Answer:
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.

Atoms of one element are converted to atoms of another element through transmutation or nuclear transmutation.
Answer: Option A) 2 atoms
Explanation:
4Al + 302 ---> 2Al2O3
4 moles of Al reacts with 3 molecules of O2
So 1.10 moles of Al should reacts with Z molecules of O2 (Assume Z is unknown)
i.e 4 moles of Al = 3 molecules of O2
4 moles of Al = 6 atoms of O2 (since 1 molecule of oxygen has two atoms of oxygen)
1.10 atoms of Al = Z atoms of O2
To get the value of Z, cross multiply
Z x 4 moles = 6 atoms x 1.10 moles
4Z = 6.6
Divide both sides by 4
4Z/4 = 6.6/4
Z = 1.65 atoms (approximately 2 atoms)
Thus, 2 atoms of the excess reactant oxygen remains.
