Copper is a coinage metal having high value of std reduction potential (positive) or negative value of std oxidation potential. So, when copper is heated with conc.H2SO4, a redox reaction occurs and the acid gets reduced to sulphur dioxide. Reaction is H2SO4+CuO ———→CuSO4+H2O. How does sulfuric acid react with copper oxide?

HNO3 is a protic acid and H2SO4 is a diprotic acid, this means that while HNO3 donates a single H+ H2SO4 donates 2 H+ ions. HNO3 is highly volatile as compared to H2SO4. The components are different, the molecular weights and melting point and boiling points are different.

The thermite reaction basically is an example of what happens when metal burns. What happens if you perform the thermite reaction on a block of ice? You get a spectacular explosion! The reaction is so stupendous that the Mythbusters team tested it and verified it was real.
Put on your lab goggles and start learning chemistry with these resources. Find instructions for chemistry experiments and learn about chemical reactions, elements, and the periodic table in this collection. Teachers can also find chemistry resources for the classroom.
A fast way to answer it is that HNO3 is soluble in water and water is polar so HNO3 is polar Another explanation is that HNO3''s H will form dipole hydrogen bonds with other molecules (IMF) thus is

All concentrations are given in weight-% and the solvent is water if nothing else is shown.
Question:When aluminum foil is placed in hydrochloric acid, nothing happens for about 30 seconds or so.This is followed by vigorous bubbling and the eventual disappearance of the foil. Explain these observations. Answers:The reaction that occurs is 2 Al + 6 HCL ---> 2 AlCl3 + 3 H2 So the bubbling gas is hydrogen.The reason there is a slight delay is that aluminum forms a very thin oxide layer
Since S8 molecule is larger than O 2 molecule, the van-der Waals force between the S8 molecules is stronger than that between the O 2 molecules and the melting point of sulphur is also higher than that of O 2. Hence sulphur exists as solid and O 2 exists as gas. iii. Sulphur trioxide is not directly dissolved in water to manufacture H 2 SO 4.
