Intermolecular Forces. Forces Between Molecules. Intermolecular Forces. Electrical forces between molecules causing one molecule to influence another Heats of vaporization give a measure of the strength of attractions present between molecules

C H A P T E R   14 The Ideal Gas Law and Kinetic Theory. 14.1  The Mole, Avogadro's Number, and Molecular Mass . Atomic Mass Unit, U.

Properties of Water . Section 2–2. Objective. This section describes the makeup of water molecules. It also explains what acidic solutions and basic solutions are. The Water Molecule . Is the following sentence true or false? A water molecule is neutral. TRUE.

The properties of water. Life depends on them!. Water is polar. Polar molecules. Molecules are electrically neutral. Portions of a molecule can act as though they have an electrical charge if the components have different attractions for electrons. Polar molecules.

The Science of Water. We are surrounded by water; we are made of water. Water in our World. Water is necessary for life Water in our atmosphere helps to keep the planet warm Our bodies are composed of and dependent on water. A Quick Overview.

Chapter 2 The Chemical Context of Life. The three subatomic particles and their significance. The types of bonds, how they form, and their relative strengths. Overview. Living organisms and the world they live in are subject to the basic laws of physics and chemistry.

Acids, Bases, Salts and pH. Joe Walker Middle School Physical Science Hayhurst/Sour. Acids. Acids are chemicals in which the positive ion is a hydrogen atom. for example; HCl or H 2 SO 4

WHY CAN'T WE SEE ATOMS?. “seeing an object” = detecting light that has been reflected off the object's surface light = electromagnetic wave; “visible light”= those electromagnetic waves that our eyes can detect

GCSE: Extension Work A2 Level :Resonance. Cooking with Microwaves. Cooking with Microwaves. The microwave oven is well known as a fast, quick and efficient way of cooking food. Its invention has changed the way we cook in the home. Care when using the term ‘microwave’!.

Lecture 13: Mechanism of Chymotrypsin. Chemical Mechanism of Chymotrypsin. Chymotrypsin. Chymotrypsin is a digestive protease involved in breakdown of proteins and peptides so that their amino acids can be used. It is synthesized in the pancreas of mammals and released into

General Biology. Properties of Water. I. Water is an important topic to biologists Life on earth probably evolved in water . Living cells are 70% or more water. Water covers about 75% of the earth. In nature, water naturally exists in all three physical states of matter.

Chap. 5 part II Alkenes and Alkynes II: Addition Reactions Solomons, Chapter 8. Introduction: Additions to Alkenes Generally the reaction is exothermic because one p and one s bond are converted to two s bonds

Outline. Reminder Where were we? Capillarity. Soil Physics 2010. Reminder. Homework 1 is due. Soil Physics 2010. Uh-oh. Quiz. Soil Physics 2010. Where were we?. Solutes lower the water’s energy. Fresh water. Salt water. Water moves from higher (pure) to lower (salty) energy state.

Acids, Bases & Salts . Acid Properties : Sour taste, react with metals to produce hydrogen gas, electrolytes, affect indicators (turns blue litmus paper to red). Acids, Bases & Salts . Base Properties : Bitter taste, produce electrolytes, affect indicators (turns red litmus paper to blue).

THE GENERAL FEATURES OF T RANSITION METAL CHEMISTRY. G eneral features of transition metal s. This presentation explains what a transitio n metal is in terms of its electronic structure, and then goes on to look at the general features of transition metal chemistry. These include

Chemistry 11 Chemical Bonding. Electronegativity – the tendency of an atom to attract electrons from a neighbouring atom. . Get lost, loser!. Hey! I find your electrons attractive !. Electronegativity increases as you move from left to right. .

Daily TAKS Connection: Physical and Chemical Changes. IPC(8) The student knows that changes in matter affect everyday life. The student is expected to: (A) Distinguish between physical and chemical changes in matter such as oxidation, digestion, changes in states, and stages in the rock cycle.

Climatologists have many strategies for developing an understanding of patterns of climate change . Analyze Stable Isotopes. Many students are familiar with the use of unstable isotopes to “go back in time”. http://www.physlink.com/Education/askExperts/ae403.cfm.
