A- O2
B-NAOH
C-H2
D-NABR
REAKCJE
1 2NA+BR2=2NABR
2 4NA +O2 = 2NA2O
3 2NA +2H2O --> 2NAOH + H2
4 NA2O+2H2O-----> 2NAOH+H2O
5 O2 +2H2 ---->2H2O
A-->tlen [O2]
B-->wodorotlenek sodu [NaOH]
C-->wodór [H2]
D-->bromek sodu [NaBr]
1. 2Na+Br2-->2NaBr
2. 4Na+O2-->2Na2O
3. 2Na+2H2O-->2NaOH+H2
4. Na2O+H2O-->2NaOH
5. 2H2+O2-->2H2O
