10 Questions
What is the primary difference between the empirical formula and the molecular formula of a compound?
The empirical formula indicates the simplest whole number ratio of atoms of the elements present, while the molecular formula indicates the actual number of atoms of each element present in a molecule.
What is the significance of the limiting reagent in a chemical reaction?
The limiting reagent dictates the amount of product formed in a chemical reaction.
What is the purpose of the structural formula of a compound?
The structural formula indicates the arrangement of the atoms within a molecule of the compound.
How is the percentage yield of a reaction calculated?
Percentage Yield = (Actual Yield / Theoretical Yield) x 100%
What information does the empirical formula of a compound provide about its composition?
The empirical formula provides information about the elements present in the compound and their simplest whole number ratio.
In a chemical reaction involving two reactants, what determines the maximum amount of product that can be formed?
The limiting reagent
What type of formula indicates the actual number of atoms of each element present in a molecule of a compound?
