The net reaction is Zn(s) + 2H +(aq) → Zn2+(aq) +H 2(g) The Cl− ions are spectators - they don't change. This experiment includes the reaction of zinc with hydrochloric acid.
An object is thrown vertically from the ground upwards with a speed of 10 m/s. Considering g = 10 m/s2, the maximum height that the object reaches from the ground, in meters, will be:
