J.J. Thompson is a British physicist who discovered the electron by a series of experiments which is designed to study the nature of a cathode ray tube. His discovery showed us that an atom can be split into smaller parts. He was a pioneer in the study of the model of an atom.
(2.4 x 10 24) divided by (6 x 10 23)=
Answer:
On the Moh's scale of hardness, aluminum oxide is positioned just below to diamond due to which it is considered as one of the hardest known compounds. This also shows that the compound exhibit an enormous amount of lattice energy, as to transform the oxide into its constituent ions, the energy is required to overcome.
Based on the chemical formula of the compound, that is, Al2O3, it is shown that the ions of Al3+ and O2- are kept close due to the activity of the strong electrostatic ionic bonds. The electrostatic forces and the ionic bonding between the ions are extremely robust due to the presence of the ions high charge density. Therefore, to dissociate the bonds, an enormous amount of energy is needed, and at the same time, a high amount of lattice energy is present.
The conversion factors she could use to calculate the cost of gas : 33.037 gallon from Baltimore to Orlando
She will spend $74.33 on gas
<h3>Further explanation</h3>
Given
Shonda’s car : 27 miles per gallon
Gas cost = $ 2.25/gallon
Distance Baltimore to Orlando = 892 miles
Required
Cost of gas
Solution
Total gallon needed to get from Baltimore to Orlando :
892 miles : 27 miles/gallon = 33.037 gallon
Cost of gas :
33.037 gallon x $2.25/gallon = $74.33
