Solution of task 233 of Chemistry Book Shimanovich 2003

233. Reactions are expressed by schemes:
HNO3 + Zn-N2O + Zn (NO3) 2 + H2O
FeSO4 + KClO3 + H2SO4 - Fe2 (SO4) 3 + KCl + H2O
Compose electronic equations. Arrange the coefficients in the reaction equations. For each reaction, indicate which substance is an oxidizer, which is a reducing agent; What substance is oxidized, what is recovered.
