NISA [10]

Answer:

The products are: KCl03 and H20.

Explanation:

The reaction between HC03 (chloric acid) and KOH (potassium hydroxide) is:

HC03  + KOH ----> KCl03 (KCl03 and H20) + H20 (water)

<em></em>

<em>The reaction is of the double displacement type (in this case parts of the reagents are exchanged, producing two generating new compounds).</em>

The synthesis of CH3OH from CO and H2 is represented by the equation below.
sergij07 [2.7K]

Answer: Option (b) is the correct answer.

Explanation:

In a chemical reaction, the bonds between the reactant molecules tend to break leading to the formation of new bonds to produce products.

So, in order to break the bonds between the reactant molecules, energy is required to overcome the attraction between the atoms.

To form new bonds, energy gets released when two atoms come closer to each other.  Hence, formation of bond releases energy.

As in the given reaction it is shown that \Delta H < 0, that is, enthalpy change is negative. Hence, energy is released as it is an exothermic process.

Thus, we can conclude that the statement energy released as the bonds in the reactants is broken is greater than the energy absorbed as the bonds in the products are formed, is true about the bond energies in this reaction.
