A. Which way should the equilibrium shift when Na2SO4 is added? How do your results support your answer?
It should shift to the left because adding any component causes the equilibrium to shift to the opposite side.
B. Which way should the equilibrium shift when NAHSO4 is added? How do your results support your answer?
It should shift to the right because the removal of a component causes the equilibrium to shift to the side from which the component was removed.
C. Is this reaction endothermic or exothermic? How do you know?
If 147 g of CaO and 267 g of NH4Cl are mixed, what is the maximum possible yield of NH3?
Consider H2, D2, and H20, treated as ideal gases at pressures of 1 atm and temperatures of 293.2 K.
30.0 mL of water at 24.5 °C was mixed with 40.0 mL of water at 40.0 °C. If the specific heat of water is 4.184 J/g °C and no heat was absorbed by the calorimeter, then the final temperature is _____ °C. (Report to the proper number of significant ..
A gas is heated from 269 K to 283 K while its volume is increased from 21.5 L to 37.0 L by moving a large piston within a cylinder. If the original pressure was 1.10 atm, what would be the final pressure?
What is the de Broglie wavelength of a 11.5 g hummingbird flying at 109 mph?
