How do you identify a compound or an element?
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
What are the main difference between elements compounds and mixture?
An element is a single atom, while a compound is a molecule consisting of at least two different types of elements that cannot be physically separated. A mixture contains at least two different kinds of molecules or elements that can be physically separated.An element is a substance in which -same type of atoms added together.Eg: H2, Na, C & Ne etc.A compound is a substance in which -different atoms added together in a fixed ratio.Eg: CO2, H2O & NaCl etc.A mixture is also a substance like a compound in which -different atoms/compounds/elements added together but in a variable (not in a fixed) ratio Eg: salt water, air, living body, smoke etc.An element is any amount of one particular kind of atom.A compound is a combination of two or more different elements.A mixture is a substance made by combining two or more compounds without each substance chemically bonding.The difference is that a compound is chemically combined and a mixture is not chemically combined.Added:)An element is a substance that consist of a single type of atoms.Example: Iron, chlorine, oxygen etc.A compound consist of various elements or compounds (2 or more than 2 ) but they have the constituents in a definite proportion.Example: H2O, CO2, NH3 etc.A mixture consist of elements or substances in any, undefined proportion.Example: soil, air, gas, oil.The difference is that a compound is a chemically combined 'mixture' (well defined, with one set of properties) and a mixture is not chemically combined (in a non-defined, variable combination of compounds and/or elements, all with its own properties: kerosine/gasoline/naphta, moist/dry air).
Why fastidious organism grow poorly in chemically defined medium?
because fastidious organisms require specific nutrients that can not be supplied to them in the chemically defined medium therfore dont grow as well
1 iu is equal to how many mg?
The international unit varies according to the substance. An IU is the amount of something that is needed to produce an effect which has been agreed upon as a standard. So, 1000 IU of Vitamin D has a different mass than 1000 IU of Vitamin C.
Definition of Chemically defined media?
Chemically Composition is known & made with synthetic inorganic chemical substances.. Eg:- Glucose Broth, Inorganic Synthetic Broth
Why soft drink is called a mixture?
A mixture is defined as a substance containing two or more different substances that are not combined chemically. Soft drinks are made of different things, but are not all one chemical compound like water is.
Is ammonium nitrate a substance or mixture?
A mixture can be defined as a material composed of two or more different substances that are not chemically combined. This makes nitrogen a pure substance.

What contains two or more elements chemically combined?
A compound is defined as a pure substance made up of two or more types of elements (atoms) chemically combined in a fixed proportion, and it can be further subdivided into simpler substances by chemical means only.A molecule is the smallest part of a compound, whose properties are the same as those of the compound.
The ------ of a substance is defined as it mass divided by its volume?
weight is different in different gavities but mass is not, volume is not involved

Why would you obtain an impure substance if you mixed pure baking soda with pure salt?
A pure substance has to consist of only one component with defined physical characteristics and definite composition. Two pure substances mixed but not chemically bonded will have more than one component.
What are defined as necessary food substance?
Are defined as necessary food substances
What is the definition of chemically defined media?
A chemically defined media is a media in which the chemical nature of all the ingredients and their amounts are known. These media are also called synthetic media, mainly chemoorganotrophic heterotrophs also can be grown in defined media with glucose as a carbon source and an ammonium salt as a nitrogen source.
How are defined terms and undefined terms relate to each other?
"Defined items" are defined in terms of "undefined terms".
