If the enthalpy change for the combustion 2.00 g of propane, c3h8, was determined to be −102.5 kj by calorimetry, what is the calculated enthalpy change for the combustion of one mole of propane under the same conditions?

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
