The sandwich example relates to the Law of Conservation of Matter for Chemical Equations. Matter cannot be created nor destroyed. This is why there must be the same number of atoms on the reactant side as on the product side. Looking at the image below, does it demonstrate the Law of Conservation of Matter? Explain why.
The image below shows a sandwich being made with bread, cheese, and ham. This image does demonstrate the Law of Conservation of Matter because even though the ingredients are being rearranged (bread, cheese, and ham going into the sandwich), the total number of atoms of each element (carbon, hydrogen, oxygen, etc.) remains the same. The bread, cheese, and ham are simply being rearranged to form a sandwich, but the total mass of the sandwich ingredients remains the same. This aligns with the Law of Conservation of Matter, which states that matter cannot be created nor destroyed, only rearranged.
Therefore, this sandwich example is a good demonstration of the Law of Conservation of Matter for Chemical Equations.

Make this into a rap
Yo, listen up, I got a lesson for you,
About the Law of Conservation, something that's true.
We're making a sandwich, with bread, cheese, and ham,
But remember one thing, matter ain't no scam.
The atoms in the bread, and the cheese, and the ham,
They ain't disappearing, they ain't in no jam.
They're just getting mixed up, to form a new creation,
But the total mass stays the same, that's the foundation.
Law of Conservation, it's a chemical delight,
No matter's created or destroyed, it's all right.
So next time you make a sandwich, just remember this fact,
Matter's always conserved, that's a scientific pact.
So groove to this rap, and keep it in your brain,
Law of Conservation, it ain't no pain.
From bread, cheese, and ham, to a sandwich so fine,
Matter stays the same, every single time.
