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
