(5). a) What are sheet-molding compounds (SMC)? Bulk-molding compounds (BMC)? Sheet-molding compound (SMC) is a fiber glass reinforced thermosetting compound in sheet form‚ usually rolled into coils interleaved with plastic film to prevent auto adhesion. Made by dispensing mixed resin‚ fillers‚ maturation agent‚ catalyst and mold release agent onto two moving sheets of polyethylene film. The lower one also contains chopped glass roving or glass mat. SMC can be molded into complex shapes

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

Mrs. Feeney Biology 9 October 16‚ 2012 Identifying Organic Compounds Objective: To use indicators to test for the presence of organic compounds in certain substances. Theory: Major types of organic compounds in some common foods are Lipids‚ Carbohydrates‚ and Proteins. An indicator is a chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test
