What can be said of a closed system when an exothermic reaction proceeds in an aqueous solution?
In a closed system, when an exothermic reaction occurs in an aqueous solution, the reaction releases heat into the surroundings, resulting in an increase in the temperature of the solution. This release of energy can affect the solubility of reactants and products, potentially shifting the equilibrium position if the reaction is reversible. Additionally, the increased temperature may enhance the reaction rate, leading to a faster completion of the reaction. Overall, the system's energy dynamics will change as the heat is released, impacting both physical and chemical properties.
What else can I help you with?
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.
An insoluble substance produced by a reaction in aqueous solution is called an aqueous solid?
It is more likely to be called a precipitate.
What happens to ions in an aqueous solution?
Double Replacement
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.

What is the type of reaction between aqueous ammonia solution and an acid?
The reaction between aqueous ammonia solution and an acid is a neutralization reaction, where ammonia (a base) reacts with the acid to form an ammonium salt and water.
What term do you use to indicate salt solution in water in a chemical reaction?
(aq) It means aqueous. Example: NaCl(aq)
What is the symbol for solution in water in a chemical reaction?
(aq) aqueous.
What is the name of the reaction between aqueous ammonia solution and an acid?
The reaction between aqueous ammonia solution and an acid is called neutralization. In this reaction, ammonia acts as a base and reacts with the acid to form a salt and water.
What is the term for an insoluble solid substance produced from a reaction in aqueous solution?
The term for an insoluble solid substance produced from a reaction in aqueous solution is a precipitate. This forms when the ions in the solution react to form an insoluble compound that falls out of 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.
What is the balanced neutralization reaction between H2SO4 and KOH in aqueous solution?
The balanced neutralization reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH) in aqueous solution is: H2SO4 + 2KOH -> K2SO4 + 2H2O
When an aqueous solution of lithium chloride is mixed with an aqueous solution of ammonium sulfate what happens?
A chemical reaction occurs where lithium sulfate and ammonium chloride are formed. These products are both soluble in water and remain in solution. The reaction is: LiCl + (NH4)2SO4 → Li2SO4 + 2NH4Cl.
What happens to ions in an aqueous solution?
Double Replacement
Does an aqueous solution of CaNO32 and tin metal react?
A reaction doesn't occur.
