 (g) + 13 O2 (g) → 8 CO2 (g) + 10 H2O (l) d) 2 H2O2 (l) → 2 H2O (l) + O2 (g)

How many electrons are transferred in the following reaction? (The reaction is unbalanced.) Mg(s) + Al3+(aq)→Al(s) + Mg2+(aq)

1. For the following oxidation-reduction reactions, identify the half-reactions and label them as oxidation or reduction: (a) Cu(s) + Ni²+(aq) → Ni(s) + Cu²+(aq) (b) 2 Fe3+(aq) + 3 Ba(s) → 3 Ba²+ (aq) + 2 Fe(s)
