What is a substance that cannot be broken down into simpler substances?
A substance that cannot be broken down is a pure substance
What is an element as a substance which cannot be separated into simper substances?
Diamond. Diamond is composed strictly of carbon, covalently bonded to one another creating a covalent network, making it the hardest substance in the world. Also, graphite of your pencil is composed strictly of carbon, except that the structure is different than diamond.
Pure substance that cant be broken down?
a pure substance is made up of only one type of atom. atoms can't be broken down (divided) definition of an atom: that which cannot be divided. there ya go! ur welcome :) -shamansh
True or false when a substance burns matter is destoryed?
false: matter cannot be destroyed
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Which of the following cannot be classified as a substance a air B gold c table salt d nitrogen?
All matter is a substance.
Which of the following cannot be classified as a substance gold nitrogen table salt or air?
Air cannot be classified as a substance because it is a mixture of various gases like nitrogen, oxygen, and carbon dioxide. Substances, on the other hand, are pure materials composed of one type of atom or molecule.
Why is the substance of magnesium classified as a element?
Magnesium is classified as an element because it is a pure substance consisting of only one type of atom, which is magnesium. Elements are the simplest form of matter and cannot be broken down into simpler substances by chemical means.
Which of the following substances can be separated into several elements nitrogen air aluminum and why not zinc?
Aluminum can be separated into its elements because it is a pure substance composed of only one type of atom. Similarly, nitrogen can be separated into its elemental form because it is a diatomic molecule. Zinc, on the other hand, is already an element and cannot be separated into simpler substances through normal chemical processes.
Is ammonia NH pure substance or mixture?
Ammonia (NH3) is a pure substance. It is a compound made up of nitrogen and hydrogen in a fixed ratio, and it cannot be separated into simpler substances by physical means.
What is the simple substance?
A simple substance is a substance that is made up of only one type of atom or molecule. It cannot be broken down into simpler substances by ordinary chemical processes. Examples include elements like oxygen, hydrogen, and nitrogen.
Do you agree that all homogeneous matter can be classified as pure substance?
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.
Matter has a uniform and definite composition called what?
Substance, classified as an element and compound. For an element, it cannot be separated into another simplier substance; for a compound, it can be dicomposed into elements using chemical processes.
Can a substance be both a conductor and a insulator?
No, a substance cannot be both a conductor and an insulator simultaneously. Conductors allow the flow of electricity, whereas insulators do not. Materials are classified as conductors or insulators based on their ability to conduct electricity.
Which pure substance can be classified as an element?
These are the chemical elements from the periodic table of Mendeleev.
Is gas hotter then liquids?
For a given substance, yes, it's gaseous form is hotter than its liquid form. However, you cannot say that a gas, of any substance, is generally hotter than a liquid of some other substance. Different substances have different boiling points. The boiling point for Nitrogen, for example, is well below the boiling point of water, and even below the freezing point of water. So you cannot say that Nitrogen gas is hotter than liquid water.
If a substance cannot be separated physically it is?
A substance that cannot be separated physically is a pure substance.
