The degree of polarity of diatomic molecule is related to the difference of electronegativity of the two atoms. If the difference is very large, i.e. one atom is highly electronegative and the other atom is highly electropostive then, the covalent bond is formed. But if the difference between the electronegativities is very less, then its likely that ionic bond is formed.
Answer;
It indicates that it is a metallic luster
Explanation;
-The physical properties of minerals comprise various measurable and discernible attributes, including color, streak, magnetic properties, hardness, crystal growth form, and crystal cleavage. Each of these properties are mineral-specific, and they are fundamentally related to a particular mineral’s chemical make-up and atomic structure.
-Mineral crystals form in many different shapes and sizes. A mineral is made up of atoms and molecules. As the atoms and molecules combine, they form a particular pattern.
The enthalpy change of the precipitation reaction is 84 kJ/mole
Why?
The chemical equation for the reaction is
AgNO₃(aq) + NaCl (aq) → AgCl(s) + NaNO₃(aq)
To find the enthalpy change we need to apply the following equation
To find the heat (Q):
Now, to find the number of moles that react (n):
![n=[AgNO_3]*v(L)=(0.1M)*(0.05L)=0.005moles](https://tex.z-dn.net/?f=n%3D%5BAgNO_3%5D%2Av%28L%29%3D%280.1M%29%2A%280.05L%29%3D0.005moles)
Having these two values we can plug in the first equation:
Have a nice day!
It sounds to me like "A" is the answer. Yup, it is
