every pure substance has a characteristic physical properties that can be used to identify it. The blocks in the toolbar are either silver, tungsten or platinum. use the tools in the simulation to identify the type of metal in each block in the toolbar. you can assume all the blocks are perfect cubes.

Which element has the lowest electronegativity? calcium(ca) gallium(ga) selenium(se) bromine(br)

Quiz1. which physical state of nitrogen has the highest entropy? a solid© b gasoc liquid

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
