βοΈCOMMON 3/4M QUESTIONβοΈ
β οΈThose are NOT PREDICTED QUESTIONS. Please donβt depend too much on ramalan, we already experienced from sejarah rightπ Instead, learn how to study everything, we got this!!π₯
β€οΈF4C4β€οΈ
1. Why size of elements decreases across the period?
- Number of protons in the nucleus of an atom increases across the
period.
- Positive charge in the nucleus of an atom increases.
- Attraction force between nucleus and valence electron becomes stronger across the period from left to right.
π©·F4C5π©·
1. How metals can conduct electricity in solid state? (*Cu)
- Copper atoms are arranged closely packed and orderly in solid state.
- Positively-charged copper(II) ions are formed when valence electrons forms sea of electrons.
- Sea of delocalised valence electrons carries electrical charge from negative terminal to positive terminal when electricity is supplied.
- This movement of sea of delocalised electrons produce electrical current.
π§‘F4C6π§‘
1. Why different pH value for both acids? (*HCl&CH3COOH)
- Hydrochloric acid is a strong acid that ionises completely in water whereas ethanoic acid is a weak acid that ionises partially in water.
- Hydrochloric acid produces higher concentration of hydrogen ions than ethanoic acid.
- The higher the concentration of hydrogen ion, the lower the pH value.
- pH value of hydrochloric acid is lower than ethanoic acid.
πF4C8π
1. Why bronze is harder than pure copper?
- In pure copper, all copper atoms have same size whereas in bronze, copper atoms and tin atoms have different sizes.
- All copper atoms in pure copper are arranged in orderly manner whereas copper atoms and tin atoms in bronze are not arranged in orderly manner.
- When force is applied, layers of copper atoms in pure copper slide over each other easily whereas layers of copper atoms and tin atoms in bronze difficult to slide over each other.
πF5C3π
1. Why heat of combustion of ethanol is higher than methanol?
- Number of carbon atoms amd hydrogen atoms in ethanol is greater than methanol.
- More carbon dioxide gas and water molecules are formed in ethanol than methanol.
- More bond formation are formed in ethanol than methanol.
- More heat is released in ethanol than methanol.
2. Why heat of neutralisation of strong acid&alkali is higher than weak acid&alkali? *state the name specifically based on ques
- Strong acid and strong alkali ionises completely in water whereas weak acid and weak alkali ionises partially in water.
- Some weak acid and weak alkali remain as molecules.
- Some of the heat released during neutralisation is absorbed to completely ionise the weak acid and weak alkali in water.
3. Which one is better fuel (vehicle)?
*COMPARE from the aspect :
- Percentage of carbon atom per molecule
- Production of soot (Ex. X produces more soot than Y)
- Air pollution
- Production of carbon dioxide gas that causes environmental pollution
4. Which one is better fuel (cooking)?
*COMPARE from the aspect :
- Percentage of carbon atom per molecule
- Production of soot
- Production of carbon dioxide gas and water molecule
- Release of heat (Releases more heat, cook faster)
5. What happen to heat of precipitation when potassium sulphate is replaced with sodium sulphate?
- No changes (state the value when given)
- Number of moles of sulphate ions in sodium sulphate is the same as in potassium sulphate.
π©΅F5C4π©΅
1. Why vulcanised rubber is more elastic/better than unvulcanised rubber?
- Vulcanised rubber have strong sulphur cross-link between carbon molecules.
- This prevents rubber polymer from slidding when it is stretched.
- Rubber molecules return to its original shape after being stretched.
πF5C5π
1. What you should do when youβre prescribed antibiotics?
- One should fully consume the antibiotics.
- So that all bacteria can be killed.
- Otherwise, the bacteria will become immune to antibiotics and disease will recur.
*If you have questions, feel free to ask !!β€οΈ

hello ! assalamualaikum everyone . After batch 06 habis je SPM min akan susun semua room channel kita and pecahkan kepada subject . InsyaAllah akan lebih dari 30 Room Topic yang kita akan buat !
Selain dari tu, kita sediakan juga
β’Therapist Section
β’Bot Notes/Exercise (above 30 subjects yang ada)
And After SPM Party , kita akan anjurkan beberapa game untuk semua . But selepas batch 06 habis SPM sahaja . Contohnya
β’Tournament PUBG
β’Tournament ML
Untuk yang bakal menduduki SPM , kita akan anjurkan program berlandaskan pendidikan . InsyaAllah
so stay tuned semua , jangan lupa share our channel π
