Answer:
No, the model does not demonstrate the conservation of matter
Step-by-step explanation:
The principle of conservation of matter states that matter can neither be created nor destroyed but is transformed from one form to another.
If we look at the model presented, the products on the right hand side and the reactants on the left hand side, we will notice that there is a loss of matter from left to right.
As a result of this, the model does not show the principle of conservation of matter.
