No. For salts it depends on the difference in the energy required to break ionic bonds (heat absorbed) and the heat released while hydrating the ions. I once made a solution of NaOH in water, and it got very hot because I had a lot of NaOH so you need to be careful when making certain solutions. Check related link below.
What else can I help you with?
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What does the law of conservation of mass state that cannot be created or destroyed during a chemical reaction?
The law of conservation of mass (or matter) states that mass (or matter) cannot be created or destroyed during a chemical reaction. *Matter is anything that has mass and takes up space, so a lot of scientists call this the law of conservation of matter.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
What is the enthalpy of reaction-?
the heat released or absorbed in a reaction
Does a change in energy always occurr during a chemical reaction?
no
Can a physical change always take place during a chemical reaction?
Yes
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What goes under no chemical change in a chemical reaction?
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
What is it that undergoes no chemical change during a chemical reaction?
A catalyst does no change chemically.
How to calculate the change in enthalpy during a chemical reaction?
To calculate the change in enthalpy during a chemical reaction, subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the change in enthalpy for the reaction.
What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What change could happen during a chemical reaction?
the chemical shall be changed
