Answer:
I believe its radiant energy.
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.
Well, the element of hydrogen only has 1 electron in its s sub shell, if it's s sub shell for the energy level of 1 were to be filled, there would need to be 2 electrons present in its shell to have a full first shell, as the s sub shell can only hold 2 electrons within it.
A because dormant volcanoes are volcanoes that have not erupted in a long time but are expected to erupt again in the future
There is a shortcut to this Chem question. simply look at this problem as if it were a cooking recipe. you have 7 parts Carbon and 18 Parts Hydrogen for a total of 25 parts. Simply divide 5.2 by 25 then multiply by 7 to get your answer.
(5.2/ 25) 7 = 1.456 moles
