Want to know:
(FUVEST) Os hidrocarbonetos isômeros antraceno e fenantreno diferem em suas entalpias (energias). Esta diferença de entalpia pode ser calculada, medindo-se o calor de combustão total desses compostos em idênticas condições de pressão e temperatura. Para o antraceno, há liberação de 7060 kJ/mol e para o fenantreno, há liberação de 7040 kJ/mol.Sendo assim, para 10 mols de cada composto, a diferença de entalpia é igual aa) 20 kJ, sendo o antraceno o mais energético.b) 200 kJ, sendo o fenantreno o mais energético.c) 20 kJ, sendo o fenantreno o mais energético.d) 2000 kJ, sendo o antraceno o mais energético.e) 200 kJ, sendo o antraceno o mais energético
