Answer:
a. Change of state
Explanation:
Because you will see that the state has changed
No it stays the same the only thing that changes are the number of electrons
Solution:[tex]Let the molar mass of metal M is 'a',\\
\rn(so)\\
\frac{M_{o}}{2M_{H}+2M_{o}+a} =\frac{2.16}{2.1+2.16+a} =0.328\\
By simple algebric calculation. We get,\\ a=63.56g/mol\\
\rn(Now,)\\
We have to confirm which metal has the molar mass of 63.56g/mol. By using periodic table we have to find it the we get it is Copper(Cu).
