Hello Mate!
Well, there are many definitions and descriptions of isolated systems, and here are some of them:
1. It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2. It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
I Hope my answer has come to your Help. Thank you for posting your question here in

The mass of MgCl₂ produced is 5.685 grams.
<h3>What is mass?</h3>Mass is the quantity of matter of a physical body.
The reaction is
Mg + 2HCl → MgCl₂ + H₂
2 mole of HCl
(2 × 36.458) = 72.8 g
1 moles of MgCl₂
(1 × 95.21 g) = 95.21 g
1 g Mg will produce =
4.67 mol Mg will produce
Thus, the mass of MgCl₂ produced is 5.685 grams.
