Which form of energy is released or absorbed in most chemical reactions?
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)
How is a tootsie pop science?
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.
Is ploughing a field chemical change or a physical change?
Unless it were to suddenly go up in flames..... Definitely a physical. Just take a breath and think about it! These are easy points!
Is a firefly giving off light a chemical or physical change?
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.
What is the chemical name for foil?
Kitchen foil despite sometimes being called tin foil is actually made of aluminium. Kitchen foil is simply very thin sheets of aluminium.
What are the processes so that you can have chemical change?
Simply chemical reactions. Unless you want to know something more specific?
What are the chemical reactions involves in sublimation?
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.
How do you rearrange files in Unix?
What are you referring to by "rearrange?" Files are displayed in alphabetical order; to "rearrange" them, you would simply change their name.
Was making ammonia a good chemical reaction?
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.
Is toasting bread is reversible change?
Yes because it is a chemical reaction and these reactions are irreversible
When a battery is used up why is its stored chemical energy used up?
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.
What reactions occurs when rubbing alcohol and water?
There is no chemical reaction between isopropanol and water, they simply mix.
Are atoms conserved in chemical reactions?
The same number of each type of atom (each element) still exists after a chemical reaction. They simply attach to other atoms (or detach) in various ways to form molecules (or molecules break apart into atoms).
How do you convert nuclear energy into chemical energy?
I don't know of any way to do this. Nuclear energy simply provides heat, so could conceivably be used to drive chemical reactions, but I don't think this has ever been done.
How do dust storms destroy the desert?
Dust and sand storms do not destroy deserts, they simply rearrange the substrate a bit.
Who invented precipitation?
No one invented it its simply a form of chemistry reactions.
Difference between nuclear reaction and chemical reaction?
AnswerNuclear reactions involve changes in the nucleus of atoms -- the number of protons and/or neutrons is changed. Chemical reactions do not cause any changes at all in the nucleus. Instead, in a chemical reaction, the electron clouds of atoms are interacting, and all changes are occurring with the electrons that surround the nucleus.
