Answer

Brief Explanations:

When magnesium, aluminum, and calcium react with concentrated hydrochloric acid, hydrogen gas is produced. Hydrogen is highly flammable and can ignite in the presence of sparks, open flames, or high - heat sources. Hydrochloric acid does not break down due to heat in this context and heat does not directly cause the acid to produce a salt in a way that would require these safety warnings.

Answer:

Hydrogen gas is highly flammable.
