MATTER - PROPERTIES AND TRANSFORMATION: Chemistry Of Elements - Transition metals
What is the colour of copper(II) carbonate?
Blue.
Black.
Green.
White.
Why do transition metals form coloured compounds?
They form ionic bonds.
They are highly reactive.
They have very high ionization energies.
They have empty d-orbitals which allow for electron transitions that absorb specific wavelengths of light.

Dehydration.
Neutralization.
Oxidation.
Reduction.
When iron reacts with chlorine gas, what is the product?
Iron(III) chloride.
Iron(II) chloride.
Iron(II,III) chloride.
Iron(I) chloride.
Which property best explains why copper is used extensively in electrical wiring?
Excellent electrical conductivity.
High malleability.
Lustrous appearance.
Good ductility.
