For a face centered cubic lattice, the Miller indices for the first Bragg's peak (smallest Bragg angle) are

For the titration of a 10 mL (aq) solution of $CaC{O}_3$, 2 mL of 0.001 M $N{a}_{2}EDTA$ is required to reach the end point. The concentration of $CaC{O}_3$ (assume molecular weight of $CaC{O}_3=100$) is

In the reaction



the product formed is

In the reaction given below, identify the product

Consider the following pairs of complexes

$[CoF(N{H}_3{)}_5{]}^{2+}$ and $[Cr(O{H}_2{)}_6{]}^{2+}$

$[Co(N{H}_3{)}_5(O{H}_2){]}^{3+}$ and $[Cr(O{H}_2{)}_6{]}^{2+}$

$[Co(N{H}_3{)}_6{]}^{3+}$ and $[Cr(O{H}_2{)}_6{]}^{2+}$

$[Co(N{H}_3{)}_5{]}^{2+}$ and $[Cr(O{H}_2{)}_6{]}^{2+}$

The electron transfer rate will be fastest in the pair
