Indoor Air Pollution: Effects to Peoples Health Approximately 93% of our life we spend indoors (Vladimira Bukerova‚ personal communication‚ February 2012). Even though this may sound crazy it‚ is true. Weather people stay at home or at work; school or go for shopping they are inside of a building breathing‚ living the same air most of their daily life. There are different issues now days that are destroy our air and when talking about them people immediately will thing about the pollution caused

They way humans eat has changed more in the last fifty years than in the previous 10‚000. The film Food‚ Inc. sheds a ghastly light on corporate farming and the industrialization of the food industry. It uses several perspectives ranging from a chicken farmer that is cutting ties with oppressive Perdue‚ to inside the very plants that chemically treat massive amounts of meat to illustrate just how unnatural and dangerous today’s food can be. The movie is devided into three main segments. The first

I. Introduction There are two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the

Chapter 6: Chemical Bonds Section 6.1: Ionic Bonding Chemical bond: the force that holds atoms of elements and ions together to become a stable‚ new substance called a compound. -the number of valence electrons determines if an atom will form a chemical bond. -metals tend to give up electrons to other atoms. -nonmetals tend to take electrons from other atoms. -noble gases will not form a chemical bond because these atoms already have a full outer shell of energy.
