(a) Determine if one or both of the following reactions can be classified as a redox (oxidation-reduction) reaction. In the case of a redox reaction, identify the species that loses electrons and the species that gains electrons. (Omit states-of-matter from your answer. Enter NONE in any unused answer blanks.)

(i)    Pd(NO3)3(aq) + Co(s) → Co(NO3)3(aq) + Pd(s)

This is a redox reaction? This is not a redox reaction?

What loses electrons? What gains electrons?

(ii)    NiSO4(aq) + NH4OH(aq) → Ni(OH)2(s) + (NH4)2SO4(aq)

This is a redox reaction? This is not a redox reaction?

What loses electrons? What gains electrons?

(b) Balance any of the above equations that are not balanced. (Write the complete molecular equation. Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

(i)    Pd(NO3)3(aq) + Co(s) → Co(NO3)3(aq) + Pd(s)

(ii)    NiSO4(aq) + NH4OH(aq) → Ni(OH)2(s) + (NH4)2SO4(aq)

(c) What type of reaction?

(i)    Pd(NO3)3(aq) + Co(s) → Co(NO3)3(aq) + Pd(s)

This is a single-displacement reaction? This is a double-displacement reaction? This is not a displacement reaction?

(ii)    NiSO4(aq) + NH4OH(aq) → Ni(OH)2(s) + (NH4)2SO4(aq)

This is a single-displacement reaction? This is a double-displacement reaction? This is not a displacement reaction?
