Hydrate Isomerism

Q. assertion equivalent weiggt of NH3 in the rxn N2-NH3 is 17/3 while that of N2 is 28/6 how this eq weight identified

Q. 28 kg of N2 and 3 kg of H2 are mixed to produce NH3. The maximum amount of NH3 formed is.

Q. One of the most important properties of `d`-block metal cations is the formation of coordinate compounds. Widely used theories that explain bonding in these compounds are valence bond theory and crystal field theory.
The incorrect option for the complex compounds $\left[Co\left(SCN\right){\left(H_{2}O\right)}_5\right]{\left(N{O}_3\right)}_2\text{and}\left[Co\left(N{O}_3\right){\left(H_{2}O\right)}_5\right]\left(SCN\right)\left(N{O}_3\right)$ is:

1. Both are ionization isomers
2. They can exhibit hydrate isomerism
3. They can exhibit linkage isomerism
4. They do not show stereoisomerism
