Ionic compound: is a chemical compound in which ions are held together by lattice structure by ionic bonds Types of Radiations: Alpha‚ Beta and Gama Half life - The time taken for the radioactivity of a specified isotope to fall to half its original value. Characteristics of living things: reproduces‚ respiration‚ Organic matter refers to that matter which is form a once a living organism and is capable of decay. It also entails the composition of organic compounds. Organic matter comes from

The Parthenon reflects the climax of the Ancient Greek architecture because of the balance and the elegance of the enormous building. The Temple was build between 448 and 432 before Christ‚ during the Ancient Greek Period and is an example of the Ionic temple architecture. Phidias built the temple for the Greek goddess Athena pathenos. The architects were Iktinos and Kallikrates. They began building in 447bc and finished in 431bc. It was built on the Athenian Acropolis and is considered the most

example of a binary compound. Several other examples are listed below. Potassium bromide KBr Calcium bromide CaBr2 Lithium fluoride LiF Lithium oxide Li2O When naming binary compounds follow these rules: 1. the element with the positive ionic charge is written first. 2. The second word is formed by changing the ending of the name of the element to “ide.” For example‚ bromine changes to bromide. Metals usually have positive charges while nonmetals (when combined with nonmetals) have negative

called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly soluble such as CH3COOH‚ under acids we have HF‚ H2CO3‚ H2SO3‚ and NH3.While nonelectrolytes are nonpolar covalent compounds such as O2 and H2O‚ and under acids we

Therefore changes to the shape of an enzyme hinder its ability to recognize its substrate‚ which in turn affects its ability to function. These changes usually occur in the external environment of the enzyme: change in temperature‚ pH level‚ and ionic concentration. When the changes in the environmental conditions are too extreme‚ the enzyme denatures meaning it completely loses its ability to function. The purpose of this experiment was to observe how changes in these external environment factors

Many tertiary proteins such as enzymes depend on various weak ionic bond‚ hydrogen bonds‚ disulfide bridges‚ and hydrophobic interactions(van der

products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when the reacting element is more active‚ whihch means it is more likely to lose electrons than the product element. There was two parts to this experiment‚ in Part A we mixed various aqueous solutions of ionic compounds and observed

1. Why are drugs classified in the categories they are? The term drug class generally refers to the area affected by a drug or its effect on the body (BIO-316V Module 2 Lecture‚ 2012). Many drugs can fit into more than one category‚ but they are usually classified by their therapeutic action. A drug’s therapeutic category refers to its purpose—the diseases or conditions it treats (Drug Classifications‚ 2013). Drugs can also be classified by the chemical type of the active ingredient. 2.

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
