To be able to answer this, you need to have a phase diagram of Cu-Ni alloy. Create a vertical line along 40% in the x-axis. Then, create a horizontal line along the temperature at 1,300°C. The intersection lies outside of the α-L boundary.
<em>Therefore, the system consist solely of the L-phase: 100% L.</em>
<u><em>Answer:</em></u>
It was a positive ion.
<u><em>Explanation</em></u>
In CaBr, ionic bond is present. When one of the atom loses electrons and gets positive charges and other atom gains electrons and become negative. As a result of positive and nagative charges , a ionic bond formed.
As in this case, Ca loses electrons and become positive ion while on the other hand bromide gets the electrons and become negative ion.
<em>Note:</em>
Electropositive atoms always loose electrons Like Ca while electronegative atoms always gain elelctrons like Br.
A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.
In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula 
where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula 
to chlorine which gains electron and thus results in an anion formation having formula 
. The force of attraction between these oppositely charged ions that helds them together and results in formation of compound is electrostatic force of attraction.
Hence in salt, the nature of bond between sodium and chlorine is ionic.
