Question

Что образуется C+F2= C+O2= C+Si= C+S= C+H2SO4= C+PbO2= C+HNO3= C+CuO= C+Fe=

Answer 1

C + 2F2 = CF4
C+O2=CO2
C+Si=SiC(Карбит кремния)
C+S=CS2 
C+H2SO4=СО2+SO2+H2O
PbO2 + C = Pb + CO2
C+HNO3=CO2+NO+H2O 
C+CuO  = Cu + CO
C + Fe = FeC( если Fe 2+)
C + 3 Fe = Fe3C( если Fe 3+)

Answer 2

C + F2 = CF2 (carbon tetrafluoride) C + O2 = CO2 (carbon dioxide) C + Si = SiC (silicon carbide) C + S = CS2 (carbon disulfide) C + H2SO4 = H2C (carbonic acid) + SO2 + H2O C + PbO2 = PbCO3 (lead carbonate) C + HNO3 = CO2 + NO2 + H2O C + CuO = CuCO3 (copper carbonate) C + Fe = FeC (iron carbide)
