How many resonance forms can be written for the nitrate ion,$(NO_3^-)$?

What is the reason for the two carbon-oxygen bonds in the $HCOO^-$ anion having equal length?

Identify the correct statement.

What are the resonance structures and shape of $N_2O$?

In graphite, the $C-C$ bond length $(141.5 \, pm)$ is found to be shorter than the normal $C-C$ single bond length $(154 \, pm)$. This anomaly occurs due to:

The formal charge on the $O$ atom and the $P-O$ bond order in the $PO_4^{3-}$ ion are,respectively,.......
