Answer:
The correct answer is 240 atoms Na
Explanation:
According to the given scenario, the calculation of the number of sodium atoms reacted is as follows:
As we know that
The sodium reaction with [tex]O_3[/tex]
[tex]6Na + O_3 \overset{\Delta} \rightarrow} 3Na_2O \mhchem[/tex]
1 mole of [tex]O_3[/tex] reacted with the 6 moles Na attom
1 molecule [tex]O_3[/tex] [tex]\rightarrow[/tex] 6 atoms Na
40 molecule [tex]O_3 \rightarrow[/tex] 6 × 40 = 240 atoms Na
hence, the number of sodium atoms reacted is 240 atoms Na
Atoms of sodium will react completely with 40 molecules of O₃ is 240.
What is stoichiometry?
Stoichiometry of any chemical reaction tells about the relative amount of entities present in that reaction, before and after.
Given chemical reaction will be represent as:
6Na + O₃ → 3Na₂O
From the stoichiometry of the reaction it is clear that:
1 molecule of ozone = react with 6 atoms of sodium
So, 40 molecule of ozone = react with 40×6=240 atoms of sodium
Hence, required atoms of sodium is 240.
