The combustion of 1.760 g of propanol (C3H7OH) increases the temperature of a bomb calorimeter from 298.00K to 302.15K. The heat capacity of the bomb calorimeter is 14.24 kJ/K. Determine ΔH for the combustion of propanol to carbon dioxide gas and liquid water in kJ/mol.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
