What is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
Difference between endothermic and endergonic?
Endergonic means "absorbing energy in the form of work." Endergonic reactions are not spontaneous. An exergonic reaction is a chemical reaction where the change in the free energy is negative, indicating a spontaneous reaction.
What chemical reaction that absorbs heat called?
Endothermic reactionFor endothermic reactions Hfinal > Hinitial and DH is positive (+DH)It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !
Is an endothermic reaction a chemical change?
Yes.
What is a endothermic?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. change in H> 0.(6.6)
What are the two types of energy change in chemical reaction?
endothermic and exothermic
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
Why is brownies a chemical change?
Because it is a mixture until it is baked and went through a chemical change and it is an endothermic reaction.
What is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
What is the definition of endothermic change?
Endothermic describes a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. (adjective)
Is burn a physical change?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..

Is energy released through chemical change?
It depends on whether or not the chemical reaction is exothermic or endothermic. If exothermic, then yes, energy is released. If endothermic, then no, energy is absorbed, not released.
Is heat liberated or absorbed when a chemical change takes place?
It depends on the reaction. An exothermic reaction releases (liberates) energy and an endothermic reaction absorbs energy.
