Pioneer species are the first species to arrive in an area after succession (hope this helped because i dont know about climax communities)
As per the given chemical formula- Na2CO3.10H2O, one mole of the chemical compound contains 13 moles of oxygen atoms. Hence
Number of moles of oxygen atoms in one mole of Na2CO3.10H2O = 13
number of moles of oxygen atoms in 0.2 moles of Na2CO3.10H2O = 13 X 0.2 = 2.6
Now, one mole of a substance contains 6.022 X 10^23 particles of the substance. Thus
number of atoms of oxygen in one mole of oxygen atom = 6.022 X 10^23
number of moles of oxygen atoms in 2.6 moles of oxygen atoms = 2.6 X 6.022 X 10^23 = 15.657 X 10^23
= 1.566 X 10^24
Thus, there are 1.566 X 10^24 atoms of oxygen in 0.2 moles of Na2CO3.10H2O.

Answer:
Four
Explanation:
AlCl₃(aq) ⟶ Al³⁺(aq) + 3Cl⁻(aq)
One mole of AlCl₃ produces 1 mol of Al³⁺ and 3 mol of Cl⁻.
That's four moles of ions.
