Which redox properties does H2O2 exhibit respectively, in given reactions?

$2\mathrm{Cr}(\mathrm{OH}{)}_3+4\mathrm{NaOH}+3{\mathrm{H}}_2{\mathrm{O}}_2\to 2{\mathrm{Na}}_2{\mathrm{CrO}}_4+8{\mathrm{H}}_2\mathrm{O}$

$2{\mathrm{K}}_3\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right]+2\mathrm{KOH}+{\mathrm{H}}_2{\mathrm{O}}_2\to 2{\mathrm{K}}_4\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right]+2{\mathrm{H}}_2\mathrm{O}+{\mathrm{O}}_2$
