Particulate nature of matter and chemical change

Particulate nature of matter and chemical change has following keywords. Elements, Compound, Solution, Solvent, Solute,Homogeneous, Heterogeneous, Melting, Freezing, Boiling, Vaporisation, Condensation, Sublimation, Evaporation, Deposition, Proportion

This PPT on Particulate nature of matter and chemical change aligns with the IB Diploma Chemistry Guide. It covers the past paper questions on this subtopic.

Objectives: This PPT enables the students to apply their learning to : work with chemical equations by using the state symbols (s), (l), (g) and (aq), explain the observable changes during a phase change.

Guidance: You should include different types of equations for balancing and should discuss the above mentioned keywords.

Can you prove now that water is a compound?

Challenge: Is gas or vapour same?

 Why  or why not?

Try to write the state symbols of the following equations:

Ag+   + X−   → AgX(s)

Na2O + H2O → 2NaOH

 MgO + H2O → Mg(OH)2

Li2O(s) + 2HCl → 2LiCl  + H2O

MgO + 2HCl  → MgCl2 + H2O

P4O10+ 6 H2O→ 4H3PO4
