Question

1.данные превращения CH4----CO2-----K2CO3 соответствуют общей схеме : А. ЭH4------ЭO2-----H2ЭO3 Б. Э------ЭO2-----H2ЭO2 B. Э------ЭО2-----Na2ЭО3 Г. ЭН4-----ЭО2----К2ЭО3

Answer 1

ЭН4-----ЭО2----К2ЭО3

Answer 2

Chemical Reaction and Equation

The given chemical transformation is CH4 → CO2 → K2CO3. It corresponds to the general scheme: **A. CH4 → O2 → H2O3 B. C → O2 → H2O2 C. C → O2 → Na2CO3 D. NH4 → O2 → K2CO3**

The correct answer is D. The transformation of CH4 to CO2 and then to K2CO3 corresponds to the general scheme of NH4 → O2 → K2CO3.
