What are two properties of salt?
it is hydrogen and electrons
How are characteristic properties of given substance different from its other properties and chemical properties?
A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
Is energy in water from hydrogen molecules?
No. The hydrogen and oxygen in water are combined into a single substance; it does not get one property from hydrogen or another from oxygen but rather has its own unique set of properties based on how they are combined. It is unclear what "energy" you are referring to.
Is a pure substance flammable?
Some are flammable and some are not. This depends on the chemical properties of the individual substance. Nonflammable pure substance include helium, water, and gold. Flammable pure substances include hydrogen, hexane, and magnesium.
Is hydrogen a mixture or substance?
Substance
Does a compound produce a new substance with unique qualities?
Compounds are made out of atoms of different elements. The properties are different than the properties of the constituent elements.For example, Water is made out of Hydrogen and Oxygen. Both Oxygen and Hydrogen are gasses at room temperature. Water is a liquid at room temperature with very different properties.
How does a mixture of hydrogen and oxygen differ from a compound of hydrogen and oxygen?
A mixture of hydrogen and oxygen means that the two gasses would be mixed together, but remain chemically distinct from one another and retain their own properties. You would still have separate hydrogen and oxygen molecules. In a compound of hydrogen and oxygen, water, the two elements are chemically combined to form a new substance with its own set of properties.
Which substance releases hydrogen ions?
What is substance that releases hydrogen ion
What substance physical properties depend on the composition?
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small.
What are the chemical properties of hydrogen peroxide?
hydrogen+peroxide
What properties changes when substance changes?
When a substance changes, any or all of its properties can also change.
What are two physical properties that can that can vary when the substance with these physical properties that dose not change?
Temperature and amount of the substance do not change chemical properties.
