Answer 8

Cu+H2So4

Answer 9

When copper reacts with H2SO4, it gives CuS04.5H20 which is blue in colour

Answer 10

It is a characteristic reaction of copper

Answer 11

copper is a metal. Bonding in copper is mettalic bond. Its valence electrons are free to move in the crystal lattice. The probability of finding the electron all over the crystal is the same. The electrons behave as free electrons whereas the copper nucleus with its core electron are frozen in the lattice. So it is a good conductor of electricity. Copper is a good conductor of heat too.
