Copper and Nickel form a substitutional solid solution over the complete range of possible compositions of the alloy. The equilibrium "phase diagram" opposite shows the dependence of the alloys ...

and chilling until the mixture freezes and forms solid crystals. To then discover the melting point of the newly formed acetaldehyde phenylhydrazone, you have to re-melt it. This is where the ...

All substances will change state at specific temperatures, known as their melting and boiling points. Many substances can exist as solids, liquids or gases, which are all different states of matter.

In the solid state it forms an fcc crystal with a melting point of -189.4 C and a boiling point of - 185.8 C. The electronic configuration of Argon is (Ne)(3s 2)(3p 6). Its atomic radius is 0.098 nm.
