The equation I will use for this is: Mg(s) + 2Hcl(aq) + H2(g)

This reaction will happen when a magnesium ribbon is placed in a tube of hydrochloric acid, this then produces a hydrogen gas.

Prediction: I predicate that the stronger the concentration of hydrochloric acid the quicker the reaction time will be. The higher the concentration of hydrochloric acid, the more particles there will be and the more collisions there will be and the faster the magnesium will dissolve. The magnesium ribbon will only dissolve if the hydrochloric acid collides strong enough with the ribbon in order to break the bonds and dissolve the ribbon. Another thing which may speed up the reaction time is the temperature and concentration of each...
