Question

30 de puncte+ coroana plsss

Answer 1

ms=160g

a) S + O2 ---> SO2

32gS...........................32g O2

160gS...........................x

X=160×32/32=160 g O2

MO2 = 16x2=32g/mol

MS=32g/mol

b)

MSO2=32+16×2=32+32=64g/mol

32gS......................64gSO2

160gS......................x gSO2

X=160×64/32=5×64=320g SO2

c) SO2+H2O ---> H2SO3

MH2SO3= 2x1+32+16×3=82g/mol

64gSO2..........82gH2SO3

320gSO2............x

X=320×82/64=410g H2SO3

c=md×100/ms=> ms=md×100/c=410×100/10=4100g H2SO3
