Sheep were the basis of their wealth, and by 1850 there were more than 15 million head in Australia. Squatting was legitimized in 1836, after the British government recognized the impossibility of enforcing the original settlement restrictions.
When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
Explain why ionic compounds do not conduct electricity in their crystalline form. Electricity can only be conducted when ions are freely moving in separate positive and negative charges (as in the aqueous form and molten form). In their crystalline form, the ions in the ionic compound are locked tightly in one place and the positive and negative balance out to make the overall structure neutral.
