What are the two classes of matter?
Classifying Matter Matter can be classified into several categories.
Two broad categories are mixtures and pure substances.
A pure substance has a constant composition.
All specimens of a pure substance have exactly the same makeup and properties..
Which of the following is the simplest of substance?
ElementsExplanation: Elements are the simplest form of a substance.
What are the properties of an element in Mr Pureys lab?
Answer: These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.
What elements are in dry ice?
Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms.
Is compounds can be broken down by physical means?
Note that a compound: consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and.
Is ice a homogeneous mixture?
Ice is a homogeneous mixture since particles are distributed uniformly within it. In air, all gases would have a uniform composition. Therefore, the air is an example of homogeneous mixture.
Is Diamond an element?
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
Is ice an element or compound?
But why exactly does dry ice, a solid substance, turn into cold, white vapor at room temperature? The answer lies in its chemical composition. Dry ice is a compound consisting of one carbon dioxide molecule chemically bonded to two molecules of oxygen and not an element or a mixture.
What are the two substances mentioned in the poem?
The two substances mentioned in thepoem is element and compound.
What are two substances mentioned in the poem Mr Pureys lab?
What are the two substances mentioned in the poem Mr. Purey’s Lab?The answer is Elements And Compounds.yah i know.Oct 8, 2020
What do we call it when two or more elements are chemically combined?
When two or more elements combine to form a new substance, it is called a compound. … The smallest part of a compound is a molecule. A compound is made when atoms of two or more elements bond in a chemical reaction.
Which of the following Cannot be broken down into simple substance Brainly?
Explanation:Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element.
Is ferrous sulfate Cannot be broken down into simpler substances?
Answer: ferrous sulfate cannot be broken down into simpler substances.
Is compounds are more complex than elements?
Elements are the simplest complete chemical substances. Each element corresponds to a single entry on the periodic table. … Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What are two substances?
Two Main Types of Pure Substances Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it.
What is true about elements and compounds?
Elements are substances (like hydrogen and oxygen) that can’t be split into simpler substances. A substance like water, that is made up of two or more elements, is called a compound. … Compounds are usually very different from the elements that have combined together to make them.
Can a mixture be broken down?
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
