Freezing point of lawrencium
WebThe flash point, autoignition temperature, and heat of combustion of Acetonitrile are listed in Table 2.1. The flash points of several Acetonitrile-Water mixtures have been determined. The results are shown in Figure 2.8. Vapor mixtures of Acetonitrile and air containing between 4.4 and 16 percent Acetonitrile at 25°C are potentially flammable. Lawrencium is a synthetic chemical element with the symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranic element and the last member of the actinide series. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding light…
