is −772 kJ, what is the ΔH for this reaction:
2NaCl → 2Na + Cl2

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

the dissolution of polymer can be thermodynamically described in 2 steps.
