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...

∙ 9y agoA chemical substance is any element or compound with a constant composition. Its characteristics include various types of physical and chemical properties, including density, melting point, electrical conductivity, components (atoms, molecules, formula unit), physical state under certain conditions, flammability, among many others.

What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
Give an example of the chemical formula of a compound What does this example tell you about the compound?
The formula of a compound called methane is CH4. This formula shows, among many other things, that there are four times as many hydrogen atoms as carbon atoms in methane and that each molecule contains 5 total atoms.
Is C6H12O6 a compound or a element?
Yes c6h12o6 is an organic compound. Most compounds have have carbon but not all things that have carbon are organic. c6h12o6 means there are six parts carbon, twelve parts hydrogen, and six parts oxygen.
How can you find the molecular formula of a compound when its percentage composition is given?
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)
How do you tell how many elements are in a compound formula?
A chemical formula will always tell you how many of each element is in a particular formula. For example glucose (C6H12O6) contains six carbons, twelve hydrogens and 6 oxygens. All together this is three elements, and 24 atoms. Try water..the chemical formula is H2O. So it contains two hydrogen atoms, and one oxygen atom. This is two elements, but three atoms. I hope this helped!
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).
How can you tell a substance is a compound by looking at its' formula?
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
How can you tell that a substance is a compound by looking at it formula?
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
How do you tell if a compound is saturated by looking its formula?
saturated compounds have the general formula CnH2n+2
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 does a compound's formula tell?
* * * *
What does a subscript tell us in a binary nonmetal compound?
In a binary compound, the subscript for a compound's formula would tell us how much of a certain atom there is.
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 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 you tell the difference between ionic and covalent bond only by looking at the chemical formula?
A compound formed by ionic bond will have charges written on the Chemical formula of the compound since ionic compounds carry charges. But, covalent compounds won't have charges associated with them because they are not formed by the transfer of electrons. Another way of telling the difference is by looking at the valencies. One of the elements present in a covalent compound will have tetra-valency i.e., a valency of 4.
What is the fluid with a density of 1.3?
I'm not sure what substance has that density, but what i can tell you is that the substance your looking for is a gas.
Does a chemical formula tell you how many atoms of an element are in a unit of a compound?
yes it does
