The most common and simplified method and convention of notating elemental composition and molar quantities of molecular compounds comes through their molecular formula. In water, its formula is H2O indicating it contains a single atom of oxygen and two of hydrogen.

Is holes appear in a worn-out shoe sole a physical or chemical change?
Physical, because the chemical composition of the show sole does not change.
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
How do the coefficients in a balanced equation compare quantites of two substances?
These coefficients show the number of molecules involved in the chemical reaction.
How do scientists show the shape of a molecule?
Scientists use a structural formula to show the shape of a molecule.
Does the chemical formula of an ionic compound show the atoms in a molecule?
No. The chemical formula of an ionic compound is a formula unit and represents the lowest whole number ratio of ions in the compound. Ionic compounds are not made of molecules.
What is a molecule how do scientists show the chemical composition of molecules give an example?
A molecule is the smallest unit of most chemical compounds. Scientists use a kind of shorthand called a chemical formula that shows the type and number of elements in a molecule. For example, a water molecule is written as H2O, which means there are 2 atoms of Hydrogen and 1 atom of Oxygen.
What do scientists commonly use isograms to show?
To show areas that have similar measurements of precipitation, temperature, gravity, magnetism, density, elevation, or chemical composition.
What is a method for showing what a molecule or compound contains?
Chemical analysis shows the contents of compounds and molecules. To identify the compound, you use qualitative analysis. To know exactly how much is present, quantitative analysis should be performed.
What do chemical equations show about compounds and elements?
Chemical equations represent chemical composition of reactants and products and also how does the reaction occur.
What is a molecule and How do scientist show chemical composition molecule?
cuz they are dead moleculesType your answer here...
What is chemical bookkeeping?
Symbols are used for elements, when writing chemical compounds. These clearly show reactions between molecules. This is chemical bookkeeping.
Is holes appear in a worn-out shoe sole a physical or chemical change?
Physical, because the chemical composition of the show sole does not change.
How will we justify that ice water steam are the three state of a substance and not different substance?
The chemical analysis show that the chemical composition of the molecule is the same.
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
How do different scientists spectra to figure out the composition of a star's outer layer?
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
How do the coefficients in a balanced equation compare quantites of two substances?
These coefficients show the number of molecules involved in the chemical reaction.
What is the chemical composition of caraway?
See some details at this link: http://ndb.nal.usda.gov/ndb/foods/show/236.But this is important to know that seeds contain many substances and it is impossible to write a chemical formula.
