4. Jessica heated some bright blue copper(II) nitrate crystals in a test-tube. She noticed
brown nitrogen dioxide gas being produced. When a glowing splint was held at the
top of the test-tube, it relit, proving that oxygen gas was also produced. A fine black
solid, copper(II) oxide, was left in the test-tube.
