Chemical reactions that absorb energy will not occur without a source of energy true or false?
True. Chemical reactions that absorb energy, also known as endothermic reactions, require an external source of energy to proceed. Without this added energy, the reaction will not occur.
Describe the role of energy in chemical reactions?
Energy is required to break bonds between atoms in reactant molecules, allowing them to rearrange into new products. This energy is called activation energy. Some reactions release energy, called exothermic reactions, while others absorb energy, called endothermic reactions. Overall, energy is essential for driving chemical reactions and determining whether they proceed or not.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
What do chemical changes always take in or give off?
Chemical changes always involve the absorption or release of energy. This can occur in the form of heat, light, or some other form of energy.
When there is a chemical change is there an absorption of energy?
Yes, in a chemical change, energy is either absorbed or released. Endothermic reactions absorb energy from their surroundings while exothermic reactions release energy. The change in energy is often required to break and form chemical bonds during the reaction.
What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
What are chemical rections that absorb energy?
Endothermic Reactions
Are chemical reactions that absorb energy will occur without a source of energy?
false

Do chemical reactions transfer energy?
Yes, chemical reactions can transfer energy in the form of heat or light. Exothermic reactions release energy in the form of heat, while endothermic reactions absorb energy from their surroundings.
Does a chemical reactions that absorb energy will not occur without a source of energy?
Yes, it is true.
Is it true that Every chemical reaction gives off energy?
No, not every chemical reaction gives off energy. Some chemical reactions absorb energy, which is known as an endothermic reaction.
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
What are the chemical changes of electriciy?
CHEMICAL Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.
What is the type of chemical reaction in which heat energy is absorbed?
An endothermic reaction is a type of chemical reaction in which heat energy is absorbed from the surroundings. This results in a decrease in temperature of the surroundings and an increase in the energy of the reactants.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
