Given a balanced chemical equation it is always possible to determine A)
the physical state of the products and reactants
B)
whether a reaction will or will not take place
C)
the relative number of moles taking part in the reaction
D)
the conditions necessary for the reaction to take place

C)  the relative number of moles taking part in the reaction

Explanation:

From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.

The number of moles is the amount of the reacting specie that makes up a chemical reaction.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
