The answer is NH3 an NH4+.
Buffer solutions contain a weak base and its conjugate acid or a weak acid and its conjugate base. NH3 is a weak base and NH4+ is its conjugate acid.
Answer:
A 25% of the initial parent nuclei.
Explanation:
One half life, you get 50%, two half lives you get 25% and you just keep dividing by 2 from there. :) Good luck my friend!
Answer:
It's A
Explanation:
It starts as one molecule and splits into two which is the definition of a decomposition reaction
A. weathering, transport, and deposition.
Explanation:
Water running downhill is an example of external force that shapes the landform on the earth surface.
Water is an important agent of denudation which plays a key role in scultpting the surface.
The action of running water downhill:
- Leads to weathering of the slopes by chemical and physical disintegration of the rock mass.
- The weathered materials are carried by the water and deposited at the foot of the hill.
- The process completes denudation.
- Denudation is the shaping of the earth surface through the action of wind,water, glacier and gravity.

This problem is asking for the rate of disappearance of gaseous nitrogen, given the rate of appearance of ammonia and the chemical reaction. At the end, the result turns out to be -0.228 M/s.
<h3>Rates of appearance and disappearance</h3>
In chemical kinetics, one of the most relevant calculations are based on rates of appearance and disappearance of chemical species in a chemical reaction. This can be calculated via rate portions based on the stoichiometric coefficients in the reaction.
Thus, for this problem, one can write:
Where the rate of appearance or disappearance is divided by the stoichiometric coefficient. Therefore, one can solve for the rate of disappearance of N2 with:
