Bradbury’s Predictions of the Future “Sometimes writers write about a world that does not yet exist. We do it for a hundred reasons. (Because it’s good to look forward‚ not back. Because we need to illuminate a path we hope or we fear humanity will take. Because the world of the future seems more enticing or more interesting than the world of today. Because we need to warn you. To encourage. To examine. To imagine.) The reasons for writing about the day after tomorrow‚ and all the tomorrows that

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

Marcella Efendy Future prediction Future Predictions: China’s Economy Growing to $123 Trillion‚ or Three Times America’s by 2040‚ as the Chinese population over 65 triples in number. A few reasons to think China will become a super power. China’s economy: $123 trillion‚ 3 times America’s by 2040 per capita income will hit $85‚000‚ more than double the forecast for the European Union … China’s share of global GDP— 40% — will dwarf that of the United States (14%) and the EU (5%) 30 years from

<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared

I. Purpose The purpose of this lab is to determine the molecular mass of a volatile liquid. II. Procedure • Place a cork with a small hole in it inside of a test tube and find the weight of the two together using a sensitive balance. • Pour 0.5 mL of the unknown volatile liquid into the test tube‚ insert the cork‚ and place the tube into boiling hot water while keeping the cork above water level. As the gas evaporates‚ excess gas will be released throughout the whole in the cork. Keep the test

Many truly healthy foods are actually broken down to sugar in the body – through the conversion of long and complex sugars called polysaccharides into short and simple sugars called monosaccharides‚ such as glucose. In additions to the breakdown products of fat and protein‚ glucose is a great energy source for
