Question

I am so confused about this. Please some chemistry genius helps me.
Thank you in advance, you are special!

Answer 1

use law of conservation mass .

In a chemical reaction mass is neither created nor destroyed.

Hence Mass of reactants=Mass of products.

• Al=7.5g
• Cl_2=24.4g

Mass of Product:-

$\\ \sf\longmapsto 7.5+24.4$

$\\ \sf\longmapsto 31.9g$
