Calculate ΔH° = for the chemical reaction

Chemistry

Answer: \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

Explanation:

The balanced chemical reaction is,

The expression for enthalpy change is,

\Delta H=[n\times B.E_{reactants}]-[n\times B.E{products}]

where, n = number of moles

Now put all the given values in this expression, we get

\Delta H=[1\times B.E_{Cl_2}+1\times B.E_{F_2}]-[2\times B.E_{ClF}]

\Delta H=[(1\times 243)+(1\times 159)]-[2\times 255]

\Delta H=-108kJ

Thus \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

Hydrogen ions cannot exist alone but they exist after combining with water molecules true or false​
juin [17]
True because hydrogen ions combines with h2o to make hydronium ion, so in a sense h2o is acting like a base.
