Mass of chlorine reacted : 7.1 g
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2Na(s) + Cl₂(g) → 2NaCl(s).
mol Na :
[tex]\tt \dfrac{4.6}{23}=0.2[/tex]
mol NaCl :
[tex]\tt \dfrac{11.7}{58,44 }=0.2[/tex]
limiting reactant = Na(mol NaCl from mol Na, mol ratio : 2 : 2)
mol Cl₂:mol Na=2:1
mol Cl₂ =
[tex]\dfrac{1}{2}\times 0.2=0.1[/tex]
mass Cl₂ :
MW Cl₂ = 71 g/mol
[tex]\tt 0.1\times 71=7.1~g[/tex]
