What else can I help you with?
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..
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Is an engine moving a car chemical or physical?
The movement of a car engine is considered physical, as it involves the transformation of mechanical energy into motion. Chemical reactions may occur within the engine, such as combustion in the cylinders, but the overall process is primarily physical in nature.
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical in nature. The process involves the conversion of electrical energy into chemical energy, resulting in the decomposition of compounds into their constituent elements or ions.
Does chemical changes almost never occur in nature?
no
What is energy stored in a substance because of its composition?
Chemical energy is the energy stored in a substance due to its chemical composition. This energy is released when chemical reactions occur.
What energy transformation can occur only in autotrophs?
light energy into chemical energy
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..
The majority of spontaneous chemical reactions in nature are?
Exothermic, meaning they release energy in the form of heat or light. These reactions tend to occur spontaneously because they result in a decrease in the overall energy of the system.
What type of energy is a chemical energy form of?
Chemical energy is a form of potential energy that is stored within the bonds of atoms and molecules in a substance. When chemical reactions occur, this energy is released or absorbed.
Are chemical reactions that absorb energy will occur without a source of energy?
false
What energy transformation occur in a battery povered toy car?
Chemical energy to mechanical energy.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
What is the definition chemical energy?
Chemical energy is a form of potential energy stored within the chemical bonds of a substance. When chemical reactions occur, this energy can be released in the form of heat or light. It is a type of energy that is associated with the breaking and forming of chemical bonds.
Name an energy transformation that occurs in nature that transforms light energy into chemical energy?
"photosynthesis"
What is activation enery?
Activation energy is the amount of energy that a chemical reaction requires to occur.
