Physical properties of a substance include, solubility, boiling point, etc.
The correct matching of the physical properties with definition is as follows;
- Solubility - the ability of a substance to dissolve in another
- Boiling point - the temperature at which a liquid becomes a gas
- Density - the amount of mass in a given volume
- Buoyant force - the upward force on an object in a fluid
- Conductivity - the ability of a substance to transfer heat or electricity
Above, all the physical properties have been properly matched with the corresponding definitions.

Answer:
32.57g
Explanation:
mass = mole x molar mass
mass of LiBr = 0.375 x 86.85
mass = 32.57g
Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
Answer:
Modern periodic law
Explanation:
There are many ways of stating the modern periodic law. Generally, the modern periodic law states that the properties of elements are a periodic function of their atomic numbers. That means, similar properties recur periodically when elements are arranged according to increasing atomic number.
Two scientists were largely responsible for our present day understanding of the modern periodic law, they are, Mendeleev and Moseley. Their work laid the foundation for the periodic table in its current form.
