Answer :
Hg2(NO3)2 NaBr will precipitate when combined in an aqueous solution without a catalyst at room temperature.
What is an aqueous solution?
A solution that uses water as the solvent is said to be aqueous. It is frequently represented in chemical equations by adding to the relevant chemical formula.
To represent a solution of table salt, or sodium chloride, in water, the symbol Na+ + Cl can be used.
In an aqueous solution, liquid water acts as the solvent.
In other words, the ions and molecules that make up the solute (dissolved) are surrounded by the water molecules and incorporated into their web of connections.
The dissolved organisms then spread out across the water.
An aqueous solution is, to put it simply, anything that has dissolved in water.
The water sign represents (aq).
A substance that has been dissolved in water is called an aqueous solution.
Therefore, Hg2(NO3)2 NaBr will precipitate when combined in an aqueous solution without a catalyst at room temperature.
