## Question
I don't know if $\\ce{C}$ or $\\ce{CuO}$ react with $\\ce{H2SO4}$. Some sources say that: $$\\ce{C + H2SO4 -> CO2 ^ + 2SO2 ^ + 2 H2O}$$ (It seems to be similar to $\\ce{Cu}$ reactions with $\\ce{H2SO4}$). Is the reaction possible? If the answer is yes, in what conditions does the reaction take place?
And I was pretty sure that $\\ce{CuO + H2SO4 -> CuSO4 v + H2O}$
But my chemistry book says that none of the reactions is possible. I'm little bit confused, some help would be apreciated.

Carbon reacts with sulfuric acid to produce carbon dioxide and sulfur dioxide gas along with water. Sulfuric acid should be a concentrated, heated solution.
$$\\ce{C + 2H2SO4 ->\[\\Delta\] CO2 + 2SO2 + 2H2O}$$
