Answer : To determine enthalpy of solution for a solid with δH values.
One can use the equation as H (reaction) = H (products) - H (reactants)
If δH values are known one can simply substitute them in the above equation and get the enthalpy of the required solution.
Answer:
Explanation:
Of all the given forces , london dispersion force is the weakest inter-molecular force which is temporary in nature . This force results due to two adjecent atoms or molecules becoming dipoles temporarily. This force exists among the atoms of inert gases.
Atoms having this force have lowest boiling point.
When electrical power is applied to two plates placed inside the water, electrolysis occurs and hydrogen appear on the cathode and Oxygen on anode. It is due to the ideal faradaic efficiency, the amount of hydrogen generated is twice the number of moles of oxygen.
If you look at the equation , reduction occurs at cathode i.e
2 H+ + 2e−<span> → H</span>2
Oxidation occurs at anode
2 H2O → O2 + 4 H+ + 4e<span>−
</span>
Overall reaction
2 H2O(l) → 2 H2(g) + O2(g<span>)
Therefore, </span><span> volume of gas collected over one electrode double the volume of gas collected over the other electrode.</span>
