carbon-oxygen compounds existed‚ we could predict small‚ whole-number ratios for the masses of oxygen per gram of carbon in all of them. This is exactly what John Dalton predicted for compounds using his atomic theory of matter. It came to be known as the law of multiple proportions. Part A There are two different compounds of sulfur and fluorine. * In ‚ the mass of fluorine per gram of sulfur is 3.55 . * In the other compound‚ ‚ the mass of fluorine per gram of sulfur is 1.18 .

DETERMINATION OF THE MOLAR VOLUME OF A GAS AND THE UNIVERSAL GAS CONSTANT Salve‚ Ryan Angelo TAB3‚ Group 6‚ Mr. John Kevin Paulo Biadomang Tabor‚ Frances Hermilyn March 8‚ 2013 ------------------------------------------------- I. Abstract This experiment is working with the ideal gas law‚ which is the summation of Boyle’s Law‚ where pressure is inversely proportional to volume‚ Charles’ Law‚ where the volume is directly proportional to temperature and Avogadro’s Law‚ where the volume is directly proportional

Gas Exchange The process of gas exchange in the body is called respiration. This process has three basic steps that involve pulmonary ventilation‚ external respiration‚ and internal respiration. All three steps are functions that involve gas exchanges between the lungs and the atmosphere. For instance‚ pulmonary ventilation‚ or breathing involves the inhalation and exhalation of air between our lungs and the atmosphere. External respiration is the exchange of gases across the respiratory membrane

“People saw enemies everywhere‚ enemies who wanted to destroy the revolution and diminish the results of their hard work &accomplishments‚ and this only increased tension within society”. The purges deceived the general public and spread paranoia amongst the people‚ who thought the ideals of the revolution for which they had fought so hard‚ would collapse if they did not support Stalin. This directly resulted in the damage of morale and unity in the Soviet Society. For the remaining population‚ a

II Unit 5 Gas Exchange Explain how the gas laws and the properties of gases affect the gas exchange between the lung‚ blood‚ and tissues. The major function of the respiratory system is to provide the body with oxygen and rid the body of carbon dioxide. Gas exchange occurs between blood and alveolar air (external respiration) and between blood and tissues (internal respiration).Gas exchange process depends on properties of gasses. Based upon the Basic properties of Gases; Dalton’s Law states that

Mustard Gas During World War I LOST was the original name for mustard gas‚ it was named after Lommel and Steinkopf. They were the first people who proposed this gas to the military to use as a weapon in 1916. Although mustard gas could possibly been developed as early as 1822 by a French chemist‚ Cesar-Mansuete Desperetez. Thirty-two years later Alfred Riche repeated this reaction of the sulfur dichloride and ethylene‚ but both Riche and Desperetez did not note any harsh properties. In 1860‚
