化學-如何証明碳和濃硫酸反應生成二氧化碳,二氧化硫和水

put carbon and H2SO4 together, some product came out.
proof:
first, put the gas of product into lime water, if it changes to milky, then it have CO2
second, dip the cobalt(II) chloride paper into the product, if it change to pink, it have water.
third, dip the wet blue litmus paper into the product, if it change to red then colourless, then it contain surphur dioxide.

if these three test can have these answers, then u can say that carbon and H2SO4 give out water, CO2 and SO2.

對於水，可以用氯化鈷試紙，如呈粉紅色者，即有水。
二氧化硫，可以用重鉻酸鉀試紙，由橙黃色試紙變成墨綠色。
CO2，可以用澄清的石灰水，如呈渾厚耆，即含CO2

6c+2h2so4=2co2+1so2+2h2o

或者6C+2H2SO4--->CO2+2SO2+2H2O
