Answer:
C) is less than 7
Explanation:
The dissociation constant, Ka of nitrous acid, HNO2 = 4.5 * 10^-4
Ammonia, NH3, is a weak base with a Kb value of 1.8x10^-5
When a weak acid like HNO2 reacts with an equivalent amount of a weak base NH3, complete neutralization does not occur. The concentrations of the species in equilibrium with each other will depend on the equilibrium constant, K, for the reaction,
Since the dissociation constant, ka of nitrous acid is higher, at equivalence point the pH of the solution will be slightly acidic with a pH that is less than 7.
Gold has 79 protons on the periodic table
Answer:Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
The constant use of water flow throwout nature and the way that we use it now isint good and most likly we will be out of water by the year 2055
