What does the formula of a substance tell you?
The formula of a substance(element or compound) tells us the number of molecules in the in the substance(element or compound).
What tells how many atoms of an element are contained in 1 molecules of a substance?
A molecular formula for the substance. The number of atoms of each element present is given by a subscript immediately after the chemical symbol for the element in the molecular formula, with a subscript of "1" being presumed when no subscript is actually written in the formula.
How many H atoms are present in a chemical formula?
By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
How do scientists distinguish between an element and a compound?
An element, is a pure substance that can not be broken down by chemical means. a compound, is a pure substance that can be broken down by chemical means. by knowing those two things a scientist can distinguish between the two. elements- 1. carbon 2. aluminum compounds- 1. sodium chloride 2. carbon monoxide
The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
How could you tell a pure substance from a solution if you didnt know what was in it?
The purity is determined by chemical analysis.
How can a chemical change help you tell the difference between a compound and an element?
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
What are two reasons why density is a useful property identifying substances?
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
What does the formula of a substance tell you?
The formula of a substance(element or compound) tells us the number of molecules in the in the substance(element or compound).
What is the formula for patassium?
Potassium is an element--the purest form of any substance. Technically the formula is just K as that is the elemental symbol. There are innumerable different compounds that include potassium in their formula.
How can you tell that substance compound by looking at its formula?
Characteristics of a substance are called properties. Substances have chemical properties - how they react with other substances and physical properties - boiling and melting point, colour, solid liquid or gas, smell...
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
How do you tell pure and mixture apart?
a pure substance only has one element and a mixture has many different compounds
How could you prove to someone that a clear material is a solution not compound?
well Tell the person its a pure substance so a pure substance can only compound one matter
How can a chemical change help tell the difference between a element and a compound?
its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
What information is contained in a chemical equation?
A chemical formula contains information on the types and spatial arrangement of bonds in the chemical.It also tells you what elements are in the chemical, and how many atoms of each. The spatial arrangement is not necessarily very obvious from the formula, e.g. C2H5OH does not tell you much about the spatial arrangement of the bonds.A chemical formula uses symbols and numbers o represent the composition of a pure substance
