StructuralQuestions: Question 1. Displacement Reactions
Predict and explain briefly which of the following combinations does displacement reaction occur? For the ones do, write down what you expect to observe and the chemical equations.
When a freshly prepared aluminium object is exposed to air, an oxide layer is formed. Write down the chemical formula for the layer and the equation for its formation.
The oxide layer can protect the object from further reaction between the object and air. Therefore, we sometimes deliberately thicken this layer for stronger protection. What is the name of this thickening process? Draw a schematic diagram for carrying out this process.
Rust is formed on the surface of an iron object when it is exposed to humid air. Write down the chemical formula for rust and the equation for its formation.
