Answer:
21.60% is the percent ionization of a 0.123 M solution of this acid.
Explanation:
The equilibrium reaction for dissociation of weak acidis,
initially conc. c 0 0
At eqm. 
Concentration of the weak acid (c) = 0.123 M
Acid dissociation constant = 
Degree of ionization of weak acid = 
An expression of dissociation constant is given as:
Percent ionization of weak acid:
Pretty sure it would be formula
Answer:
13 protons, 10 electrons, 14 neutrons
Explanation:
First, Al is having a charge of +3, and this means Al has lost 3 of its valence electrons.
Neutral atom of Al has atomic number of 13, but this isn't an atom. This is an ion which has lost 3 electrons, therefore the number of electrons becomes 10 while the number of protons remains 13.
We get the number of neutrons by subtracting the number of protons from the mass number. In this case, the mass number is 27 and proton number is 13. If you take away 13 from 27, you are left with 14. This is the number of neutrons.
<h2>Nucleosynthesis.</h2>
Explanation:
A. the Big Bang occurred; the Big Crunch occurred
Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.
According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.
The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end. A
