Are we living in a post-racial society? Do we want to be? Is it possible? Is this question ridiculous? Why are people so obsessed with race? What does President Obama‚ the media’s perception and portrayal of him and his various racial attributes‚ native Americans‚ the media’s perception and portrayal of them‚ sports‚ perception of racial issues as white/black versus Arab/Hispanic/Asian‚ and Attorney General Holder say about our society and it’s relation with race? To many a post racial society is

Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

How reaction rate varies with sodium thiosulphate concentration Background information Sodium thiosulphate and hydrochloric acid are both colourless liquids‚ when the two reactants are reacted together they produce sulphur. The sulphur that is produced from the reaction changes the solution to yellow and cloudy‚ this is a precipitation reaction‚ where a two solutions react and a solid forms in the solution‚ the solid is said to precipitate out. Some reactions will occur quickly such as fireworks

Introduction: The purpose of this lab was to separate and purify a compound. This was achieved using techniques that allowed the extraction of the acid‚ the isolation of the neutral compound and the melting point classification of the neutral compound to test the purity of the sample. Chemical Reactions: HA + OH- A- + H2O R-COOH + OH- R-COO- + H2O Organic Acid Insoluble in H2O Conjugate base Soluble in H2O Procedure: A 0.170g sample consisting of a mixture of 0.110g

becomes irrelevant. The question is if truth has become so twisted that it doesn’t really exist in its original meaning anymore? If truth has been lost there must be a substitute‚ this is where post-truth originated. Post-truth is when decisions are based upon emotions rather than facts‚ this is dangerous because each person feels a different way and therefore can justify melding a subject to fit their own liking. Post-truth has caused all truths to be called into question because emotions open up
