A pizza is composed of what elements?

A pizza, like all food, is ultimately composed of the same basic chemical elements found in the universe. Here's a breakdown:

Major Elements:

* Carbon (C): The backbone of carbohydrates (in the crust, sauce, and cheese), fats (in the cheese), and proteins (in the cheese and toppings).

* Hydrogen (H): Found in water and all organic molecules.

* Oxygen (O): A component of water, carbohydrates, and fats.

* Nitrogen (N): Found in proteins.

* Calcium (Ca): A major component of cheese, which also contains calcium phosphate.

* Sodium (Na): Found in salt, which is used to season the dough and sauce.

* Potassium (K): Found in some vegetables used as toppings.

Minor Elements:

* Phosphorus (P): Found in fats, proteins, and cell membranes.

* Sulfur (S): Found in some proteins.

* Magnesium (Mg): Found in some vegetables.

* Iron (Fe): Found in some meats used as toppings.

* Zinc (Zn): Found in some toppings like mushrooms and pepperoni.

Trace Elements:

* A very small amount of other elements like copper, manganese, selenium, and iodine might be present, depending on the ingredients used.

It's important to remember that the specific composition of a pizza can vary greatly depending on the recipe, ingredients, and how it's prepared.
