Solution Summary: The author explains the difference between chemical formula and chemical equation.
Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

Interpretation Introduction
(a)
Interpretation:
The difference between chemical formula and chemical equation needs to be explained.
Concept introduction:
Chemical formula is the expression of a molecule with some combination of symbols.
Chemical equation is the expression of a reaction in balanced form.
Interpretation Introduction
(b)
Interpretation:
The difference between stoichiometric coefficient and stoichiometric factor needs to be explained.
Concept introduction:
Stoichiometric coefficient is the number of moles of a particular species participating in a chemical reaction. Stoichiometric factor is the mole ratio.
Interpretation Introduction
(c)
Interpretation:
The difference between solute and solvent needs to be explained.
Concept introduction:
In a solution, the species with more mole fraction is solvent and the one with less mole fraction is solute. A solution is formed by dissolving a solute in a solvent.
Interpretation Introduction
(d)
Interpretation:
The difference between actual yield and percent yield needs to be explained.
Concept introduction:
Actual yield of a reaction doesn’t give any information regarding the efficiency of the reaction. It gives the amount only.
But percent yield gives a clear idea about the efficiency of the method used for the synthesis.
Interpretation Introduction
(e)
Interpretation:
The difference between consecutive reactions and simultaneous reactions must be explained.
Concept introduction:
Consecutive reactions are those in which product of a reaction is acting as the starting material of another reaction.
Simultaneous reaction is kind of parallel reaction in which one species is reacting independently in many ways to give various products.

Some important notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
