When 0.25 g of the organic compound naphthalene are burned in a bomb calorimeter, the temperature of the water in the calorimeter increases from 24.00°C to 26.43 °C. The calorimeter's heat capacity is 4.13 kJ/°C. How much heat (9rxn) in kilojoules is
released by the combustion of the naphthalene?

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.

hope this !

and sorry if i'm late. have a good rest of your day! : d
