If there is any type of energy given offduring a chemical reaction, it is most likely to be heat or light. However, heat and light often come together, and there are more reactions known to give heat without light than the other way around. Thus, I would go for heat then. (simply put)
Tootsie pops are not science, it is simply candy. One may consider it science because it is candy and deals with reactions, but it is not science.
Unless it were to suddenly go up in flames..... Definitely a physical. Just take a breath and think about it! These are easy points!
It's not a change at all. It is simply what the firefly does. But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.
Kitchen foil despite sometimes being called tin foil is actually made of aluminium. Kitchen foil is simply very thin sheets of aluminium.
Atoms can be ionized in chemical reactions when they gain or lose electrons. In some reactions, atoms may rearrange into different molecules or compounds. However, atoms are not destroyed or vaporized during chemical reactions; they are simply rearranged into different combinations.
Simply chemical reactions. Unless you want to know something more specific?
Sublimation, per se, does not involve any chemical reactions. It is simply a physical change of a substance going from a solid to a gas without passing through the liquid phase.
What are you referring to by "rearrange?" Files are displayed in alphabetical order; to "rearrange" them, you would simply change their name.
Yes, atoms are conserved in chemical reactions according to the Law of Conservation of Mass, which states that matter can neither be created nor destroyed. Atoms can rearrange to form different molecules, but the total number of atoms before and after a chemical reaction remains the same.
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.
I have no idea what the word "good" means in the context of chemical reactions. Chemical reactions have no morality in and of themselves, they simply happen or don't happen. Or are you asking about the motives of the human chemists? Sorry, as worded this question can not be answered.
Yes because it is a chemical reaction and these reactions are irreversible
The heaving of ground due to ice formation is a physical change. This is because the molecules in the ice simply rearrange themselves as they freeze, without any chemical bonds being broken or formed.
Simply put, such a battery depends on a chemical reaction. Reactions can only take place when there is an inbalance between the chemicals. Once a balance is acheived then no more reactions can take place.
Matter can change forms through physical or chemical processes, such as melting, freezing, or chemical reactions. These transformations do not destroy or create matter; they simply rearrange atoms into new configurations. This principle is known as the law of conservation of mass, which states that in a closed system, the total mass of the system remains constant.
There is no chemical reaction between isopropanol and water, they simply mix.
