What do chemical reactions that absorb energy needed to occur what is it?

Endothermic reactions absorb heat from the environment.


Are chemical reactions that absorb energy will occur without a source of energy?

false


Does a chemical reactions that absorb energy will not occur without a source of energy?

Yes, it is true.


Can chemical reactions absorb energy?

Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.


Chemical reactions that absorb energy will not occur without a source of energy true or false?

This is true. Energy is required to begin all reactions.


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.


What is the relationship between the temperature and the rate of chemical?

Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..


What chemical reaction produces the sun and energy?

These are not chemical reactions but thermonuclear reactions.


Are exothermic reactions chemical?

Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.


When chemical reactions occur energy is always absorbed?

No, chemical reactions can be endothermic or exothermic.


What two kinds of energy changes can take place during a chemical reaction?

Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.


What do chemical changes always take in or give off?

Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
