Answer: The property is called Luster
Explanation:
Luster is a term used to describe the appearance of light from the surface of the mineral when it reflects light. The two types of classification of Luster is Mettalic or Non Mettalic.
some examples of minerals with mettalic lustre are --- Galena, graphite, Gold, Silver, Copper etc
Some examples of minerals with non mettalic lustre are--- Barite, Serpentine, Fluorite etc.
Explanation:
For this question, we apply the equation: Q = mCp AT Where m is the mass of the substance, Cp
is its specific heat capacity and AT is the
temperature change. Q = 896 x 0.45 x (5-94)
Q = -35884.8 Joules
So about -36 kilojoules of heat is released.

The compound that dissociates to produce the ions SO4^-2 (aq) and NH4+ IS (NH4)2SO4 (s).
(NH4)2SO4 is an ionic compound that dissociates itself upon its addition to the solvet to form a solution. When it is in the solution it forms ions.
The dissociation of ammonium sulfate forms 2 moles of ammonium ions (NH4+) and 1 mole of sulfate ion (SO4^2-).
That is; (NH4)2SO4 = 2 NH4+ + SO4^-2
Answer:
Temperature
Explanation:
The kinetic energy is proportional to the temperature. That is, temperature is a measure of the kinetic energy of atoms and molecules that are part of a system.
This can be explained by kinetic theory.
