Topic 36 - Atmosphere and the Environment

Hello!

Here is [Powerpoint presentation] used in class for this week.

Don't forget to do your revision on the 4 Chemistry topics:
- Atomic Structure
- Ionic Bonding
- Covalent Bonding
- Writing Formulae and Chemical Equations


If you still need help on the Physics Topics that we covered last week for revision, please PM me through WA or you can ask directly this Thursday/Saturday.

Topic 33 - General Wave Properties, Topic 34 - Light, Topic 35 - Electromagnetic Spectrum

Hello! Here is the Powerpoint for

Topic 33: [General Wave Properties]

Topic 34: [Light]

Topic 35: [E.M spectrum]

Topic 24 - Transport of Thermal Energy, Topic 25 - Temperature and Topic 26 - Thermal Properties of Matter

Here's the notes for the new Physics topics we are currently covering.

Topic 20: Acid, Base and Salts notes

Salam and good morning!

Here are the lesson objectives:

• describe the meanings of the terms acid and alkali in terms of the ions they contain or produce in aqueous solution
• describe the characteristic properties of acids as in their reactions with metals, bases, carbonates and their effects on indicator paper
• describe the characteristic properties of bases as in their reactions with acids and with ammonium salts and their effects on indicator paper
• describe neutrality, relative acidity and alkalinity, and neutralisation in terms of pH (whole numbers only), measured using Universal Indicator paper
• describe and explain the importance of controlling acidity in soil
• classify oxides as either acidic, basic, or amphoteric related to metallic/non-metallic character
• describe the preparation, separation and purification of salts as examples of some of the techniques specified in topic 1.2(c): methods of preparing salts to illustrate the practical techniques should include the action of acids with insoluble bases, and acids with insoluble carbonates
• suggest a method of preparing a given salt from suitable starting materials, given appropriate information

Here is the link to the notes for this topic: [PowerPoint] [Word Document].

Please don't forget the important reactions and its names.

Combined Science - Feeling lost with the current topics?

At the moment, we are covering Topic 20 - The Chemistry of Acid, Bases and Salts. This is a chemistry topic. You can have a look at all of the topics we are going to cover here.

This topic is a continuation from Atomic Structure, Ionic and Covalent bonding and Chemical Formulae and Equations.

I have found a few video clips on youtube to guide you through these topics, just in case you have forgotten:

Atomic Structure -

• Parts of an atom 
• The nucleus
• What are electrons?

• Atomic number and mass number (in the Periodic Table)
•  What are ions?
• Isotopes

Bonding

• What are ionic bonds
• Covalent bonds (Part I) and (Part II)

Chemical Formulae and Equation

•  Formulae of ionic compounds (Part I)and (Part II (polyatomic ions))
• Calculating Mass

The Chemistry of Acid, Bases and Salts

• Acid-Base Reactions in Solution
• pH and indicators 

These video clips are at most 5 minutes and some are about 15 minutes, so do take time to watch them in your free time.
Oh! and just for fun, EXPLOSIONS! and Sulfuric Acid reaction with sugar!

What did you think of these videos?

Slides on Topic 2 - Kinematics (Physics) and Topic 20 - Acid, Bases and Salts

Hello!

For those of you who are eager to do some reading before the actual lessons, you can view the slides which I will be using here:

Physics Topic 2 - Kinematics
Combined Science Topic 20 - Chemistry of Acids, Bases and Salts

I will be updating these files to my liking, if needed. Thank you. :D

Combined Science Topic 19 - Chemical Formulae and Equation and Physics Topic 1 - Physical Quantities, Units and Measurements

Hello!
These are the notes for this topic. So feel free to download them through this link:

[Combined Science] Calculation of Mass Exercise
[Combined Science] Periodic Table

Thanks to Cg. Lim Ming Han, I now have the notes for Physics. I've edited his notes abit (just changed the font), but thats about it. You 9Sci2-ers can download it through:
