GRAVIMETRIC DETERMINATION OF SULFATE Purpose You will be given a solid powder‚ which has been dried to constant mass. The sample is water soluble. The purpose of this experiment is to determine the concentration of sulfate in your solid sample using gravimetric analysis. Background Gravimetric Analysis The goal of most quantitative chemical analysis measurements is to estimate the relative abundance of an analyte in a chemical sample. For solid and liquid samples‚ a very common expression

Silver Linings Playbook directed by David O. Russell is based on Pat Solitano‚ a former teacher who was diagnosed with Bipolar 1 Disorder after walking in on his wife cheating with the history teacher from the school they teach at.

OPTIMAL FORAGING PATTERNS IN SILVER GULLS (LARUS NOVAEHOLLANDIAE) ABSTRACT There appears to be different types of foraging behaviour patterns that are shown by different species throughout the world. These different patterns affect the amount of food gained by the individual as well as the amount of food gained by others in that species. In this study the silver gull’s (Larus novaehollandiae) forging patterns were studied‚ to determine what‚ if any‚ foraging strategies they engaged in. Three
