2CH3-CH2-CH2-CH3 + 5O2 => 4CH3COOH + 2H2O
CH3COOH + CH3OH => CH3COOCH3 + H2O
CH3COOCH3 + NaOH => CH3COONa + H2O
CH3COONa + H2SO4 => CH3COOH + NaHSO4
Ответ:
Объяснение:
Mr(Al2(SO3)3) = 27*2 + 32*3 + 16*9 =294
W(Al) = Ar(Al) *n / Mr(Al2(SO3)3) *100% = 27*2 / 294 *100% =18%
W(S) = Ar(S) *n / Mr(Al2(SO3)3) *100% = 32*3 / 294 *100% =33%
W(O) = Ar(O) *n / Mr(Al2(SO3)3) *100% = 16*9 / 294 *100% =49%
