The magnesium metal has reacted completely:

Gas bubbles are no longer produced.
The magnesium metal is gone.

When the magnesium ribbon reacts with hydrochloric acid magnesium chloride is formed and hydrogen gas is released. The temperature of the test tube changes, slight bubbles are generated, and the magnesium ribbon dissolves in the water and turns blue.

Magnesium reacts with acids to produce visible hydrogen gas bubbles. The combustion of magnesium is an exothermic reaction because energy is released into the environment when particles of magnesium and oxygen collide and form new bonds. Citric acid and baking soda are endothermic when the temperature drops. Magnesium and hydrochloric acid generate heat when the temperature rises.
