Why is there a discrepancy between a heat of reaction ob-tained from calorimetry and one obtained from bond energies?

While bond energies and bond enthalpies can be used to estimate the heat of reaction (enthalpy change of a reaction), H, the heat of neutralization is the heat released when 1 mole of water is generated by the reaction of an acid and a base (reaction).

For the same type of bond, bond enthalpies differ from compound to compound. For instance, the C-H bond enthalpy in methane is nearly identical to that of ethane, butane, etc. When we look up the bond enthalpy for a C-H bond in a table of bond enthalpies, the average number that results may only be accurate to two or three significant figures.

Each compound's enthalpies of production are listed, and those numbers take into account any minor variations in the enthalpies of each bond. Therefore, the result will be more accurate if you utilize formation enthalpies rather than average bond enthalpies to compute a given reaction's enthalpy change.

How do you convert ethane to ethanoic acid? (with equation please).
Bess [88]
Ethane can be turned into its carboxylic acid form called the ethanoic acid by a series of steps. First chlirinate it in the presence of light. Then, add potassium hydroxide to get an alcohol. Finally, adding KMnO4 to oxidize it to a carboxylic acid. The equations are as follows:
C2H6 + Cl2  ---> C2H5Cl + HCl
C2H5Cl+KOH-> C2H5OH+ KCl.
C2H5OH  ----KMnO4 ---> CH3COOH.

How is clayey soil useful for crops?
joja [24]

Answer:

Clayey soil is rich in humus and very fertile, so it is suitable for growing cereals like wheat and gram. Such soil is good at retaining water.Clayey is known to be useful for crops. Because the particle size in this soil is very fine, it has the ability to retain more amounts of water. - This makes it easy for crops to access water as it is very essential for the growth of the plant. - Some of the crops need a high amount of water in order to grow.Clayey soil is made up of fine particles that are tightly packed and increases soil density and strength. It is rich in nutrient content in the form of organic matter or humus so, it is very fertile soil. It has excellent water retaining a capacity.
