Vote for the Strongest Woman !!!. Contestant #1. Contestant #2. But first….. What do we remember about the physical properties of substances? (things that have definite and uniform chemical compositions) . Let’s see…. Similar substances have identical:. Color and odor.

CHEM/TOX 336 Lecture 11/12. Dissolved Gases in Natural Water Dissolved Solids in Natural Water. Solubility of gases in water: Henry’s Law. concentration dissolved / partial pressure of the gas K H (units mol L -1 atm -1 ) = c X / p X Large K H means high solubility

TEXTURE OF ROCK. THE SIZE, SHAPE AND POSITIONS OF THE PIECES INSIDE A ROCK.. 3 TYPES= FINE GRAINED, COARSE GRAINED AND MEDIUM GRAINED ROCKS ARE MADE OF MINERALS, BUT MINERALS ARE NOT MADE OF ROCKS. FINE GRAINED TEXTURE. WE DON’T EASILY SEE WHAT IS INSIDE THE ROCK..

Identifying Minerals. Each mineral has its own specific properties used to identify it. Color. The same mineral can come in a variety of colors Ex. quartz Impurities & other factors can change mineral appearance Color is not the best way to identify minerals.

Chapter 1: Minerals of the Earth’s Crust. A mineral is a naturally occurring, inorganic solid that has a definite chemical composition and a crystal structure.
