Question

Anions actions Section Post-lab Assignment Complete and balance the chemical reaction can ch o o se evidence of reaction, wine NR on the products side on your bra , decide which of the elements in each pair you tested is more active. Remember that the more active of the two oxidis more readily. The total bydrogen of acts chemically by losing de similar to a metal? least one element compound clement pound more less IN A + BC = B + AC | Mg + Z/NO) → no reach Pb+ Zn(No. Pb(NO)12 8 | zn Pb Cu + Pb(NO you mix Cat AgNO, and form HC на- 2n + ends form: me of the HCI- Mg + 2. Based on your activity assignments, place the tested elements into an activity series, with the most active on the left, least active on the right lotional tests needed to complete 3. Suggest chemical equations (like those in A-G above) for any your activity series copper) Single Replacement: 5 Note: In general, single replacement reactions in aqueous solution will yield copper il) io,

Answer 1

Answer 1):-

Reactants element compound Products element 1 Activity compound more less o Mg + Zn(NO3)₂ Pb + Zn(NO3)2 Cu + Pb(NO3)2 + 2 AgNO3 Cu + ice Zn + 2Hce Mg(NO3) + Zn mg. No Reaction an It No Reaction Pb Cu(NO3)2 + 2Ag cu No Reaction Incl + H₂ Mg + 2HCl MgCl₂ + H₂ mg

Answer 2):- Reactivity series:-

(Most reactive) Mg < Zn < Pb < H < Cu < Ag (least reactive)

Answer 4):-

a) – Mg (NO3), agit – Ag(s) - b) 1 Cu(NO3), (09)+ 1 Z NOG No Reaction, ZN (NO3), (09) Z + Cu (s) 0 2 A3 NO2 (99) +14, (9) 2HNO360 + 2 Ag (6) d) 1 Pb(NO₃) (aq) + 1 Mg(s) Mg (NO₂) cag) 2 + Pb(s)

Answer 5):-

ga) reduced : ww us Au (NO) oxidised; . 4 Cuis) b) reduced. oxidised; Ni(NO₂) mg (5)
