rain is caused by the numerous acidic pollutants‚ which have potential to damage earth’s environment in a drastic way. Acid rain is caused due to the presence of chemicals like Sulfur Dioxide and Nitrogen Oxides in the atmosphere. These chemicals are introduced in the atmosphere as a result of the industrial processes. Sulfur Dioxide is emitted out of those industries that use coal as

Hazardous Chemical Mustard Gas Imagine sitting in a trench during World War 1 with your fellow soldiers and someone shouts‚ “Incoming!” you duck deeper into the trench and fumble for your helmet‚ not realizing that it could be your last seconds on this earth. Instead you smell a pungent mustard aroma‚ struggling to breath‚ it subsides after a couple of minutes. Without knowing it you have been exposed to a new chemical used by the Germans‚ code named LOST‚ which referred to the last names of the

Persuasive Speech Alternative Fuels for Diesel 11/30/06 8:00 AM To persuade listeners to support alternative fuels The strain on the diesel supply in America is too high and a stable source must be found to alleviate the strain. Bio-diesel is a suitable additive in diesel that would help reduce this strain. Bio-diesel is also much safer than conventional petrol-diesel. Topic: Alternative Fuels for Diesel Speaker ’s Goal: To persuade listeners to support alternative

driven up to shallower depths in the crust. The subducting tectonic activity helps drive this process with ground water acting on the copper solution from convective circulation creating a porphyry deposit. The ore solution must contain metal and sulfur in molecular species in concentrations sufficient enough to form a porphyry copper deposit (Bowen and Gunatilaka‚

We breathe it and burn fuels in it. Plants use it to grow. It is all around us but we hardly notice it except when the wind blows. Aircraft and birds fly in it. More than one hundred kilometres above us‚ satellites look down through it. In the apparatus shown here‚ air is passed from one syringe to the other while the copper in the tube is heated. The oxygen from the air joins with the copper‚ so the volume of the air gets smaller. The amount of oxygen in the air is the difference in

These air pollutants are mainly from man made resources such as factories and automobiles. The burning of fossil fuels is also one of the biggest factors that pollutes the air and causes acid rain. The primary emissions from man made resources are sulfur dioxide and nitrogen oxides. The rain actually becomes acidic when the water molecules in the air mix with these acidic chemical pollutants and forms an acid substance. This then falls as acid rain. Acid rain can also be formed by blowing acidic chemicals

mixture of reducing agents and to excite the atoms of the light-emitting compounds. Various oxidizers are used in both the black powder and the stars. The most commonly used oxidizers are nitrates‚ chlorates‚ and perchlorates. The reducing agents‚ sulfur and carbon‚ combine with the oxygen from the oxidizers to produce the energy of the explosion.

This sulfur gets mixed with moisture and thus irritates your eyes. 6) You feel hungry because of the satiety center in your brain falls short of particular hormones to function and then sends the signal of hunger. 7)
