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).
Hydrogen is not a mixture at all. It is an element and therefore a pure substance.
Neither. C2H2 is a compound (pure substance) so it is not a mixture at all. Hint: mixtures don't have chemical formulas.
The formula is H2O2 so in pure hydrogen peroxide it would be 50 mole %. As the molecular weight is 34 it would be 2/34 x 100 = 5.9 weight % (1 decimal place).
Sodium chloride (table salt) is a pure substance because it is a compound made up of sodium and chloride ions in a fixed ratio. It is not a mixture because it cannot be separated into its components by physical means.
Sulfur is not a mixture at all. It is a pure substance. Specifically it is an element.
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
Hydrogen Peroxide (H2O2) is a compound, and liquid at room temperature. It is NOT a mixture. However, at room temeprature it slowly decomposes to oxygen and water. 2H2O2 = 2H2O + O2 It the oxygen remains in solution in water then it is heterogeneous solution, NOT Mixture.
It is not a mixture at all. H2O2 is a (pure) compound
Hydrogen is not a mixture at all. It is an element and therefore a pure substance.
Hydrogen gas is a pure substance because it consists of only one type of atom, which is hydrogen. It is not a mixture because it does not contain different substances mixed together.
Yes, hydrogen gas is a pure substance because it consists of only hydrogen atoms. It is a homogeneous mixture of identical molecules, making it a pure substance.
Hydrogen chloride is considered a pure substance because it is a chemical compound made up of hydrogen and chlorine atoms in a fixed ratio.
No, hydrogen gas is an element, not a mixture. It consists of individual hydrogen atoms and is considered a pure substance.
Hydrogen peroxide is a compound, but it is too unstable to exist in pure form undermost conditions. Therefore, when encountered in a laboratory or during medical treatment, hydrogen peroxide is almost always a mixture with water.
Hydrogen gas is not an example of a mixture as it consists of only hydrogen molecules. It is a pure substance.
No. Hydrogen gas is an element, making it a pure substance.
It is neither and EXAMPLE Nor a MIXTURE. It is an elemental gas , found in the Periodic Table in position No. .1.
