Concept explainers
(a)
Interpretation:
Sucrose (table sugar) has to be labelled as either a pure substance or a mixture.
Concept Introduction:
Pure substance:
A pure solution is made of a single component.
Example:
Water is pure substance as it contains two hydrogen atoms and one oxygen atom.
Mixture:
A mixture is said to be a combination of two or more pure substances which retains their own identities.
Mixture may be a homogeneous mixture or heterogeneous mixture.

- when a 0.150 g sample of the compound was burned, it produced 0.138 g CO2 & 0.0566 g H2O. All the nitrogen in a different 0.200 g sample of the compound was converted to NH3, which was found to weigh 0.0238 g. Finally, the chlorine in a 0.125 g sample of the compound was converted to Cl- and by reacting it with AgNO3, all of the chlorine was recovered as the solid AgCl. The AgCl, when dried was found to weigh 0.251 g.
