Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
In a chemical reaction, only the electrons in the outer shell of the atom are involved, resulting in the formation or breaking of chemical bonds. This process typically involves smaller amounts of energy. In contrast, nuclear reactions involve the nucleus of the atom, where protons and neutrons are affected. Nuclear reactions release significantly more energy compared to chemical reactions due to the much stronger forces involved in altering the nucleus of the atom.
The letter A represents acid with regards to the DNA molecule (Deoxyribonucleic acid)
im think it is a physical change because there chemical bond are formed during ice makig.only a physical chage ocuur that the density of the water gets low and it becomes hard. regards Abdul karim
They're all well, and they send their regards.
With regards to energy, oil is a naturally occurring mixture of many different chemicals. We purify, or refine, it into more useful forms, such as diesel and gasoline. The energy itself is purely chemical, until the fuel is burned, at which point it generates heat and pushes the engine (kinetic energy), which ultimately drives the car or truck.
In all types of break down of food, there is a chemical reaction. regards.
This is an irreversible change as any cooked food cannot be returned to an uncooked state. This makes it a chemical reaction/change. Hope this helps, Kind regards, sasjade
Enzymes are biological catalysts, meaning they can speed up chemical reactions without being used up themselves. They do this by breaking down molecules, the molecules that each enzyme breaks down are different and they are called the substrate, so simply, each different type of enzyme can break down a different substrate. Enzymes have an area called an active site on them, this is where substrate is broken down. Hope this helps, I can explain in more detail if required

Chemical changes can cause the mass of matter to change. During a chemical reaction, bonds between atoms are broken and new bonds are formed, leading to the rearrangement of atoms. This can result in either an increase or decrease in the overall mass of the substances involved in the reaction.
Some body want to help me please, thank and best regards
The heat of solution refers to the heat energy absorbed or released when a substance dissolves in a solvent, while the heat of reaction refers to the heat energy absorbed or released during a chemical reaction. The heat of solution can be a part of the overall heat of reaction if dissolution of a substance is involved in the chemical reaction.
chemical changes disturbs the structure of the substance and hence reduce the mass....thx...with best regards..
The conventional bombs are the non-nuclear ones. They use a exotermic chemical reaction to obtain a sudden release of great amount of energy. In such weapons, nuclear fission and fussion are not significant source of energy, and radiocativity is not used as part of its offensive power. Regards, Mario/Brazil

dude its obvious that its chemical and do your homework by yourself next timekind regards The man
