Bài 1:

a) $S+O_2\buildrel{{t^o}}\over\longrightarrow SO_2$

    $2SO_2+O_2\rightleftharpoons 2SO_3$ $(t^o,V_2O_5)$

    $SO_3+H_2O→H_2SO_4$

    $Fe+H_2SO_4→FeSO_4+H_2↑$

    $CuO+H_2\buildrel{{t^o}}\over\longrightarrow Cu+H_2O$

b) 

$Li_2O$: Liti oxit

$Fe(NO_3)_3$: Sắt $(III)$ nitrat

$Pb(OH)_2$: Chì $(II)$ hiđroxit

$Na_2S$: Natri sunfua.

$Al(OH)_3$: Nhôm hiđroxit

$P_2O_5$: Đi photpho penta oxit 

$HBr$: Axit bromhiđric

$H_2SO_4$: Axit sunfuric

$Fe_2(SO_4)_3$: Sắt $(III)$ sunfat.

$CaO$: Canxi oxit

Bài 1:

a, 

1. S + O2 -t-> SO2

2. SO2 + 2O2 -t-> 2SO3

3. SO3 + H2O -> H2SO4

4. H2SO4 + Zn -> ZnSO4 + H2

5. CuSO4 + H2 -> Cu + H2SO4

b, 

- Axit:

+ HBr: axit bromhiđric

+ H2SO4: axit sunfuric 

- Oxit

+ Li2O: Liti oxit

+ CaO: canxi oxit 

+ P2O5: điphotpho pentaoxit

- Bazo:

+ Pb(OH)2: Chì hiđroxit
