You neutralize 275.0 mL of a 6.00 M hydrobromic acid solution with 150. grams of baking soda (solid sodium bicarbonate). Show all work for every part of this problem, including dimensional analysis, sig figs and units!  Highlight your answer in a readable background color.   A.  (2 pts) Write the balanced molecular equation for this reaction, including states of matter. B.  (4 pts)  Determine the limiting reactant. C.  (6 pts)  What volume (in L) of dry carbon dioxide gas (no water vapor will collect with the CO2) will be produced if the CO2 gas is at 777 torr partial pressure and 32.1°C?  Assume 100% yield. D.  (4 pts)  What volume (in mL) of liquid water is produced by this reaction?  Assume 100% yield, and that the density of water is 0.997 g/mL.

3.0 moles of N2 gas are placed inside of an empty balloon.  6.0 moles of O2 gas are then placed inside of the same balloon, which has now doubled in volume compared to when it contained only the N2 gas.  The temperature of the balloon has not changed.  Which of these statements is most likely to be true?
