Okay, sorry.
Can I post these answers and you tell me if I did anything wrong then
.Balance and identify the species that have been oxidized and the species that have been reduced.
Reaction
Cl2 + I- --> I2 + Cl-
Oxidized: I-
Reduced: Cl2
WO2 + H2 ---> W + H2O
Oxidized: 2H2
Reduced: W
Ca + H2O --> H2 + Ca(OH)2
O: Ca
R: H2
Al + O2 --> Al2O3
O: 4Al
R: 3O2
2. If the following redox reactions are found to occur spontaneously, identify the more active metal in each reaction.
For this, I was just confused at how to tell if they occur SPONTANEOUSLY....wasn't sure if they all did, so these are my answers assuming they do occur spontaneously, but could you explain to me if they don't.
2Li + Cu²+ --> 2Li+ + Cu
2Li more active
Cr + 3V³+ --> 3V²+ + Cr³+
Cr more active
Cd + 2Ti³+ --> 2Ti²+ + Cd²+
Cd more active
