Environmental Effect from the Gold Rush Every tribe‚ city and nation has its own story that gives it a defining trait and our state of California is no different. Most people know that California is also known as the “Golden State”‚ but among all the reasons that gave it this name‚ aside from the unlimited sunshine throughout the year‚ the Gold Rush back in the mid 19th century is probably the most significant one of all. Most would agree that the Gold Rush was a positive‚ iconic event in California’s

Pollution and its types The term pollution refers to the act of contaminating ones environment by introducing certain hazardous contaminants that disturb the ecosystem and directly or indirectly affect the living organisms of that ecosystem. Pollution in general is the activity of disturbing the natural system and balance of an environment. The increase in the pollution over the years by man has caused severe damage to the earth’s ecosystem. It is responsible for global warming which is leading

Environmental Effects of the Bottled Water Industry Environmental Science Environmental Effects of the Bottled Water Industry I myself am a firm believer in drinking only bottled water under the belief that it is safer‚ cleaner‚ and better tasting. I also believed that the bottled water industry couldn’t be polluting the environment. After all how could something so natural be bad for the environment? In the research that follows I will explain just how wrong I really was in my beliefs

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Global is good 1. Of or relating to the whole world; worldwide: "global economy". 2. Of or relating to the entire earth as a planet: "global environmental change". Global warming is bad. It has been enhanced by us humans… One of the consequences is‚ in 2075 67% of Americans are expected to be born with skin cancer. 45% of those Americans born with skin cancer will die. This is caused by ozone depletion. This is sad but true… Resolution: Save energy-don’t use so much electricity‚ STOP

Four environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic

September 2011 ISOTOPES Atoms of a given element which have the same number of protons but different numbers of neutrons are called isotopes. Thus‚ isotopes have the same position in the periodic table‚ the same chemical properties and the same atomic charge. The simplest example of an atom with different isotopes is hydrogen. The three isotopes of hydrogen are shown here: The increasing number of neutrons in the nucleus of the hydrogen atom adds mass to the atom and thus each isotope of a given

The Atomic Mass of Metallo You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however‚ they are just a little different from every other atom of the same element. Most of the carbon atoms in the universe are Carbon-12‚ with 6 neutrons. A small percentage of carbon atoms are Carbon-13‚ with 7 neutrons

Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

President Harry S. Truman‚ atomic bombs were dropped on Hiroshima‚ and Nagasaki‚ marking the only time nuclear weapons were used in warfare in all of U.S. history. It roughly killed about 129‚000-246‚000 or more people. Using a weapon of such untold destructive force‚ it made Japan finally announced its surrender to the Allies. Was America justified in dropping the atomic bomb on Japan? I think that America was justified in dropping the atomic bomb on Japan. Dropping the atomic bombs on Hiroshima and Nagasaki
