What else can I help you with?
Do all compounds have chemical formulas?
Yes, all compounds are molecules, but not all molecules are compounds
What general terms does a chemical equation indicate?
Chemical formulas of reactants and products; number of molecules involved in the reaction.
How are chemical names and formulas Related?
Chemical names and formulas are related in that chemical names provide information about the elements present in a compound and their arrangement, while chemical formulas provide a concise way to represent the elements and their ratios in a compound. A chemical name can be converted to a chemical formula using the periodic table to determine the elements present and their symbols, which are then combined based on the naming rules of the compound.
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
What are numbers that proceed symbols and formulas in a chemical equation?
These numbers are called coefficients (number of atoms and molecules)
What are related to chemistry?
Chemistry is the study of chemical composition of materials, of chemical reactions, of the structure of molecules, of molecules synthesis, etc. Chemistry is close to physics, mineralogy, biology.
In a chemical equation can you count the number of molecules?
Yes, you can count the number of molecules in a chemical equation by looking at the coefficients in front of the chemical formulas. Coefficients represent the number of molecules of each substance involved in the reaction. For example, in the equation 2H2 + O2 -> 2H2O, it shows that two molecules of hydrogen combine with one molecule of oxygen to form two molecules of water.
Do isomers of the same molecule have identical chemical properties?
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
How do the pictures compare to the chemical formulas?
Pictures visually represent the structure of molecules, showing the arrangement of atoms and bonds. Chemical formulas provide a symbolic representation of the elements and the number of atoms in a molecule. Pictures offer a more intuitive understanding of the molecular structure, while chemical formulas offer a concise and standardized way to represent the composition of a compound.
You want free software to draw chemical formula of molecules?
You can use software like ChemDraw or MarvinSketch, which both offer free versions for drawing chemical formulas of molecules. These programs provide a user-friendly interface and a wide range of tools for creating accurate chemical structures.
H2O CO2 and C12H22O11 are all examples of chemical .?

What is a compound and are compounds related to molecules?
A chemical compound is a pure chemical substance that consists of two or more different chemical elements which can be separated into simpler substances by a chemical reaction. A molecule is the smallest unit of a compound.
