Are sodium and francium elements or compounds?
Sodium and francium are elements. Elements are substances that cannot be broken down into simpler substances by chemical means, whereas compounds are substances composed of two or more elements chemically bonded together.
Is baking soda a pure subsances?
Baking soda is a compound made up of sodium, hydrogen, carbon, and oxygen atoms. It is considered a pure substance because it has a definite chemical composition and cannot be separated into simpler substances by physical means.
How is a substance different from an element?
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.
Why is adding water mixed to sodium a chemical?
When water is added to sodium, a chemical reaction takes place where sodium reacts with water to form sodium hydroxide and hydrogen gas. This is a chemical reaction because new substances are being formed with different properties than the original substances.
What substance can not be broken down by chemical means sodium water ethanol or sucrose?
Sodium is a pure element and cannot be broken down by chemical means into simpler substances like water, ethanol, or sucrose. It is a fundamental building block of matter with its own unique properties and cannot be further decomposed through chemical reactions.

What would be regarded as compounds?
Compounds are substances formed by the chemical bonding of two or more elements. Examples include water (H2O) and sodium chloride (NaCl). Compounds have a fixed chemical composition and can be broken down into simpler substances through chemical reactions.
What is an element give 2 examples?
An element is a substance that cannot be broken down into simpler substances by chemical means. Two examples of elements are oxygen (O) and sodium (Na).
What substance can not be broken down by chemical means sodium water ethanol or sucrose?
Sodium is a pure element and cannot be broken down by chemical means into simpler substances like water, ethanol, or sucrose. It is a fundamental building block of matter with its own unique properties and cannot be further decomposed through chemical reactions.
What happens when sodium chloride is mixed with gold?
When sodium chloride is mixed with gold, there will be no chemical reaction as sodium chloride is a stable compound and gold is an inert metal. The two substances will simply mix together physically and can be separated again by physical means.
What is the example of subtances?
Substances are forms of matter that have a definite composition and distinct properties. Examples of substances include pure water (H₂O), table salt (sodium chloride, NaCl), and gold (Au). Each of these substances has a unique set of characteristics and cannot be separated into simpler components without changing its identity.
Elements and Compounds are called?
Elements and compounds are called substance....subtances can be either elements or compound....an elementis a substance that cannot be separated into simpler substances by ordinary means...!!a compound is a pure substance that contains two or more elements combined in afixed proportion.......example of the formation of a comp. :1. Sodium plus chlorine --> sodium chloride
What are Elements and counpounds?
Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen. A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds.
Can Chlorine be broken down?
Chlorine itself is a chemical element and cannot be broken down into simpler substances by chemical means. However, it can undergo chemical reactions to form various compounds, such as sodium chloride (table salt) when it reacts with sodium. In nuclear processes, isotopes of chlorine can be transformed into different elements, but this involves nuclear reactions rather than typical chemical decomposition.
