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.
What are examples of compound in chemistry?
Compounds are pure chemical substances with two or more different chemical element that can be separated by chemical reactions. Examples include water compounds (oxygen and hydrogen), and table salt (sodium and chlorine).
Why is adding water mixed to sodium a chemical?
Everything in this world is a chemical or mixture of chemicals, its just that some are far simpler or far more complicated than others.
What is the chemical formula of sodium benzoate?
See the Web Links for "Answers.com: Sodium benzoate" to the bottom for the answer.
How can a compound be separated?
Yes. For example, water can be separated into oxygen and hydrogen gas by the chemical process of electrolysis. Molten sodium chloride can also be separated into sodium metal and chlorine gas by electrolysis.

What substance has a chemical symbol that is derived from a Latin name?
Two substances that have chemical substances derived from Latin are Au (from the word aurum) and Na (for natrium/sodium).
Is sodium chloride a mixture or solution?
Sodium chloride is a compound and not a mixture because it is a pure substance which cannot be separated physically. Mixtures contain components which are not chemically bonded, and thus can typically be separated by nonchemical means. However, all of the atoms in sodium chloride are bonded in a network and can only be separated with chemical methods.
When chlorine gas is separated from sodium chloride gas which change will occur physical or chemical?
It is a chemical change.2NaCl --> 2Na + Cl2
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
Ammonium chloride sodium hydroxide the formula?
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.

Is salt substance?
Yes, salts are chemical substances; for example table salt is sodium chloride (NaCl).
What kind of chemical reaction breaks up compounds into simpler constituents?
A decomposition reaction breaks up compounds into simpler constituents. The pattern for this reaction is AB --> A + B. An example is the electrolysis of sodium chloride (NaCl) into elemental sodium and chlorine, 2NaCl --> 2Na + Cl2.
How can a compound be separated?
Yes. For example, water can be separated into oxygen and hydrogen gas by the chemical process of electrolysis. Molten sodium chloride can also be separated into sodium metal and chlorine gas by electrolysis.
