A strong base will always completely dissociate in water to produce hydroxide ions. Strong bases have a high pH and are able to accept protons from acids to form water.
A weak base will always partially ionize in solution and generate fewer hydroxide ions compared to a strong base. This means that a weak base will have a lower pH compared to a strong base at the same concentration. Weak bases also have higher Kb values compared to strong bases.
Some of the original base remains in the solution

No, ammonia is only evolved when an ammonium salt is heated with a strong base, such as sodium hydroxide. This reaction occurs because the strong base deprotonates the ammonium ion, leading to the formation of ammonia gas.
Yes, the conjugate base of a strong acid is typically a weak base because strong acids fully dissociate in solution, leaving behind a neutral species that does not readily accept protons to act as a base.

The base angles are always congruent.

In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.

A weak base is a substance that partially dissociates in water to produce hydroxide ions. It has a lower tendency to accept protons compared to a strong base, resulting in a higher equilibrium constant for the reverse reaction. Weak bases typically have a low pH value when dissolved in water.
b) The conjugate acid of a weak base is a weak acid. When a base accepts a proton to form its conjugate acid, it tends to be a weak acid because it does not easily donate a proton back. This relationship is governed by the principles of acid-base equilibrium.
That's true if the exponent is zero. Then it doesn't even matter what the base is.
