What substance can only be broken down by chemical means?

What substance can only be broken down by chemical means?

Compounds
Compounds are pure substances formed by the combination of elements; they can be decomposed by ordinary chemical means. Baking soda is a compound; it contains the elements sodium, hydrogen, carbon, and oxygen, and it decomposes on heating. Compounds can be separated into their components only by chemical change.

Which two substances can not be broken down by chemical change?

Among the given substances, the one that cannot be broken down by a chemical change is arsenic. It is one of the elements which is present in the simplest units. Ammonia, ethane and propanal are the three compounds, and they break down by a chemical change to give simple elements.

Which of the following substance Cannot be broken by a chemical method?

Helium is a element, and cannot be broken down by a chemical method.

Which substance Cannot be broken down by a chemical change because it is only one type of atom?

An element is a chemical substance that is made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element.

Which two substances can not be broken down by a chemical change?

Among the given substances, the one that cannot be broken down by a chemical change is arsenic. It is one of the elements which is present in the simplest units. Ammonia, ethane, and propanal are the three compounds, and they break down by a chemical change to give simple elements. Therefore, the correct option is c).

Can CuO be broken down?

Explanation: CuO can be made from copper and oxygen. Once produced it is a compound as it cannot be separated into components by physical means, but it can be broken down to Copper and oxygen by chemical means.

Which of the following Cannot be broken down into simple substance?

Elements
An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance.

What two substances Cannot be broken down by chemical changes?

Elements are the simplest forms of matter and therefore cannot be broken down into simpler substances by any chemical or physical means. Elements are the building blocks for all other substances. Some examples of elements include hydrogen, oxygen, carbon, and sulfur.

Can ethanol be broken down by a chemical change?

Ethanol, sucrose and water are composed of atoms of several different elements so we can decompose them with adequate chemical reactions.
