The sugar is actually "dehydrated" by the acid. The result is a yucky carbon residue that is "fluffy." This means that it will expand significantly. The reason that it is so yucky is that it is wet with the (still very strong) acid.
Cu + 2 H2SO4 --------------> CuSO4 + SO2 + 2H2O
Magnesium sulfate is obtained.
2,4,6-trinitrophenol
maybe no reaction takes place;)
Even though toluene is not soluble in water, it is soluble in sulfuric acid due to its lower pka.

It actually deepens on the acid if it's sulfuric acid then it could disintegrate
ZnSO4 FORM AND HYDROGEN GAS RELEASE.

If highly concentrated, sulfuric acid reacts with cellulose to at least partially dehydrate the cellulose.
Even though toluene is not soluble in water, it is soluble in sulfuric acid due to its lower pka.
In most cases, hydrogen is the gas evolved as the result of an acid and a magnesium ribbon. But in some instances when it reacts with a concentrated acids, it may produce different gases as well. As an example, the reaction between magnesium and concentrated sulfuric acid produces sulfur dioxide.
Silver reacts with sulfuric and nitric acid.
Please be careful, do NOT use concentrated sulfuric acid. It gets far too hot, with expanding gases (CO2). (H2SO4)aq + (CaCO3)s --> (CaSO4)s + [H2CO3] --> (CO2)g + H2O
With the exception of boron which is unreactive , yes and each member of the group behaves differently. Silicon reacts to hot base and is almost unreactive to acid. Germanium and arsenic reacts to hot concentrated sulfuric and nitric but not to sodium hydroxide. Antimony reacts to nitric and sulfuric acid but not to base. Tellurium reacts to acids and bases.
