A molecule, such as H20, is the smallest unit of a compound that maintains the characteristics of that compound. A compound often looks and behaves differently from its constituent elements. Consider a water (H2O)molecule, which is made up of two hydrogen atoms and one oxygen atom. Both hydr...

aThe molecule formula of a compound represents the actual number of atoms of each element present in a molecule. To find the molecular formula of a compound it is necessary to know both its empirical formula and its molecular or molarmass, which is usually some multiple of the mass calculated...
(c) What is its molecular weight?What atoms are contained in one molecule of chloride? How many of each?H2O (a) Is this an atom, molecule, or compound? (b) What type of bond is there: Ionic, polar covalent, nonpolar covalent, or hydrogen? (c) What is its molecular weight?
Is a molecule (carbohydrates,fat, protein,DNA/RNA) larger in size or a molecular complex (dimers, trimers, tetramers)? Answer and Explanation: A molecular complex is made up of multiple molecules. So assuming you are comparison a single type of mo...

If you could look at a polymer chain close up, you would see that the visual structure and physical properties of the molecule chain mimic the physical properties of the polymer. For example, if a polymer chain comprises tightly twisted bonds between monomers that are difficult to break, the ...
