What chemical reaction happens to salt when you heat it?
when we heat the salt there chemical reaction is takes place
How an element produce heat?
A chemical reaction took place creating a new element.
What is the heat element in plaster?
There is no specific element in plaster that produces. The chemical reaction that results when plaster is mixed with water is what produces the heat.
What is exothermil?
A reaction that gives off heat . A reaction that takes in heat is ENDOTHERMIC.
What is an endothothermic reaction?
A chemical reaction whereby it takes in heat as supposed to giving it out (as opposed to an exothermic reaction).
What is a reaction which takes in energy?
endothermic
What chemical reaction takes up heat but the surroundings become cooler?
any reaction that takes up heat cools the surrounding and are thus called ENDOTHERMIC reactions. ex: - thermal decomposition in these reaction a compound takes up heat from the environment to break down into other substances. ex: - CaCO3 ==> CaO + CO2
Does fire have more than one element in it?
Yes. A fire is a chemical reaction giving off heat. The reaction requires material with more than one element.
What happens in a exothermic reaction?
In an exothermic reaction, the total making and breaking of bonds results in a net release of energy.
What are the ways that heat takes part in a chemical changes?
Heat can be involved in a chemical reaction that is endothermic(absorbs heat) or that is exothermic(releases heat)
What is the chemical reaction that uses heat to decompose an compound?
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
When the energy given off in a reaction is primarily in the form of heat the reaction is called?
when one element replaces another in a compound when the reaction has occured
