A 1.00 liter solution contains 0.50 moles nitrous acid and 0.38 moles sodium nitrite. If 0.19 moles of hydrobromic acid are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of hydrobromic acid.) @A. The number of moles of HNO2 will increase. B. The number of moles of NO, will decrease. E C. The equilibrium concentration of H30+ will remain the same. BD. The pH will increase. 8 E. The ratio of [HNO2]/[NO2) will remain the same.

A 1.00 liter solution contains 0.38 M ammonia and 0.29 M ammonium bromide. If 0.15 moles of hydrochloric acid are added to this system, indicate whether the following statements are true or false.
