We are going to measure the amount of gaseous product obtained from the amount of gaseous product obtained from reaction. Then compare to theoretical yield‚ Percent Yield=Actual Yield of Gas/ Theoretical Yield of Gas×100‚ based on stoichiometric

Air pollution has been around on earth for a long time. Most of the air pollution that is on the earth is made by humans everyday‚ but it is not just our fault either. Some of the air pollution is made naturally. Air pollution is caused by to much of gases‚ very fine particles‚ and some liquids. As easily as it is to make the pollution‚ it is hard staying away from the harmful effects of it and also to quit polluting the air. Air pollution is caused by many of the things that we depend on for

WHAT IS HARM REDUCTION? Harm reduction is a set of practical strategies intended to reduce the negative consequences of high risk behavior such as over drinking or drug abuse. Harm reduction is a non judgmental approach that attempts to meet people where they are at with their drinking or drug abuse. Instead of demanding perfect abstinence‚ this pragmatic approach is supportive of anyone who wishes to minimize the harm associated with a high risk behavior such as drinking or drug abuse. Harm

for their dangerously high levels of air pollution and the resulting health issues‚ such as asthma and emphysema. Summer heat and vehicle emissions are just a few of the contributing factors that increase air pollution levels. However‚ healthy trees planted effectively along roads‚ buildings and in parking lots can decrease overall air pollution levels for city residents.Trees can remove both gaseous air pollutants and particulate matter. Gaseous air pollution enters a tree through leaf stomata and

Coal – Energy Where are coal reserves? Surface mining and deep underground mining are the two basic methods of mining. Many coals extracted from both surface and underground mines require washing in a coal preparation plant. Coal Exploration - Coal reserves are discovered through exploration activities. The process usually involves creating a geological map of the area‚ then carrying out geochemical and geophysical surveys‚ followed by exploration drilling. This allows an accurate picture of

An unnatural coal disaster is one caused by human error or negligence‚ there have been many unnatural coal disasters from past to present such as Turtle Mountain in Canada .Normal erosion due to weather changes played a part in this unnatural disaster but the biggest factor was inadequate support beams .which in turn caused gigantic slab of limestone rock weighing 75millions

Pollution Human beings have always caused some environmental pollution. Since prehistoric times‚ people have created waste. Like garbage today‚ this waste was either burned‚ tossed into waterways‚ buried‚ or dumped aboveground. However‚ the waste of early peoples was mostly food scraps and other substances that broke down easily by natural decay processes. Prehistoric populations were also much smaller and were spread out over large areas. As a result‚ pollution was less concentrated and caused

WHAT IS ENVIRONMENT POLLUTION? The most appropriate definition of environmental pollution would be the introduction of different harmful pollutants into certain environment that make this environment unhealthy to live in. The most common pollutants are usually chemicals‚ garbage‚ and waste water. Environmental pollution is happening in many parts of the world‚ especially in form of air and water pollution. The best example for air pollution are some of China ’s cities‚ including capital Beijing

Introduction to Adit Mining Adit mining is a method of extract minerals from earth horizontally. An adit is a type of entrance to an underground mine which is horizontal or nearly horizontal. Adits are usually built into the side of a hill or Mountain‚ and often occur when a measure of coal or an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface‚ the adit may follow the vein until it is worked
