Unit Chemistry 3
At the beginning of each sub-section, activities are stated which develop candidates. skills, knowledge and
understanding of how science works. Details are then given of the substantive contexts in which these skills,
knowledge and understanding should be set. It is
expected that, where appropriate, teachers will adopt a practical approach enabling candidates to develop
skills in addition to procedural knowledge and understanding.

Compared with the elements in Group 1, transition elements:
- have higher melting points (except for mercury) and higher
- are stronger and harder
- are much less reactive and so do not react as vigorously with
water or oxygen.
Many transition elements have ions with different charges, form
coloured compounds and are useful as catalysts.

The solubility of most solutes that are solids increases as the temperature increases.
A saturated solution is one in which no more solute will dissolve at that temperature. When a hot
saturated solution cools, some of the solute will separate from the solution.
Many gases are soluble in water. Their solubility increases as the temperature decreases and as the
pressure increases.
- Dissolving carbon dioxide in water under high pressure makes carbonated water. When the pressure is
released, the gas bubbles out of the solution.…read more

In an exothermic reaction, the energy released from forming new bonds is greater than the energy needed
to break existing bonds.
In an endothermic reaction, the energy needed to break existing bonds is greater than the energy released
from forming new bonds.

Thanks. I liked it tbh, despite the fact it is according to the old syllabus.
