1. The conjugate acid-base pairs are HCl/Cl- and NH3/NH4+. They can be changed into one another by proton transfer.
2. The acid in the reaction is the molecule that has the lowest pKa value or (simply) gives their proton away the easiest. The pKa of HCl is around 3 I think while ammonia’s is around 35. This means HCl is the acid here. In the other reaction (backwards) you can see that NH4+ gives a proton to the chloride ion. To give a proton = acid. So the acids are HCl and NH4+ and the bases are NH3 and Cl-.
An important rule is: The stronger the acid/base, the weaker its conjugate base/acid.
First off, what is nonpoint-source pollution?
It comes from many sources BUT this type of pollution doesn't come from factories discharging their waster, nor sewage pipes, nor smokestack emissions; but rather it comes from rainfall or snow-melt moving through and over the ground. Taking away natural and human-made pollutants.
This being said, the answer, is A. Polluted Rainwater.
Answer:
15:37
Explanation:
cant simplify because 37 is prime
Answer:
C is the answer!
Explanation:
temperature is a measurement of the average kinetic energy of the particles in an object
A. there will be less pollution.
b. less machinery=hiring workers=jobs.
c. If farm machinery broke in the field. repairing is very inconvenient. There will be no trailer to pull it away. This is a disadvantage of machinery.
