Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

Differences Between Ionic and Covalent Compounds Abstract In chemistry‚ a compound is a substance formed from two or more elements‚ with a fixed ratio determining the composition. A defining characteristic of a compound is that it has a chemical formula. Formulas describe the ratio of numbers of atoms in a substance. Compounds may have a number of possible phases. For a compound to be a liquid or a gas and still be called a compound‚ atoms from the various elements must be stuck together in

Traffic Stream Characteristics Traffic facilities are broadly separated into two principal categories. * Uninterrupted flow * Interrupted flow The major difference between the uninterrupted and interrupted flow facilities is the impact of time. On uninterrupted facilities‚ the physical facility is available to drivers and vehicles all at a time. On a given interrupted flow facility‚ the movement is periodically barred by “signal systems”. The signal timing‚ therefore‚ limits access to

This is “about the self’s over identification with its views and interests‚ which easily leads to a narcissistic denigration of the other and a violation of universal laws” (Wing-chi Ki 25). The narrator is so focused on this man’s problem that he never notices his own. This leads to murder‚ which is against the law everywhere. The link to the bible and the term Ego-Evil shows that there could be several meanings to what Poe writes

I happened to talk to one of my friends in the mess regarding sadness. These are his words. " dukhi hone ka bhi apna alag hi mazaa hai. Khushi to ek phuljhadi ki tarah hoti hai jo thodi der main khatam ho jaati hai‚ par dukh ek agarbatti ki tarah bahut der tak chalta hai" (happiness lasts for a very short time but sadness lasts for a very long time). A line from Eric Erikson’s theory of eight stages of man. " Teething seems to have a prototypal significance and may well be the model for the masochistic

Procedure / Data / Conclusions: Unknown #1: I found solution 1 to be KI. While doing the precipitate reactions‚ I found that it precipitates only with BiCl3 to form BiI3 which is an inorganic compound. The precipitate reaction is shown below: 3KI(aq) + BiCl3(aq) ⇒ 3KCl(aq) + BiI3(s) Since potassium is very soluble and bismuth reacts with iodine‚ I concluded that solution 1 is KI. Unknown #2: I found solutions #2 to be H2SO4. While doing precipitate reactions
