a chemical equation can be used to solve stoichiometry problems provided that it\no indicates only the forward reaction and not the reverse.\no indicates that reactants are in the gas phase and are not solids or liquids.\no includes the coefficients that are needed for balancing the equation.\no includes the state of matter after each substance.

Answer

Brief Explanations:

Stoichiometry problems rely on balanced chemical equations. The coefficients in a balanced chemical equation are used to establish mole - ratios between reactants and products, which are crucial for stoichiometric calculations. A chemical equation doesn't have to only show the forward reaction (reversible reactions can also be used in stoichiometry), reactants don't have to be in the gas phase, and while the state of matter can be useful information, it's not essential for basic stoichiometry calculations.

Answer:

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