In making gun-berrel, the steel used is
$Fe - Mn$
$Fe - Cr$
$Fe - W$
$Ni - Mo$
When $Cu^{2+}$ ion is treated with $KI$, a white precipitate is formed. Explain the reaction with the help of chemical equation.
Although $Cr^{3+}$ and $Co^{2+}$ ions have same number of unpaired electrons but the magnetic moment of $Cr^{3+}$ is $3.87\,BM$. and that of $Co^{2+}$ is $4.87\,BM$. Why ?
Explain trends in $M^{2+}/M$ standard electrode potentials.
Which of the following order is correct
Which of the following graph is correct representation between atomic number $(Z)$ and magnetic moment of $d-block$ elements? [Outer electronic configuration : $(n -1)d^x\, ns^{1\, or \,2}$]
