Can pure substances be mixtures?
No, pure substances cannot be mixtures. A pure substance is made up of only one type of atom or molecule, with uniform properties throughout the sample. Mixtures, on the other hand, are composed of two or more different substances physically combined, each retaining its individual properties.
Is medicine pure substance?
Drugs may be pure substances but more frequently they are mixtures.
How are mixtures from pure substances?
Mixtures are combinations of two or more pure substances that retain their individual properties and can be separated by physical means. Unlike pure substances, which have a uniform composition and distinct properties, mixtures can vary in composition and may exhibit different characteristics depending on the proportions of the components. Examples of mixtures include air, saltwater, and salad, where each component remains identifiable and does not chemically change.
How do substances and mixters differ?
Substances are forms of matter that have a definite composition and distinct properties, such as elements and compounds. Mixtures, on the other hand, consist of two or more substances that are physically combined but retain their individual properties. Unlike substances, mixtures can vary in composition and can be separated by physical means. Examples of mixtures include air, salad, and saltwater, while pure substances include elements like oxygen and compounds like water.
Are Rolaids pure substances or mixtures?

Substances are divided into two classes?

What are pure liquids and how do they differ from other types of liquids?
Pure liquids are substances that consist of only one type of molecule, such as water or ethanol. They differ from other types of liquids, like solutions or mixtures, because they do not contain any other substances mixed in. This means that pure liquids have a consistent composition and properties throughout, unlike mixtures which can vary in composition and properties.
What do mixtures and pure substances have in common?
Mixtures and pure substances are both made up of different types of matter. However, mixtures contain two or more substances physically combined, while pure substances contain only one type of substance with a specific composition.
How do the two main classifications of matter differ?
The two main classifications of matter are pure substances and mixtures. Pure substances are made up of only one type of substance with specific chemical properties, while mixtures are made up of two or more substances physically combined with variable composition and properties.
What 2 catigories can matter be divided into?
Matter can be divided into two categories: pure substances and mixtures. Pure substances are made up of only one type of atom or molecule, while mixtures are composed of two or more different substances that are physically combined.

Are most substances around us pure substances ao mixture?
Most substances around us are mixtures, rather than pure substances. Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while pure substances are made up of only one type of particle.
