Which of the following are oxidation-reduction reactions?
Fe(s) + 2AgNO3(aq) → Fe(NO3)2(aq) + 2Ag(s)
Ni(OH)2(s) + 2HCl(aq) → NiCl2(aq) + 2H2O(l)
OH−(aq) + H+(aq) → H2O(l)
2NO2(g) → N2O4(g)
Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)
I thought the answers would be
Yes
No
No
Yes
Yes
But I am way off somehow
Thank you and have a great week
