Technically, a non-pure substance is called a compound, so substance should not be used as an official scientific term. If you do come across the term 'substance', use context to decide. e.g. "Scientists isolated the substance boron." would be a pure substance, as boron is a single element.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Yes, all homogeneous matter can be classified as a pure substance because it has a uniform composition throughout. This means that all samples of the matter have the same properties and composition, making it a pure substance.
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
it is a pure substance.... not
Methane is a pure substance.
There is no such thing. An element IS a pure substance.
A mixture is not a pure substance since it contains various substances. A pure substance in one that is not mixed with any other thing.
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
a element is a pure substance
An element.
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
A pure substance is a material made of only one type of particle, such as atoms or molecules, and all the atoms in a pure substance have the same atomic number or number of protons. This means that all the atoms in a pure substance are of the same element.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Yes, when the substance is pure
Chicken multiplied by the numerator of 64= Peanut Butter
A mixture has different properties throughout; a pure substance has the same properties throughout.
