Rubidium forms amalgams with mercury and alloys with gold‚ sodium‚ potassium‚ and cesium. Rubidium glows red-violet in a flame test. Rubidium Trivia: • Rubidium melts just a little above body temperature. • Rubidium was discovered using spectroscopy. When Bunsen and Kirchoff examined their sample of petalite‚ they found two red spectral lines deep into the red part of the spectrum. They named their new element rubidium after the Latin word rubidus meaning ’deepest red’. • Rubidium is the

Amlodipine is a calcium channel blocker that acts on the cardiac muscle and its peripheral vessels. Acting on the myocardial cells‚ which are responsible for the conduction of the electric stimuli of the heart‚ Amlodipine causes a decrease of the myocardial contractility [1]. Amlodipine causes dilation of coronary and peripheral arteries which is an important treatment of hypertension‚ as well as increasing blood flow to the cardiac muscle which aids angina [2].

CHAPTER 1 Introduction and Its Background Introduction Infectious diseases are one of the main contributors to global mortality and morbidity. Infectious diseases are caused by pathogenic microorganisms‚ such as bacteria‚ viruses‚ parasites or fungi. These diseases can be spread‚ directly or indirectly‚ from one person to another. Vaccines‚ antibiotics‚ and many other advances have lessened the impact of infectious diseases. Unfortunately‚ this has not been true everywhere. It has not been true in

briefly explain why you identified each unknown as you did. 3 Unknown 1 was sodium and unknown 2 was potassium. Each element has it’s own color so all I did was match the element’s colors I had already tested with the unknown’s color. Part Two (Spectroscopy): 1 Create and complete a data table for Part Two of the lab. It should include the name of the element‚ the colors‚ and the wavelength values of the observed lines. 1 HydrogenHeliumSodiumNeonMercury1Pinkish-Purple (412nm)Blue (449nm)Yellow (580nm)Purple
