An active metal is a metal that displaces hydrogen from an acid. Examples of active metals include magnesium, zinc and iron. This type of reaction is also called a single displacement reaction where the active metal 'displaces' the hydrogen from the acid. Examples of reactions involving acids and active metals. 1  Hydrochloric acid + Magnesium â Magnesium chloride + Hydrogen.
I am a transfer student and i don't understand how to do these formulas. 1. Write a balanced equation for the reaction in which dinitrogen pentoxide (N2O5) reacts with water to produce nitric acid (HNO3) 2. Phosphorus reacts with bromine to produce phosphorus tribromide (PBr3).Write the balanced equation for this reaction. 3. Magnesium reacts with titanium (IV) chloride (TiCl4) to produce magnesium chloride (MgCl2) and titanium.Write the balanced equation for this reaction. 4. Calcium hydride (CaH2) reacts with water to produce calcium hydroxide (Ca(OH)2) and hydrogen gas.
