In all chemical reactions, energy is conserved, meaning that it cannot be created or destroyed, only transformed from one form to another. Reactions can either release energy (exothermic) or absorb energy (endothermic), depending on the nature of the reactants and products. The energy changes are often associated with the breaking and forming of chemical bonds. Overall, the total energy before and after the reaction remains constant.
What else can I help you with?
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
Do chemical reactions give out energy in the form of heat light or sound?
Yes, chemical reactions can give out energy in the form of heat, light, or sound. This energy is released due to the breaking and forming of chemical bonds during the reaction.
What helps chemical reactions occur?
Chemical reactions occur when reactant molecules collide with enough energy and proper orientation to overcome the activation energy barrier. Factors such as increasing temperature, using a catalyst, and adjusting reactant concentrations can all help facilitate chemical reactions by providing more energy for collisions or altering the reaction pathway.
What do chemical reactions in living organisms need to start?
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
Which compound is essential to all chemical reactions in a cell?
Adenosine triphosphate (ATP) is the compound essential to all chemical reactions in a cell. ATP serves as the primary energy currency of the cell, providing the energy necessary for various cellular processes.
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.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
Why is chemical energy needed in all chemical reactions?
To initiate a chemical reaction an activation energy is necessary.
Is it true that all chemical reactions are reversible?
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
What are some things that need chemical energy?
Candle and all Chemical reactions
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
Why is burning of gas considered a chemical change?
All burning reactions involve chemical reactions (chemical changes).
Which of the following is true for all exergonic reactions?
the reactants have more total energy than the products.
What are some things that need energy?
Candle and all Chemical reactions
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
