What is the connection between spontaneous reactions and free energy?
Spontaneous reactions release free energy. If a reaction is spontaneous, it means that it can occur without outside intervention because the products are at a lower energy state than the reactants, and the excess energy is released as free energy. The change in free energy (ΔG) for a spontaneous reaction is negative.

No. Chemical energy is stored in chemical bonds.
Is the Bunsen burner made for experiments or by accident?
The Bunsen burner was intentionally designed by Robert Bunsen in the 19th century for laboratory experiments. It was created to produce a hot, clean flame for heating, sterilizing, and performing chemical reactions in a controlled manner.
An example of a chemical reaction that absorbs heat energy and stores it in the chemical bonds of the product is photosynthesis, where carbon dioxide and water react in the presence of sunlight to produce glucose and oxygen. The energy from sunlight is absorbed during the reaction and stored in the bonds of glucose.
Can electron excitation happen in a semiconductor nanoparticle without light or thermal energy?
Yes, electron excitation in a semiconductor nanoparticle can occur without light or thermal energy through mechanisms like electrical injection, impact ionization, or tunneling. These processes can lead to electron promotion across energy levels within the nanoparticle, resulting in excitation.
What is light energy converted into chemical energy in which organic molecules?
In photosynthesis, light energy is converted into chemical energy in organic molecules such as glucose. This process occurs in the chloroplasts of plant cells, where pigments like chlorophyll capture light energy and convert it into chemical energy through a series of reactions known as the Calvin cycle.
Who has the ability to turn light energy into chemical energy?
Plants have the ability to turn light energy into chemical energy through the process of photosynthesis. This process involves capturing light energy with chlorophyll and converting it into glucose, which is used as energy for the plant's growth and survival.
How is the stored chemical energy transformed into thermal energy at point D?
The stored chemical energy is converted into thermal energy at point D through combustion. When the stored energy is released through combustion, it produces heat as a byproduct which raises the temperature of the surroundings. This thermal energy can then be utilized for various applications.
How is chemical energy transformed into heat?
Energy can only really be changed into other forms of energy. However, you can use energy to generate force, pressure, torque, etc.
For example, when gasoline is burned in a car engine, chemical energy gets converted into mechanical energy (sort of like force times speed).
What is the positive side in chemical industry?
The positive side of the chemical industry includes innovations in materials science, development of life-saving pharmaceuticals, advancements in renewable energy technologies, and improvement of agricultural productivity through fertilizers and pesticides. Additionally, the chemical industry contributes significantly to economic growth and provides numerous job opportunities worldwide.
What is the free energy for C2O4-2?
The free energy for the C2O4-2 ion can vary depending on the specific conditions such as temperature and pressure. To calculate the free energy for C2O4-2, you would typically need to know the free energy of formation for the ion under standard conditions and apply appropriate corrections based on the specific conditions of interest.
A chemical switch is a molecule that can change its structure or properties in response to a specific stimulus, such as light, temperature, or pH. This switch-like behavior allows for controlled manipulation of chemical processes and can be used in various applications, such as drug delivery or sensing.
What are the energies in food potential energy?
The energy in food is primarily in the form of potential energy stored in the chemical bonds of molecules like carbohydrates, fats, and proteins. This energy is released during digestion and metabolism to fuel cellular processes and provide the body with energy for various functions.
What do you call the process by which plants convert solar energy into chemical energy?
Photosynthesis is the process by which plants convert the energy from the sun's light into chemical energy.
What is the free energy change of the hydrolysis of ATP to ADP?
The free energy change of the hydrolysis of ATP to ADP is around -30.5 kJ/mol under standard conditions in the cell, making it an exergonic reaction that releases energy. This energy is utilized to drive various cellular processes.
How is light energy related to chemical energy?
Light energy can be absorbed by chlorophyll in plants during the process of photosynthesis, converting it into chemical energy in the form of glucose. This chemical energy is used by plants and other organisms as a fuel source for various metabolic processes.
What is internal energy in chemical bonds between atoms which is a form of potential energy?
Internal energy in chemical bonds between atoms refers to the energy stored within the bonds holding the atoms together. This energy is a form of potential energy and is related to the arrangement and interactions of the atoms within the molecule. It represents the energy required to break the bonds or the energy released when new bonds are formed during a chemical reaction.
How many joules of energy in 1 stick of dynamite?
On average, a stick of dynamite contains about 1 billion joules of energy. This energy is released in an explosive reaction when the dynamite is detonated.
How does stored chemical energy relate to chemical bonds?
Stored chemical energy is a form of potential energy that is stored in the chemical bonds of molecules. When these bonds are broken during a chemical reaction, the stored energy is released, typically in the form of heat or light. The amount of energy stored in a chemical bond depends on the specific atoms involved and the type of bond they form.
The process responsible for the enormous energy in the sun is?
The process responsible for the enormous energy in the Sun is nuclear fusion. In the core of the Sun, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. This energy is what powers the Sun and sustains life on Earth.
What is the benefit of oil and natural gas energy?
Oil and natural gas energy is only a small part of the Oil Industry. Keep in mind, the oil used for your car, the propane for you BBQ, the Butane for your lighters, soldering irons, and blowtorches, and even more all come from the Oil Industry. It is beneficial because it is so common. It is not beneficial because it isn't renewable.
What causes bubbles to form when electricity is passed through acidic water?
The bubbles are hydrogen and oxygen, formed from the electrolysis of the water by the electric current.
