Organic VS. Conventional Alexis Dossey Environmental Science 1A For years‚ there has been a debate on how food is grown. Should it be organic or conventionally grown? To answer this question‚ the difference between the two needs to be known. Organic produce is grown without chemical fertilizers and pesticides. Organic livestock is free ranged‚ most of the time‚ with no added antibiotics or growth hormones. Conventionally grown produce is usually

Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics

Introduction Representing molecules as images allows us to impart a great deal of information concerning molecular structure. But these molecules can also be named‚ and there are occasions when this is more convenient than drawing a picture. In the early days of chemistry‚ the list of known compounds

Sustainability and Organic Foods People nowadays are getting into the “go green” lifestyle while others continue to live without thinking about the effects they have on the environment. Why do people go green? It can save you money‚ it is the right thing to do‚ it is healthier because there are less toxins and less illness‚ it is helping future generations‚ and it is a chance to connect with the local community and spread the word. To go along with this lifestyle and its benefits‚ catering companies

INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical bonding

Organic Chemistry Project: Designing molecules In order to understand the complexity and shape of an organic molecule you and your partner will be constructing a 3-D version of a selected organic compound. The project will have four parts: A blueprint of the molecule you will construct The molecule A legend explaining the structure of the molecule A paragraph explaining the importance of the molecule This project will count as one lab grade. A sample grade sheet is on the back.

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds
