How to differentiate Alkane (Saturated Hydrocarbon) with Alkene (unsaturated hydrocarbon)???

Alkane - A has one line through, therefore (C - C)
AlkEne - E has more than one like, therefore (C=C) or triple covalent bond (C (triple line) C)

Lampakk je there's a single bond with more than one stroke, it's immediately unsaturated!

For example..

Saturated because its all with a single bond (C-C) - Alkane

Unsaturated because its more than one bond (C=C) - Alkene

Maaf yaa, Kak rai agak sibuk beberapa hari nii

Sementara tu, korang boleh jawab quiz science form 4, so that I know which topics to discuss in the future!

Selamat bersahurr!! Kak Rai noticed how some of you are weak with how to answer questions during exams — especially when it comes to science process skill..

RV - Responding Variable

I apologise for not being activee!! Im very busy with life.. Shall we focus on how to answer questions today?

When to use SEEN RV -
- Observation
- Prediction
- Prove
- Hypothesis

When to use UNSEEN RV -
- inference
- conclusion
- Hypothesis

When answering a question, they tend to twist the words a bit to see your level of understanding.. Dont be fooled and switch them up!!

Remember, despite already knowing the Unseen rv, we must answer based on the level we are given in the question..

Example —
Raju made an experiment based on unwashed hands streaked on a petri dish with nutrient agar. Predict the state of the nutrient agar after 3 days.

The state of the nutrient agar after 3 days will be cloudy (seen rv) 👍

The state of the nutrient agar will have presence of bacterial colonies (Unseen rv) ❌

Hi guys, good evening ☺️
Sorry sebab tak ada update apa-apa lepas buat poll hari tu. Ramadan is much busier than I expected and I was not ready for it 💔

But as I promised before, sebab ramai yang vote Bab 8 Tingkatan 4 susah, so I nak share nota dengan korang.

Nota ni tulisan tangan saya masa Form 4 dulu, so dia agak comot and sangat ringkas. Nanti saya akan buat nota yang baharu untuk korang semua. Lepas tu saya akan divide kepada beberapa bahagian dan buat explanation sekali.

Then, korang boleh guna nota baharu tu untuk quick revision 😁
