Answer 1

Răspuns:

1.

S + O2 => SO2

2.

ms=246g

C=20%

md= C×ms/100=20×246/100=49,2g H2SO3

MSO2 =32+2×16=64g/mol

MH2SO3=2×1+32+3×16=82g/mol

64g...........................82g

SO2 + H2O => H2SO3

xg.............................49,2g

x=49,2×64/82=38,4g SO2

MS=32g/mol

32g..............64g

S + O2 => SO2

yg...............38,4g

y=38,4×32/64=19,2g S
