浓硫酸和木炭粉在加热条件下发生的化学反应方程式

Answer 1

C+2H2SO4(浓)==加热CO2(气)+2SO2(气)+2H2O
反应到了后面,流配变稀以后就没得反应了,所以欲使C完全反应,就加入过量的H2SO4(浓),或不断往里加入2H2SO(浓).
--------------------------------------------------------------------------------
C+浓H2SO4=2H2O+SO2+CO2
--------------------------------------------------------------------------------
C+2H2SO4(浓)=(加热)=CO2↑+2SO2↑+2H2O
--------------------------------------------------------------------------------
C＋2H 2 SO 4 （浓）=CO 2 ↑＋2SO 2 ↑＋2H 2 O，等号上面是加热
--------------------------------------------------------------------------------
C+2H2SO4=CO2++2SO2+2H2O
--------------------------------------------------------------------------------

C+2H2SO4=CO2+2SO2+2H2O
--------------------------------------------------------------------------------
C+2H2SO4=====加热====2H2O+2SO2+CO2注意生成的气体上标上箭头
--------------------------------------------------------------------------------
C+H2SO4===CO2+SO2+H2O
--------------------------------------------------------------------------------
C+2H2SO4====CO2↑+2SO2↑+2H2O
--------------------------------------------------------------------------------
2H2SO4(浓+C=CO2+2H2O+2SO2反应条件是加热，CO2、SO2是气体，要有向上箭头。
