No, our energy sources started from the sun (nuclear fusion) which made vegetation grow which turned into fossil fuels, or from stellar events which formed uranium. Then there are energy sources like wind, wave, and tidal, that are driven by the sun's energy, and direct solar energy. When we use fossil fuels, we are using a chemical reaction to release the energy contained in the fuel, but the original formation of the fossil fuel was driven by the sun. Energy from uranium is not chemical at all. Hydro power also depends on rainfall as the source of the energy, and that is caused by the sun's effect on the weather.
What else can I help you with?
The energy necessary to start a chemical reaction?
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
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 a good sentence for activation energy?
Activation energy is the minimum amount of energy that must be provided to start a chemical reaction.
Energy is the energy needed to start a chemical reaction?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that reactants must overcome to form products. This energy is needed to break bonds in the reactant molecules before new bonds can form in the products.
What is a sentence using the word activation energy?
Activation Energy is the required energy needed in order for a chemical reaction to start.
Do all chemical reactions need energy to start off?
yes they all need more or less start up energy
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
The energy necessary to start a chemical reaction?
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
What does the amount of energy affect during a chemical reaction?
A chemical reaction need an activation energy to start.
Is Activation energy is the energy needed to start a chemical reaction?
Yes!
The energy necessary to start a chemical reaction is called the?
activation energy
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 energy is needed to start a chemical reaction?
Activation energy is the energy needed to start a chemical reaction by breaking the existing chemical bonds in the reactants before new bonds can form in the products. This energy barrier must be overcome for the reaction to proceed.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
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.
What energy needs to to start a chemical reaction?
It varies with the differences in chemical reactions
Do all chemical reactions need heat to start them off?
No, not all chemical reactions require heat to start. Some reactions can occur at room temperature or even at low temperatures. Heat is often used to speed up reactions or provide enough energy to overcome the activation energy barrier.
