single replacement
A balanced chemical reaction.
The chemical reaction shown is a single displacement reaction, where magnesium (Mg) displaces hydrogen (H) in hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2).
The chemical reaction shown is a combination reaction, where two or more substances combine to form a single product. In this case, hydrogen gas (H2) and oxygen gas (O2) combine to form hydrogen peroxide (H2O2).
A chemical reaction.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
The chemical reaction shown is a double displacement reaction, where the cations and anions of the reactants switch partners to form new compounds. In this case, silver nitrate (AgNO3) and sodium chloride (NaCl) react to form silver chloride (AgCl) and sodium nitrate (NaNO3).
A waterfall is not a chemical reaction.
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)

A chemical reaction.
An exothermic reaction is one that proceeds with the evolution of heat.
