Answer:
0.1334
Explanation:
The number of atoms per unit (n) is given by:
The atomic packing factor (APF) is:
Answer:
-14
Explanation:
You have to subtract 136 from 138 then subtract that from 12 & that is your low melting point.
The melting point (or, rarely, liquefaction point) of a solid is the temperature at which it changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure.

3. And that's it .
6.0 will the pH at the neutralization point of 0.00812 m Ba(OH)2 be when titrated with HCl.
<h3><u>What are </u><u>
titration reactions ?</u></h3>
A titrant/titrator, a standard solution with fixed volume and concentration, is prepared as part of the titration procedure. When an endpoint or equivalence point is reached, the titrant is made to continue reacting with the analyte, and at that point, the amount of titrant consumed may be used to calculate the analyte's concentration. Alternately, titration is the application of the stoichiometry principle to determine an unknown solution's concentration.
The technique begins by adding a very little quantity of analyte to a beaker or Erlenmeyer flask. Under a calibrated burette or chemical pipetting syringe containing the titrant, a little quantity of an indicator (such as phenolphthalein) is inserted.
