Combustible Liquid - Correct answer-A liquid with a flash point ABOVE 100F 12.5 - Correct answer-If the current flowing out from an electrical panel is 12.5 amps, and it then flows through an electrical load of 1500 watts, what is the amperage of the remaining current flow of the return circuit? 1000 - Correct answer-If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage? *Power (P) = current (I) x voltage (V) Watts = amps x volts 1987 - Correct answer-The y...

Title: Bonding Type by Solubility, Distillation, and Spectroscopy Purpose: In this lab, we will study the bonds that form between molecules. We learn about the Infrared Spectra and physical properties of molecules to determine what kinds of intramolecular bonds are present within the molecules and what kinds of inter-molecular bonds are present between the molecules. Procedure: There are several different types of bonds – Hydrogen bonds, Polar bonds, and Nonpolar substances that form ver...
