Verified step by step guidance1
Recall the basic classifications of matter: elements, compounds, mixtures, and solutions. Elements consist of only one type of atom, compounds are substances made of two or more elements chemically bonded, mixtures contain two or more substances physically combined, and solutions are homogeneous mixtures.
Consider the nature of pizza: it contains various ingredients such as dough, cheese, sauce, and toppings, each of which is a different substance physically combined but not chemically bonded.
Since the ingredients in pizza retain their individual properties and can be physically separated, pizza is not a compound or an element.
Pizza is not a solution because it is not a homogeneous mixture; its components are visibly distinct and not uniformly distributed.
Therefore, pizza is best classified as a mixture because it is a physical combination of different substances without chemical bonding.
