Chemistry Scene

Background

Chemistry Errors • “What do you get when lithium batteries react with potassium nitrate, that would be a covalent bond. . ” • Timing of reaction • Size of reaction

Ionic vs Covalent Bonds • Covalent Bond – Two non-metals – Similar electronegativity – Share electrons • Ionic Bond – Metal and non-metal – Opposite ions attract – Transfer of electrons

Ionic vs Covalent Bonds

KNO 3

Correct Information • “It has a crystalline structure” – Strong bonds between Potassium and Nitrate ions • “It can act as an oxidizer” – An oxidizer is a type of chemical which a fuel requires to burn. – accepts an electron from another species • “Key ingredient in gun powder” – combustion is a type of reduction reaction in which massive amounts of heat is released

Size of Explosion • Lithium would not be able to produce an explosion of that size. • Instead an alkali metal should have been used – more reactive potential

Timing of Reaction • The rate at which the reaction occurs depends on the required amount of activation energy – Generated from the reaction between lithium and water • Shaking of the bottle

The Explosion • Li (s) + H 2 O (l) → Li. OH (aq) +H 2 (g) – lithium is higher up in the reactivity series than hydrogen gas – alcohol is highly flammable and will combust with the hydrogen gas • Jenko shakes the bottle and agitates the solution • Reaction released the necessary activation energy to combust hydrogen gas and alcohol – The oxidizing agent KNO 3 provides the oxygen needed for the combustion reaction.
