Question

1. when a liquid becomes a gas below its boiling point, this is called: a. condensation b. boiling c. freezing d. evaporation part c: application & analysis (short answer - 1 pt each) classify the following as element (e), compound (c), homogeneous mixture (hm), or heterogeneous mixture (ht): 11. a. orange juice: ___ 12. b. carbon dioxide: _ 13. c. trail mix: _ 14. d. water (h₂o): _ 15. e. iron (fe): ___

Explanation:

Evaporation is the process where a liquid changes to a gas below its boiling - point. An element is a pure substance made of only one type of atom. A compound is made of two or more different types of atoms chemically combined. A homogeneous mixture has a uniform composition throughout, and a heterogeneous mixture has a non - uniform composition. Orange juice is a homogeneous mixture as it appears uniform. Carbon dioxide is a compound as it is made of carbon and oxygen atoms. Trail mix is a heterogeneous mixture as it has different components like nuts, raisins etc. that are not uniformly distributed. Water is a compound made of hydrogen and oxygen. Iron is an element as it is made of only iron atoms.

3. b. C
4. c. HT
