Atom dan molecule are different tau.
Atom tu ada 1 je
Molecule is more than 1
- cth 1 : diatomic molecules (I2, H2, N2, O2, Cl2, Br2, F2)
- cth 2 : compounds (Al2O3)

Andddd jangan kita lupa kepada ION 😂

So, there are 3 types of particle, namely :
🧪Atom
🧪Molecule
🧪Ion

Faham dok?👀🙈

Hafal! Penting

Assalamualaikum and hello everyone! I would like to offer classes for chemistry and mathematics to all spm candidates. Contact me if interested.

Yokk jom jawab 1 quiz berkaitan alloy🤭

Malam nanti min Heera bagi penerangan kepada jawapan soalan ni inshaAllah✨

🧪Question : What is the effect of alloying pure gold ?

A. Become less hard
B. Easier to be shaped
C. Easier to melt
D. Does not corrode

⚗Explanantion for this question :

Soalan tanya effect alloying of pure gold.
Sah2 A dan C salah❌
🤖Alloying boleh buatkan metal tu lebih keras💪🏻 & melting point and boiling point pun akan meningkat⬆️🔴. So, it's difficult to melt bcs it requires high amount of heat🥵

🤔So, kita tinggal dgn B dan D ya
First of all, we MUST know that gold does NOT CORRODE.
Why??
👉because it is not a reactive metal.

⚡️Not reactive = Does not CORRODE
🍁Non-reactive metal susah nak terhakis. Hanya reactive metal is easily corroded

🌷The purpose of alloying pure gold is bukan nak jadikan dia tidak mudah terhakis😅
Tapi lebih kepada nak bentukkan dia jadi macam ii😉

Am I clear? 👀

🌷Electrolysis of Aqueous Solutions

Electrolysis of : CuSO4💙 solution using copper electrodes (active electrode)🤎

......

Question : Why the blue colour of CuSO4 solution does not change? 💙

✨Answer (pg 44 tb)
🫐The concentration of copper (ii) ions, Cu2+ remains the same.
🫐The rate of ionisation of copper, Cu at the anode is the same as the rate of discharged copper(ii) ions, Cu2+ at the cathode.
