Amoxicillin Amoxicillin is a penicillin antibiotic. It fights bacteria in your body. Amoxicillin is used to treat many different types of infections caused by bacteria‚ such as ear infections‚ bladder infections‚ pneumonia‚ gonorrhea‚ and E. coli or salmonella infection. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer

INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

.Experiment for Chemistry Coursework For this investigation I am looking at how the concentration of acid can change the reaction and how I can explain this using collision theory. My Prediction: I predict that the greater amount of concentration the faster the reaction will take place. Therefore‚ particles in the two compounds will collide faster. Due to my prediction if it is correct‚ I expect to see the cross on the paper disappear faster. As I already know that increasing one quantity

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the
