Lauriaenne Lamb Sconce and her husband, Jerry, former operators of the Lamb Funeral Home in Pasadena, CA, were arrested in 1987 with their son, David, after investigators alleged that they had mishandled human remains. Sconce attorney told jurors that mass cremations, commingling of ashes, and dental gold and other body part extractions did take place at the third generation family business. But these acts were done by their son, David, without their permission or knowledge. The Deputy District Attorney alleges David did not engage in the illegal activity alone.…
B: rankings of the unknown liquids from strongest (1) to weakest (5). Based on the T values found, the highest temperature decrease will have the weakest intermolecular forces and vice versa.…
Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors, produce gases proving if the solutions are soluble or insoluble.…
