What is the emperical formula for C6H12?
Empirical formula gives the proportions of the elements present in a compound but not the actual numbers or the arrangement of atoms. The empirical formula for C6H12 is CH2.
Do chemical formulas show the total number of atoms in a sample of a compound?
Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.
How do you describe a compound made out of hydrogen and carbon atoms only?
Hydrocarbons
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
Write formulas for a compound with one calcium atom and two fluorine atoms and for a compound with two aluminum atoms and three sulfur atoms?
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
What is the empirical formula of MgO?
MgO is an ionic compound and all the ionic compounds are represented by their emperical formula because actual no of atoms can not be represented due to a very huge crystal formation.(crystal lattice).
What are formulas for a compound with one calcium atom and two fluorine atoms and a compound with two aluminum atoms and three sulfur atoms?
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
What is an emperical formula?
An empirical formula represents the simplest whole-number ratio of atoms in a compound. It does not provide information about the actual number of atoms present in a molecule. To determine the empirical formula, one must divide the subscripts of the compound's molecular formula by the greatest common divisor to obtain the simplest ratio.
Empirical formulas describe the types of atoms in a compound and their?
An empirical formula give information about the chemical composition of a compound. Example: tetracycline with the empirical formula C22H24N2O8 has the following composition: - carbon 59,44 % - oxygen 28,81 % - nitrogen 6,30 % - hydrogen 5,45 % If you're with plato the answer is ratios
Describe the differences between molecular formulas and structural formulas for molecular compounds?
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.
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.
