Higher Chemistry Mole Calculations Moles and Number 1 mole of any substance contains the same number of atoms/molecules/ions as there are atoms in a 12g sample of carbon -12 12g of carbon-12 contains a constant number of atoms. This number is known as the Avogadro constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains

9 specific areas year-round‚ and wintertime only months in 39 more areas. 2. What is winter oxygenated fuel and what is the benefit to the environment? Oxygenates are added to gasoline in order to reduce carbon monoxide‚ which can indirectly affect global warming. Carbon Monoxide does this by reacting with hydroxyl in the atmosphere. In 1988‚ Denver‚ Colorado was the first place to mandate oxygenated fuels be used during winter months. Adding oxygenates does however reduce the energy density

John Tso Professor: Matthew Ryckebusch Navitas 101 Assignment #3 Word count: 925 The Benefits of Hybrid Cars There was once a time when you could turn on the news and not hear about the terrible state of the environment or the impending doom that is global warming. That time has become part of the past. The standard automobile can be blamed for a large portion of the conflict. Today’s large gasoline engines spew harmful emissions into the air every time we drive. Of course as a result‚ the

Global Warming: Fact or Fiction American Intercontinental University January 13‚ 2013 Unit 1 Individual Project Abstract In this paper I will be discussing the advantages on why we should support the protection of Global Warming. Now yes there are disadvantages as well. But the only ones that are suffering are the big industrial companies and commercial auto transport makers. If you step back and look at the big picture it really will out weight all outs.

Environmental Fundamentals Laura Jackson Env/100 April 8‚ 2013 JOHN ENSWORTH Environmental Fundamentals Introduction Environmental science is defined as the study of the environment and the interconnecting systems it contains‚ furthermore‚ the way people interact with their natural surroundings and use natural resources (wise geek‚ 2013). Scientist in this field is highly interdisciplinary and extremely diverse‚ for example‚ a scientist might study volcanoes or climate change. This essay

liquid droplets‚ or gases. In addition‚ they may be natural or man-made.[2] Pollutants can be classified as primary or secondary. Usually‚ primary pollutants are directly emitted from a process‚ such as ash from a volcanic eruption‚ the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather‚ they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground

If it have these two features : It diffuse across alveolar capillary membrane It binds with hemoglobin. Why we use CO in this test instead of other gases? Because of two factors: Carbon monoxide diffuse very rapidly across the alveolar-capillary membrane. So‚ there will not be a back pressure. Carbon monoxide has high affinity 230 times

Transportation is the largest single source of air pollution Today’s on-road vehicles produce over a third of the carbon monoxide and nitrogen oxides in our atmosphere and over twenty percent of the global warming pollution. This air pollution carries significant risks for human health and the environment. Through clean vehicle and fuel technologies‚ we can significantly reduce air pollution from our cars and trucks‚ while cutting projected U.S. oil use in half within the next 20 years. Cars and
