(a)

Complete set of apparatus and can be used and label

(b)

Zn + H₂SO₄ → ZnSO₄ + H₂

(c)

Experiment I = 0.167 cm³ s^-1

Experiment II = 0.267 cm³ s^-1

(d)

Number of moles of H₂SO₄ = = 0.002 mol

1 mol of H₂SO₄ produce 1 mol of H₂

0.002 mol of H₂SO₄ produce 0.002 mol of H₂

Maximum volume of H₂= 0.002 x 24 000 = 48 cm³

(e)

· The rate of reaction in experiment II is higher than that of experiment I.

· Copper(II) sulphate solution lowers the activation energy of the reaction in experiment II.

· The frequency of effective collisions between hydrogen ions and zinc atoms increases in experiment II.

(b)(i)	1. Fe⁺² → Fe⁺³ + e 2. Br₂ + 2e → 2Br – 3. Iron(II) ions lose electrons to become iron(III) ions. Iron(II) ions are oxidised 4. Bromine molecules gain electrons to form bromide ions. Bromine molecules are reduced (a: any suitable reducing agent) 1. Fe⁺³ + e → Fe⁺² 2. Zn → Zn⁺² + 2e 3. Iron(III) ions gain electrons to become iron(II) ions. Iron(III) ions are reduced 4.

My Isotopes

What is isotopes????

Ramai pelajar yang selalu memberikan jawapan yang tidak tepat tentang isotope. contohnya seperti berikut :

i)     Isotope have same proton number but different nucleon number
       ( mempunyai nombor proton yang sama tetapi nombor nukleon yang berbeza )
ii)    Isotope have same proton number but different number of neutron
   ( mempunyai nombor proton yang sama tetapi nombor neutron yang berbeza )

Kenapa jawapan di atas tidak tepat ???? Macam dah betul tapi kenapa tak dapat markah.....

Kata kunci paling penting adalah ATOM...Kerana satu perkataan markah hilang. Tersangatlah rugi.
So be careful. Inilah jawapan yang tepat...

Isotopes are atoms that have the same number of protons but different number of neutrons

or
atoms that have the same proton number but different nucleon number.
