Why is work positive in an exothermic reaction?
kind of depends on the reaction. ex. solid and a liquid react causing a an aqueous solution and a gas to form. when a gas is formed the gas expands causing it to do work on its surroundings causing work to be negative.
What is the symbol for solution in water in a chemical reaction?
(aq) aqueous.
Why do biologist use solutions that are 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.
An insoluble substance produced by a reaction in aqueous solution is called an aqueous solid?
It is more likely to be called a precipitate.
Does an aqueous solution of CaNO32 and tin metal react?
A reaction doesn't occur.
Why is there a temperature changes when alkali is added to vinegar?
When an alkali (base) is added to vinegar, the acetic acid in the vinegar reacts with the alkali. These reactions are nearly all exothermic, that is, they generate heat as the chemical reaction proceeds. This is observed by a change in the temperature of the aqueous solution and the surrounding air.
When an aqueous solution of lithium chloride is mixed with an aqueous solution of ammonium sulfate what happens?
No reaction occurs

When aqueous solutions of potassium fluoride and nitric acid are mixed an aqueous solution of potassium nitrate and hydrofluoric acid results Wirte the net ionic equation for the reaction?
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.

What happens to ions in an aqueous solution?
Double Replacement
What is the solution process with water as the solvent?
This solution is called water solution or aqueous solution.
What is the chemical reaction when a silver spoon is kept immersed in aqueous cooper sulphate solution?
Any reaction occur.
What is the balanced chemical equation for the reaction of aqueous calcium chloride with aqueous sodium carbonate to produce calcium carbonate precipitate in an aqueous sodium chloride solution?
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
