The trend in acid strength has to be explained. Concept Introduction: A carboxylic acid can behave as a stronger bronsted acids when the hydrogen atom of alpha carbon is replaced by an anion. This condition is enhanced by: ( 1 ) The presence of electronegative atom. ( 2 ) The Greater positive formal charge on the central atom. ( 3 ) The Possibility of resonating structures for the anion that delocalize the negative charge on the anion, which lead to stability.

Solution Summary: The author explains that a carboxylic acid behaves as stronger bronsted acids when the hydrogen atom of alpha carbon is replaced by an anion.
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
Interpretation:
The trend in acid strength and the acid which have the highest pH and which have the lowest pH is to be stated.
Concept Introduction:
The pH is a measure of Hydronium ion concentration. The expression for pH is,
pH=−log[H3O+] (1)
Higher the value of Ka, stronger the acid and for the acidic solution pH<7, which means higher the value of Ka, smaller the value of pH.
The heat of combustion for ethane, C2H6C2H6 , is 47.8 kJ/g. How much heat is produced if 1.65 moles of ethane undergo complete combustion?
