A 1.27-g sample of fumaric acid (C4H4O4) is burned in a bomb calorimeter and the temperature increases from 24.70 °C to 27.50 °C. The calorimeter contains 1.01×103 g of water and the bomb has a heat capacity of 755 J/°C. Based on this experiment, calculate ΔE for the combustion reaction per mole of fumaric acid burned (kJ/mol).

Consider the following equilibrium: N₂ (g) + 3H₂(g)2NH₂ (g) AG = -34. KJ 2 Now suppose a reaction vessel is filled with 3.70 atm of hydrogen (H₂) and 8.46 atm of ammonia (NH3) at 1099. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of H ₂ tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding N₂? x Ś ? In other words, if you said the pressure of H₂ will tend to rise, can that be changed to a tendency to fall by adding N₂? Similarly, if you said the yes no pressure of H₂ will tend to fall, can that be changed to a tendency to rise 2 by adding N₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of N₂ needed to reverse it. atm Round your answer to 2 significant digits. ● O
