Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

and were soon to be forgotten. As we learn from the book he categorizes the truth in two ways (happening truth and story truth)‚ leaving us realizing that the truth is only how you see it. Telling a story in first person can be reliable. This is why the narrator writes these war stories mostly in third people because he wants us to believe him.

to believe truth is relative; but that statement in and of itself is relative. We confuse knowledge with truth. Before the heliocentric theory‚ it was considered truth that the universe orbited the earth. The common knowledge of that day altered their truth. Our generation considers the statement "love is love" as truth. Yet‚ this same statement considered the highest of sins less than a few decades ago. Our society has made us believe truth is relative so we could all coexist. If truth is relative
