pays to a lender for use of its money is interest. The annual percentage rate (APR) makes assumptions based on simple interest‚ which is interest only earned on the principal investment. Another method of accruing interest is through compounding. Compound interest is not only charged on the original investment‚ but also assessed on the interest charged or earned for each period. "When comparing interest rates‚ it is best to use effective annual rates. This compares interest paid or received over a

Fungal contribution in the etiology of infections has increased considerably. However‚ as medical technology has improved‚ The number of infections by intrinsically drug-resistant species has increased rapidly. Despite the constant introduction of new and effective synthetic drugs to the market‚ medicinal plants‚ which are the historical basis of therapeutic health care‚ represent an alternative that is economical‚ accessible‚ and applicable to various pathologies‚ particularly in developing countries

Water and Sodium Chloride were compounds given they are two or more elements‚ while mixing them we were able to create a solution. The Nacl that dissolves into H20 are techinically dissociated into ions but after heating it the table salt comes back without H20. Introduction Matter is anything that occupies space and has a mass. It can be classified into elements‚ compounds and mixtures. Pure substances are divided into categories as elements and compounds. Elements cannot be divided into

Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles‚ or atoms‚ atoms are always invisible and indestructible‚ all atoms of a given element are identical in mass and properties‚ compounds are formed by a combination of two or more different kinds of atoms‚ and a chemical reaction is a rearrangement of atoms. John Dalton was born on September 6‚ 1766 in Eaglesfield‚ England‚ UK to a Quaker family. He had two surviving siblings‚

Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield benzoin. Thiamine catalyst along with water and

Why is organic chemistry important? Organic compounds are used for many different things. Daily life in today’s world would be very hard to live in without organic compounds; in fact life would not be possible without organic compounds. For example‚ most of your body is made up of organic compounds. The food you eat is made up of organic compounds. Even the flavourings and colourings on processed food are organic. The clothes you wear are‚ yes you guessed it‚ organic as well. What’s more is that

than if one had the full amount in hand now to invest. The reason for this is opportunity cost. If the full amount of the annuity could be invested today in a lump sum‚ the final value during the same term of the annuity would be much higher due to compound interest. So opportunity cost in this case is the total amount of the annuity payments over the length of the annuity and the value of investing the annuity ’s total value today at a specified rate of return. For example‚ person is receiving annuity

A Compound Life Sugar Cane Alley was filmed during the summer of 1931 in Martinique a time after the abolishment of slavery. This film parallels a time in Southern Rhodesia where there was a compound system that controlled the mining workers just as the overseers in the cane fields controlled the cane workers. Every aspect of daily life is in some way controlled. Sugar Cane Alley is an insightful film that shows how no matter your environment‚ if you want to succeed you can with a lot of hard work

When elements combine to produce a compound‚ each element is assigned an “apparent” charge. This apparent charge‚ the charge an atom would have if both electrons in each bond were assigned to the more electronegative element‚ may be positive or negative. It is called the oxidation number or state of the element in the compound. Oxidation numbers are very useful in keeping track of what happens to electrons when various elements combine to form compounds. By remembering a few generalizations
