If you add a piece of hydrogen peroxide tiny gas bubbles will form. However if you crush the piece of potato first more gas bubbles will form. Explain these observations?

The crushed piece has a greater surface area, and so the reaction takes place easier and faster.

Is science based on Empirical observations or unchaning facts or solely on experiments?
Science is based on a mixture of all three: observations, laws of nature, and experimental data. The root of science, however, lies in observation.
What elements sugar compound contain?
Carbon, hydrogen and oxygencarbon, hydrogen, and oxygen. it is called glucose, fructose, saccharose, lactose, ....
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.
Is h2o toxic?
Hydrogen Peroxide (H2O2) is probably not toxic if consumed in very small amounts. It is possible that concentrations above 10% can cause serious neurological (brain) damage. However, do not attempt to consume it on purpose, as NASA use it as rocket fuel, and I personally wouldn't want to drink that.
What electron behavior in compounds are found in hydrogen?
Hydrogen has the electron configuration of 1s1 meaning that Hydrogen has only one electron. Because of this, Hydrogen is a moderately reactive substance and behaves atypically both in intermolecular and atomic bonding. The most notable behaviour of Hydrogen is Hydrogen bonding. When hydrogen is bonded to a highly electronegative element, such as Fluorine in HF, the electron density is pulled away from the weak hydrogen atom, leaving the hydrogen almost completely deprived of electrons and a δ+ charge. This induces nearby atoms in other molecules to share their lone pair electrons with the hydrogen, effectively producing a bond similar to a covalent bond, however between molecules. Hydrogen bonding is the strongest intermolecular force and is present in compounds such as water, where the Hδ+ Effectively 'bonds' with the lone pairs of the oxygen atoms in neighbouring molecules, which is why water and ice show unusual properties.
Will hydrogen peroxide cure acne?
No, Hydrogen Peroxide will not cure acne... Benzyl Peroxide, will however help it.
What enzyme filled sac is found in the liver and produces hydrogen peroxide?
Catalase, however it does not produce hydrogen peroxide but rather catalyzes the breakdown of hydrogen peroxide into water and oxygen gas.
Does peroxide contain hydrogen and oxygen?
Peroxide commonly refers to hydrogen peroxide, or H2O2, which is composes only of hydrogen and oxygen. However, in chemistry it can also refer to the peroxide ion O22- which is composed only of oxygen. The former usage of the term "peroxide" is more common.
Use of hydrogen peroxide in robots?
Hydrogen Peroxide is not directly use to a robot. It is however used along with a robotic devices. Hydrogen Peroxide is dispersed using the robotic device to detoxify hospital bugs.
Can water and hydrogen peroxide be considered the same?
No, water (H2O) and hydrogen peroxide (H2O2) are two separate chemicals. However, hydrogen peroxide is an unstable compound which will eventually become water and oxygen gas.
Does hydrogen peroxide remove oil?
No, hydrogen peroxide would not remove oil. Hydrogen peroxide is an oxidizing agent, which allows it to bleach certain stains. However, the removal of oil would require a surfactant/detergent.
Can hydrogen peroxide lighten arm hair?
Yes, hydrogen peroxide can be used for lightening hair. However, it will also bleach skin and probably then is not advisable for use on the arms.
If oxygen reacts with hydrogen what do you get?
Water , however if there is insufficient oxygen some hydrogen peroxide is formed, (H2O2 )
Is there a mixture using hydrogen peroxide to clean dark urine stains on a hardwood floor?
There is no mixture using hydrogen peroxide to clean dark urine stains on a hardwood floor. However, you can dip a rag into hydrogen peroxide and allow it to sit on the stain for about 10 minutes.
Is hydrogen peroxide a compound or elements or mixture?
H2O2 is a covalent compound, as a pure sample of it cannot be split into other separate compounds by physical means. However, the bottle labeled "Hydrogen Peroxide" in your medicine cabinet is actually a mixture (it's about a 3% solution of hydrogen peroxide the compound in water). I hope i could help out :)
Does hydrogen peroxide lose its ability to clean wounds if exposed to light?
Yes it does. I quote from a medical site: "Hydrogen peroxide can kill bacteria on contact and has been widely used for that purpose. However, straight hydrogen peroxide is unstable and rapidly loses its effectiveness when exposed to air or light." Hope this helps. (:
What to use instead of beta-dine?
If you are allergic to iodine you can use hydrogen peroxide, hurts less than rubbing alcohol. If those bother you then use an antibacterial soap, however hydrogen peroxide is better.
