Cutting up the Na is the right way to do it, that the Na should melt is strange though, the m.p. of sodium is above the b.p. of THF... Maybe it stuck to the glass, that might explain why it would melt. Gloominati • 11 yr. ago

WebDensity is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance. Note: We are purposely using the terms “size” and ... WebMar 24, 2024 · We also say, in the beginning chemistry course, that all nitrates are soluble, so ammonium nitrate is soluble on both counts. As the water evaporates, you get to the solubility limit of ammonium nitrate. Then, with further evaporation, solid ammonium nitrate is formed, unless the solution is becomes supersaturated. ...
