Answer is: <span>the enthalpy for reaction 1 reversed is 1370 kJ/mol.
</span><span>Balanced chemical reaction 1:
C</span>₂H₅OH + 3O₂ → 2CO₂ + 3H₂O ΔrH<span>= -1370 kJ/mol.
</span>Reaction 1 is exothermic reaction (heat is released), than reversed reaction is endothermic (<span>chemical reaction
that absorbs more energy than it releases) and has same value for enthalpy, but positive sign.</span>
They act together to neutralise each other. this reaction realeases carbon dioxide and the baking soda freezes in the ice.

Answer:
b. electronegativity
Explanation:
The ability of an atom in a molecule to attract electrons is best quantified by the _Electronegativity_.
Electronegativity is the ability of an atom to attract a shared pair of electron which is loosely held. Polar molecules often possess such properties. The Halogen group (group 17) is famous for such property because it has the highest electronegativity in periodic table.
