Point source, not a non source
I think that, considering that a mole contains an Avogadro's number of elements, there should be 6.2× an Avogadro's Number of atoms of Al. 6.2×6.022×1023=3.733×10<span>24 atoms</span>
⭐《ANSWER》
↪To know that a molecule is polar or non-polar
↪we will look that , does it contain the Electronegative elements that can create a partial positive or Negative charge, such as the HALOGENS
↪after this , also we can observe that , is there any amonia group or a carboxylic group that can create a positive or negative charge by transfer or acceptance of the Hydrogen atom
↪Also in case of the amino acids when the, acids are mixed in soluble solvent there is charge transfer , due to which there is formation of

Answer:
All groups have the same number of valence electrons.
Explanation:
groups are the columns.
There are actually 5 skills
in applying Hess’ Law. According to science.uwaterloo and chem.libretexts.org
these are the 5 skills.
- changing the enthalpy of
the reaction whenever the equation changes
- interpreting the Hess’ Law
- applying the principle of
conservation of energy to solve the problem
- sketching an energy diagram
for any related reactions
<span>- and lastly using the
diagram to explain the Hess’ Law.</span>
