Question
Stoichiometric coefficients, which are the numbers placed in front of each compound, are used to indicate ____.
Answer
Stoichiometric coefficients, which are the numbers placed in front of each compound, are used to indicate the relative number of moles of a given species involved in the reaction.
Note: The coefficients indicate that one mole of C9H20 gas must be reacted with fourteen moles of O2 gas to produce nine moles of carbon dioxide and ten moles of water.

Formula unit represents ____.
____ represents the empirical formula of an ionic compound, since they do not form true molecules, rather a coordinated lattice.

____ compounds form from elements of similar electronegativity.
Atomic weight is ____.
