ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing purposes and Bunsen burner‚ clay triangle‚ crucible

eggshells and dryer lint. What we DO NOT want to compost is dairy products‚ meat scraps‚ animal fats‚ bones‚ dog and cat feces and diseased plants or fruits. These materials may attract dogs‚ rats or other animals. They may also develop an unpleasant odor during decomposition Weed plants heavily laden with seeds might be better left out of the compost pile if the compost is to be returned to the garden. Even though some seeds are killed during composting‚ there is the chance that some seeds will survive

Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

Fleas are very small insects. They are all flightless and do not have eyes‚ although two ocelli may be present. Their antennaes are short and their mouthparts are adapted for piercing and sucking. The female flea lays a few eggs daily that total up to 300 to 400 in its lifetime. The eggs are laid usually on animals and most drop off where they spend most of their time. Bedding‚ floor crevices‚ carpeting‚ along baseboards and areas near their favorite sleeping and napping sites are especially likely
