When solid mercury(ii) nitrate is heated, it decomposes to form solid mercury(ii) oxide, gaseous nitrogen dioxide, and oxygen?

Decomposition reaction is a type of reaction where it involves a single compound breaking down into two or more products. These reactions often requires an energy source thus it is an endothermic reaction. This is evident for this reaction since we supplied heat to the reactant for the reaction to proceed.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
