Question

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

Answer 1

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

Step-by-step 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.

• In balanced chemical equation, the number of moles of reactants and products must be the same.
• From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.
