Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
A change of state where energy is given off?
Endothermic Reaction. Exothermic is a chemical reaction in which energy must be provided.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
What type of change occurs when sodium and chlorine combine?
Chemical change and exothermic change
What is released by an exothermic reaction?
what is released during a chemical reaction is ENERGY.
Is melting a penny an exothermic change?
Chemical, since it doesn't turn back.
What are the two types of energy change in chemical reaction?
endothermic and exothermic
What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
Why are fireworks considered a chemical change?
they are actually considered exothermic change because they release energy.
What changes in an exothermic chemical change?
A change that releases energy in the form of heat to its environment.
The melting of ice cubes is a exothermic reaction?
No, it is a physical change, not a chemical reaction.
