Question

A chemical equation can be used to solve stoichiometry problems provided that it

A.indicates only the forward reaction and not the reverse.

B.indicates that reactants are in the gas phase and are not solids or liquids.

C.includes the coefficients that are needed for balancing the equation.

D.includes the state of matter after each substance

Answer 1

The answer is c. The only things that you need to know is molar ratios which is shown by the coefficients. Everything else only matters when it comes to things like equilibrium.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Stoichiometric coefficients represents the number of individual atoms involved in the chemical equation.

As a result, stoichiometric coefficients help in balancing the equation because an equation can only become balanced when number of reactant molecules equal the number of product molecules or vice versa.

Therefore, we can conclude that a chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.
