Answer:
Answer:
B. It's dissociation is a reversible reaction
Explanation:
NH3 is a weak alkali that does not dissociate fully into its solution. Only parts of the ammonia takes part in the dissociation process.
NH3 + H20 —> NH4+ + OH-
This dissociation is reversible which means the reactants can be formed from the product gotten from the dissociation
It has a high pH due to its basic nature. It also has a Low concentration of H+ ions and not all the OH- ions are released.

The mass in kg of the water on the roof after the rainstorm is mathematically given as
The mass of the water on the roof after a rainstorm is 1.1 *10^{10}g or 1.1*10^{7}kg
<h3>What is the mass in kg of the water on the roof after the rainstorm? </h3>
Generally, the equation for the Area of the roof is mathematically given as

height of the rain =5.5cm
the volume of the rain on the roof =1.1 * 10^{10} CC
Generally, the equation for mass is mathematically given as
mass=volume*density

In conclusion, the Mass of the water on the roof after a rainstorm is 1.1 *10^{10} or $1.1*10^{7}
