Observing and deciphering Chemical Changes Purpose The purpose of this experiment is to observe reactions of chemicals that can be found in consumer products. Through observation‚ students should be able to interpret the chemical reactions and determine some characteristics‚ such as pH and solubility. Method 1. Pipets containing chemicals will be opened using scissors to snip the end and each pipet will be placed in a well of a 24-well plate. The scissors must be washed between each pipet. 2

as “to the degree to which the individual’s genetic heritage actually serves to predispose the individual to a substance use disorder‚ and how much of this is the result of psychosocial factors” (Doweiko‚ 2012‚ p. 344).

However‚ when we introduce water to big greasy hydrocarbon chains (usually called alkanes‚ or fats and oils as we know them)‚ the water just slides right over them and our plate stays greasy. This is because fats‚ oils‚ and waxes are nonpolar substances. If instead of using water we used less polar mineral spirits
