Utilizing a thermometer to measure the temperature change of the solution can be used (along with the mass of the reactant(s)) to determine the enthalpy change for an aqueous reaction, as long as the reaction is carried out in a calorimeter or similar apparatus so that no external heat is added or removed from the system.
(aq) aqueous.
biologist used aqueous solution to perform chemical test as this solution behaves as the medium for chemical reaction and is also the medium of chemical reaction in living beings so that is why biologist use aqueous solution.
It is more likely to be called a precipitate.
A reaction doesn't occur.
Double Replacement
No reaction occurs

When aqueous solutions of potassiumfluoride and hydrobromic acid are mixed, an aqueous solution of potassiumbromide and hydrofluoric acidresults. Write the net ionic equation for the reaction.
A reaction doesn't occur.

This solution is called water solution or aqueous solution.
Any reaction occur.
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
