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

A chemical reaction can be expressed in terms of:

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 :

Ethane + Oxygen ⇒ Carbon dioxide + Water

C₂H₆ + O₂ ⇒ CO₂ + H₂O

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

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

i think so it’s will be b yes i believe its
