If spin only magnetic moment of $VCl_X$ is $1.73\,BM$ then correct formula is
$VCl_2$
$VCl_3$
$VCl_4$
$VCl_5$
Solid $CuSO_4·5H_2O$ having covalent, ionic as well as co-ordinate bonds. Copper atom/ion forms ................. co-ordinate bonds with water.
Mark the variety of iron which has highest melting point
In which of the following pairs are both the ions coloured in aqueous solution ?
(At. no. : $Sc = 21, Ti = 22, Ni = 28,$$ Cu = 29, Co = 27$)
$E^o$ of $Cu$ is $+0.34\,V$ while that of $ Zn$ is $-\,0.76\,V$. Explain
The melting point of $Zn$ is lower as compared to those of the other element of $3d$ series because
