Chemical Energy
Chemical energy is a form of potential energy, and is present in various things such as foods, fuels and batteries. It may be released during a chemical reaction, often in the form of heat.

What is the best example of a substance that contains chemical energy?
Gasoline is a common example of a substance that contains chemical energy. When gasoline undergoes combustion, the stored chemical energy is released as heat and light energy, making it a valuable source of energy for various applications such as powering vehicles and machinery.
What is the first stage in cellular respiration that splits a molecule of glucose to release energy?
The first stage in cellular respiration that splits a molecule of glucose to release energy is glycolysis. Glycolysis occurs in the cytoplasm and involves the breakdown of glucose into two molecules of pyruvate, producing a small amount of ATP and NADH in the process.
Rhyolite is a fine grained extrusive igneous rock similar to granite. Rhyolite forms from particularly viscous molten lava and is grey, brown or reddish in colour, darkening with age. Rhyolite is essentially composed of feldspar, mica and quartz with numerous accessory minerals present :)
How are chemosynthetic organisms and plants similar as energy?
Chemosynthetic organisms and plants both create energy through biological processes. Chemosynthetic organisms use inorganic molecules to produce energy, while plants use sunlight for photosynthesis. Both processes are the foundation of the food chain and are essential for supporting life in their respective ecosystems.
Does a kerosene heater convert chemical energy to heat?
Yes, a kerosene heater works by burning kerosene, which releases energy in the form of heat through a combustion process. This process involves converting the chemical energy stored in kerosene into heat energy that warms up the surrounding area.
Answer 1: A compressional wave is a wave that is close together and transverse waves are waves that are going the way the wave travels.
Answer 2: Basically, it's a sound wave. A compressional wave is a wave that travels back and forth, moving with compression. Scince it is a mechanical wave it must use a medium to travel though. A sound wave is a good example of a compressional wave.

How is a life jacket made from petroleum?
Life jackets are made by a petroleum byproduct, that is mixed with acids and other alcohols. The product from it, Polyurethane. Polyurethane is heat, shock, scratch, and tear resistant. The foam made from it is what allows life jackets to float.
Does the temperature increase or decrease when energy is released during a chemical reaction?
The temperature increases when energy is released during a chemical reaction.
Are endothermic reaction products stable?
It depends on a few things. If you mean thermodynamically stable, then no. The product of an endothermic reaction is higher in potential energy than the reactant(s) and will eventually release that energy and revert back (if it doesn't go on to some other product).
If you mean kinetically stable, then maybe. It really depends on the relative energy of any intermediates formed in the conversion of reactant(s) to product(s). This relative energy is also known as activation energy. If the activation energy is high, then the product would be relatively stable. If the activation energy is low, then the product would not be stable.
Is there net absorption of energy when more energy is absorbed than released?
Yes, there is a net absorption of energy when more energy is absorbed than released. This means that the system gains energy overall.
Chemical reactions that release energy will always explode?
No, not all chemical reactions that release energy will explode. Some reactions may release energy in the form of heat or light without causing an explosion. Explosion occurs when there is a rapid release of energy in a confined space, resulting in a sudden increase in pressure.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.
Endo- means 'inside' which is where the energy ends up.
Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Non-conductors or insulators must be neutralized with?
Non-conductors or insulators must be neutralized with the removal of excess charge through processes like grounding or discharge to prevent a buildup of static electricity. This is important to avoid potential safety hazards and damage to electronic equipment.
What captures the energy from sunlight and converts into chemical energy?
Chlorophyll is the pigment that captures sunlight in plants and algae. Through the process of photosynthesis, chlorophyll converts this light energy into chemical energy in the form of glucose and other carbohydrates.
These rod-like structures are called mitochondria. Mitochondria are often referred to as the "powerhouses" of the cell because they are responsible for converting sugars and other nutrients into energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.
- Exothermic reaction
- Decrease in entropy
- Increase in entropy
- Positive change in free energy
- Negative change in free energy
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
Is it true that Every chemical reaction gives off energy?
yes it does
<><><>
No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
What two classes of chemical are involved in a neutralization reaction?
Acids and bases are the two classes of chemicals involved in a neutralization reaction. Acids donate protons (H+) while bases accept protons, resulting in the formation of water and a salt.
What captures external energy and converts it to energy within the cell?
The process you are referring to is called photosynthesis. Photosynthesis occurs in plant cells and some bacteria, where light energy from the sun is captured by chlorophyll and converted into chemical energy in the form of glucose. This process is essential for producing food and energy for the cell's survival.
Is making toast in a toaster an example of coverting light energy to chemical energy?
No. It is not really a change at all. When you turn on a light you simply allow electrons to flow through a circuit and through a tungsten filament. The tungsten has high resistance and so electrons loose energy through collisions and release light at many various wavelegths. No materials are undergoing any changes. They end upp the same way as they started.
What element is used to make a P-type mixture?
Boron is typically used to make P-type semiconductor materials by doping silicon with small amounts of boron atoms. This introduces positively charged "holes" in the crystal lattice, creating a deficit of electrons and resulting in a positive charge carrier concentration.
The chemical storage molecule for energy?
Adenosine triphosphate (ATP) is the primary chemical storage molecule for energy in cells. When energy from food is needed, ATP is broken down into adenosine diphosphate (ADP) and inorganic phosphate, releasing energy that can be used for cellular processes.
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing a decrease in temperature. This type of reaction requires an input of energy to proceed.
