The ability to conduct electricity in the solid state is a characteristic of metallic bonding. this characteristic is best explained by the presence of: ) high ionization energies.
(b) high electronegativities.(c) mobile electrons.
(d) mobile protons.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

i'm pretty sure its b i might be wrong though!

the answer is barium and copper bromide
