Question
Transcribed Image Text:I) Do the same as in the previous question (also see the NOTE).
Fe(s) +
Cu2*(aq)
Fe3+(aq) +
Cu(s)
(Place ONLY #s in the spaces when balancing)
OA =
; RA =
II) Give the oxidation number (ON) of S in the following:
a) SOCI2 : ON =
b) H2S2: ON =
c) H2SO4: ON =
d) Na2s: ON =
Transcribed Image Text:Balance each equation then identify the oxidizing agent (OA), the reducing agent (RA), the species oxidized and the species reduced:
{ NOTE:
i)
Put only numbers in the spaces to balance the equations even if it is the number "1".
ii)
For the OA, RA, species oxidized and species reduced, write the complete formula of the substance WITHOUT THE PHASE. (e.g., if H in HCI gets reduced then the OA should be written as
HCI; if the P in P4 gets oxidized then the RA should be written as P4.
iii) Do NOT use subscripts or superscripts in formula answers. Put numbers on same level as symbols (e.g. "N2" would be written as N2 in answer.)}
a)
Sg(s) +
F2(9)
SF4(9)
Species oxidized =
