Write and balance the chemical equation for the reaction associated with ΔHof of NaN3(g). What is the sum of all of the coefficients in your balanced chemical equation? (Ex: the answer would be 5 for the reaction: 2 CO + O2 -> 2 CO2)

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.
