A chemical equation that shows the formulas of the chemicals involved but not the proportions in which they react is called the a. word equation
b. balanced equation
c. skeleton equation
d. incomplete equation

C. skeleton equationFurther explanation

A chemical reaction can be expressed in terms of:

words  equationthe skeleton equation balanced equation

The skeleton equation is still in unbalanced form

so only chemical formulas of reactants and products so that the relative amounts of the reactants and products are not included

For example :

word equation

Ethane + Oxygen ⇒ Carbon dioxide + Water

skeleton equation

C₂H₆ + O₂ ⇒ CO₂ + H₂O

balanced equation

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

incomplete equation

2C₂H₆ + 7O₂ ⇒ 4CO₂(H₂0 is still missing)

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.
