Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

A Chemical change is any change that results in the formation of a new chemical substance. It is something that everyone learns about in school‚ but never really tries to see it in the real world. We all know the basic examples; baking a cake‚ burning wood… etc. What about the examples that are happening around us. For example‚ the Statue of Liberty has been through a chemical change. It was first a dull brown color‚ and now it is a green color. That happened due to a chemical change. During the

TECHNICAL PAPER A Practical Equation for Elastic Modulus of Concrete by Takafumi Noguchi‚ Fuminori Tomosawa‚ Kamran M. Nemati‚ Bernardino M. Chiaia‚ and Alessandro P. Fantilli Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus‚ the existing equations cannot cover the entire experimental

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

CHEMICAL ATTACK ON SYRIA Over 110‚000 people have died in Syria since the beginning of a years-long conflict in the country. On August the 21st‚ the U.S government says that 1‚429 died through the chemical attacks which marked the sea change in foreign policy towards the Middle Eastern country. The impact of poison gas is horrific and fatal. Those exposed to the nerve agent can die within 15 minutes of exposure.
