Chemical property is when it's observed during a reaction in which the chemical composition or identity of the substance is changed. physical properties is when properties that do change the chemical nature of matter.
example for this is smell, color, freezing point, etc.

Answer :
Explanation :
The aluminium and fluorine react to give ionic compound aluminium fluoride.
Aluminium has 1 valence electrons in their shell and fluorine has 7 valence electrons in their shell.
For the complete octet, both aluminium and fluorine exchange valence electrons to form an ionic compound.
The aluminium donates its three valence electrons to three fluorine atoms and they form one and three ions.
Electron transfer image is shown below.
In order to answer this question, the dimensions of the brick in centimeters need to the converted to dimensions in meters. In order to convert centimeters to meters you need to divide by 100. Doing this yields brick dimensions of 0.15 m x 0.06 m x 0.12 m. Multiplying the length, width and height together yields the volume of 0.00108 cubic meters.
