What is the difference between chemical reation and nuclear reation?
Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances, while nuclear reactions involve the changes in the nucleus of an atom, resulting in the formation of different isotopes or elements. Chemical reactions typically involve changes in electron distribution, whereas nuclear reactions involve changes in the structure of the atom's nucleus. Additionally, nuclear reactions release much larger amounts of energy compared to chemical reactions.
All are examples of chemical reactions except?
Breaking a glass. This is a physical change as the glass does not transform into a different substance. Chemical reactions involve the breaking and forming of chemical bonds to produce new substances.
Breaking down food to get energy requires that what kinds of chemical reactions take place?
During the process of breaking down food to get energy, chemical reactions such as catabolic reactions occur. These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. Key catabolic reactions include glycolysis, the citric acid cycle, and oxidative phosphorylation.
Why does a change in teperature indicate that a change reaction may have occured?
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
Is there a chemical reaction in a cheesecake?
Cooking involve many chemical reactions.
Chemical reactions involve the making and breaking?
chemical bonds
Is reactions a chemical or physical?
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
What is the difference between chemical reation and nuclear reation?
Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances, while nuclear reactions involve the changes in the nucleus of an atom, resulting in the formation of different isotopes or elements. Chemical reactions typically involve changes in electron distribution, whereas nuclear reactions involve changes in the structure of the atom's nucleus. Additionally, nuclear reactions release much larger amounts of energy compared to chemical reactions.
Do chemical reactions make new substances?
Yes, chemical reactions involve the breaking and formation of chemical bonds, resulting in the formation of new substances with different properties than the original reactants.

Breaking a glass. This is a physical change as the glass does not transform into a different substance. Chemical reactions involve the breaking and forming of chemical bonds to produce new substances.
What transfers do all chemical reactions involve?
All chemical reactions involve the transfer of electrons between atoms or molecules. This transfer of electrons can result in the formation of new chemical bonds, breaking of existing bonds, and the rearrangement of atoms to form new substances.
Why do chemical reactions always involve a change in energy?
Chemical reactions involve the breaking and formation of bonds between atoms, which requires energy. The energy change in a reaction is needed to overcome the activation energy barrier and initiate the process. This change in energy is essential for the rearrangement of atoms and the formation of new substances.
What does chemical reaction have to do with making and breaking bonds?
Chemical reactions involve the breaking of bonds in reactant molecules and the formation of new bonds in product molecules. During a reaction, old bonds are broken as energy is absorbed, and new bonds are formed as energy is released. The breaking and forming of chemical bonds are essential for rearranging atoms and creating new substances during a reaction.
How do chemical reactions occur around the home?
Cooking and burning involve chemical reactions.
What about the energy of biochemical reactions is true?
Biochemical reactions involve the conversion of energy from one form to another, often from chemical bonds to cellular work. The energy changes in these reactions are regulated by enzymes to maintain the cell's energy balance. The energy released or absorbed in biochemical reactions is crucial for the cell to carry out its functions.

What of an atom's electrons are involved in chemical reactions?
The electrons farthest from the nucleus of the atom
