Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is

Could Hitler have been stopped? Here are three ways how Hitler could have been stopped like childhood dream ruined‚ being killed in World war one‚ and another country stopping the holocaust. During World war one a British soldier saw a wounded Hitler‚ and refused to shoot him because he said: “I can’t shoot a wounded man.” If the man shoots twenty-year-old Hitler this world would have been a different place. When Hitler a young boy he wanted to be an artist‚ but the academy that he went to rejected

Experiment 11.1 Conversion of t-Amyl Alcohol to t-Amyl Chloride Using HCL October 27‚ 2011 Purpose: Alkyl halides can be prepared from alcohols by reacting them with a hydrogen halide‚ HX (X = Cl‚ Br‚ or I). The mechanisms of acid-catalyzed substitution of alcohols are termed SN1 and SN2. The “S” stands for substitution‚ the “N” stands for nucleophilic‚ and the “1” or “2” stand for unimolecular or bimolecular. Secondary alcohols react with hydrogen halides by both SN1 and SN2

What could they be seeing under the sea. What was this monstrous animal. Could it be a squid‚ a submarine‚ a giant whale? Let us go down in the deep waters of the earth and see which one it is. “If it was a whale‚ it surpassed in size all those hitherto classified in science.” (the book) Could this animal be a giant squid? “Taking into consideration the mean of observations made at diver’s times- rejecting the timid estimate of those who assigned to this object a length of two hundred feet‚ equally

A Roman Catholic would forbid all forms of active euthanasia and most forms of passive euthanasia. This is because any act that intentionally brings about death is considered murder also euthanasia is not permitted due to your life being a gift from God and only God decides when your death comes‚ the sanctity of life. Ordinary treatments such as food and water must continue but extraordinary treatments such as complicated operations can be withdrawn. Although Roman Catholics do not allow euthanasia

battles were fought‚ but all had a consequence. Some consequences still last till this day in the year 2017. Although most of them have died down throughout the years‚ several never left. Each factor in the war had a tremendous impact on the future and most consequences could have been stopped. Over 60 million people were killed in World War II and several of these deaths could have been prevented. The entire war could have been prevented if Adolf Hitler did not violate The Treaty of Versailles. If France
