Study Notes

Properties of Metals

Most metals are strong and flexible.
Light metals are generally weaker than heavier metals.

Metal and Oxygen Reactions

Metals react with oxygen to form metal oxides.
For example, zinc reacts with oxygen to form zinc oxide.

Metal and Halogen Reactions

Metals react with halogens to form metal halides.
For example, zinc reacts with fluoride to form zinc fluoride.

Catalysts

Catalysts speed up chemical reactions without being consumed in the process.

Science Experiment

Copper acts as a catalyst in the reaction between zinc and sulfuric acid, speeding up the reaction.
Catalyst converters in cars utilize catalysts to convert harmful gases into less harmful ones.
