Which situation describes a reaction with a percentage yield of 100%?

Select one:
a. The amounts of reactants initially present are stoichiometric.

b. The product is more than the limiting reagent has the potential to produce.

C. none of them

d. No competing reactions occur and the limiting reagent is fully consumed.

C. none of them

Explanation:

When limiting reagent like the name implies is entirely consumed the reaction will not go to stoichiometric completion.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
