An amphoteric species is one that reacts?
Acid or Base
What is an Amphoteric substance?
Amphoteric Substance is one that can react as either an acid or base."Partly one and partly the other; neither acid nor alkaline; neutral" (I don't think this answer is correct)The word is derived from the Greek prefix ampho- meaning "both".Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides. Other examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water and ammonia.
What is the different between reactive and non reactive metals?
one reacts and one doesn't
How easily one thing reacts with another is?
It is called a reactive element or compound.
What substances are formed when acids react?
That depends on what they react with. If an acid reacts with a metal the products are usually hydrogen gas and a salt. If one reacts with a base the products are usually water (or a weak acid) and a salt. If an acid reacts with a carbonate the products are carbon dioxide, water, and a salt.

What is an amphoteric salt?
Inchemistry, an amphoteric substance is one that can react as either an acid or base.Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides or hydroxides.Zinc oxide (ZnO) reacts differently depending on the pH of the solution:In acids: ZnO + 2H+ → Zn2+ + H2OIn bases: ZnO + H2O + 2OH- → [Zn(OH)4]2-This effect can be used to separate different cations, such as zinc from manganese.

What are examples of amphoteric oxides?
From the USDOT Pipeline and Hazardous Materials Safety Administration Glossary: A metal that is susceptible to corrosion in both acid and alkaline environments. Aluminum is an example of an amphoteric metal.
Is it possible for a chemical to behave as an acid in one instance and as a base in another instance?
Yes, but not at the same time. Such substances are called amphoteric. Their acidic or basic character depends on the substance they are reacting with.A good example of an amphoteric substance is water.When water reacts with a substance more basic than itself (like ammonia), it acts as an acid.H-OH + NH3 --> NH4+ + OH-When water reacts with a substance more acidic than itself (like hydrochloric acid), it acts as a base.HCl + H2O --> H3O+ + Cl-
What is the meaning of amphoteric?
Partly one and partly the other; neither acid nor alkaline; neutral.
Differentiate extra and intracellular enzymes?
An extracellular enzyme is one which reacts outside of the cell. An intracellular enzyme is one which reacts inside of the cell.
Is radium hydroxide amphoteric?
No, radium hydroxide is not amphoteric. An amphoteric compound is one that has characteristics of and is capable of reacting like either an acid or a base. Radium is a metal from Group 2 of the periodic table, and these Alkaline Earth metals form hydroxides that are definitely basic in nature. In general, amphoteric compounds will not be formed by metals at the end or through the middle of the periodic table, but will include poor metals or metalloids in their makeup. An example might be aluminum hydroxide. We see the poor metal aluminum forming Al(OH)3 molecules, which display characteristics of amphoterism. A link can be found below for more information.
When acetone reacts with hydrazine in ethanol what is formed?
One hydrazine reacts with two acetone to yield two 2-propanol and one nitrogen (gas).
Is Iron oxide an amphoteric oxide?
An amphoteric substance is one that can behave as a Lewis acid and a Bronsted base, iron is not amphoteric. The best examples of substances behaving as an acid and a base are found with metal hydroxides such as aluminum hydroxide and zinc hyhroxide. Only certain cations show amphoteric behavior, for example if NaOH is added in small amounts to solutions of Fe3+ and Al3+ both will initially form precipitates (rust colored iron hydroxide and white aluminum hydroxide). Because Al(OH)3 is an amphoteric hydroxide and Fe(OH)3 is not, adding more NaOH will redissolve the Al(OH)3 and leave Fe(OH)3 as an insoluble solid. Commonly encountered cations that form amphoteric hydroxides are Al3+, Cr3+, Zn2+, Pb2+, Sn4+ and Sb3+. (Source:http://employees.oneonta.edu/kotzjc/LAB/Complexation.pdf pages 28-29)
A protein that reacts with fibrinogen to form fibrin is?
The coagulation protein thrombin is what reacts with fibrinogen. This is one form of fibrin.
How many electrons will the metal sodium atoms lose when the metal reacts with a nonmetal?
Sodium loses one electron when it reacts with a nonmetal.
