Answer

Explanation:

Step1: Recall element definition

An element is a pure - substance made of only one type of atom.

Step2: Recall compound definition

A compound is a pure - substance made of two or more different types of atoms chemically combined.

Step3: Recall mixture definition

A mixture is a combination of two or more substances that are not chemically combined.

Diamond (C): E (Carbon is an element) Sugar ($C_6H_{12}O_6$): C (Made of carbon, hydrogen, and oxygen atoms chemically combined) Milk: M (Contains water, fats, proteins etc. not chemically combined) Iron (Fe): E (An element) Air: M (Mixture of nitrogen, oxygen, carbon - dioxide etc.) Sulfuric Acid ($H_2SO_4$): C (Made of hydrogen, sulfur, and oxygen atoms chemically combined) Gasoline: M (Mixture of hydrocarbons) Electricity: X (Not an element, compound or mixture) Krypton (K): E (An element) Bismuth (Bi): E (An element) Uranium (U): E (An element) Popcorn: M (Contains different substances like carbohydrates, water etc.) Water ($H_2O$): C (Made of hydrogen and oxygen atoms chemically combined) Alcohol ($CH_3OH$): C (Made of carbon, hydrogen, and oxygen atoms chemically combined) Pail of Garbage: M (Mixture of different waste materials) A dog: X (Not an element, compound or mixture in this context) Ammonia ($NH_3$): C (Made of nitrogen and hydrogen atoms chemically combined) Salt (NaCl): C (Made of sodium and chlorine atoms chemically combined) Energy: X (Not an element, compound or mixture) Gold (Au): E (An element) Wood: M (Mixture of cellulose, lignin etc.) Bronze: M (Alloy, a mixture of copper and tin) Ink: M (Mixture of dyes, solvents etc.) Pizza: M (Mixture of flour, cheese, toppings etc.) Dry Ice ($CO_2$): C (Made of carbon and oxygen atoms chemically combined) Baking Soda ($NaHCO_3$): C (Made of sodium, hydrogen, carbon, and oxygen atoms chemically combined) Titanium (Ti): E (An element) Concrete: M (Mixture of cement, sand, gravel etc.)
