Reaction equation:
Al(OH)₃ + 3HCl → AlCl₃ + 3H₂O
Moles of Al(OH)₃:
moles = mass/Mr
= 1.51 / (27 + 17 x 3)
= 0.019
Molar ratio Al(OH)₃ : HCl = 1 : 3
Moles of HCl required = 0.019 x 3
=0.057
concentration = moles/volume
volume = 0.057 / 0.1
= 0.57 dm³
= 570 ml
Among the elements Barium has the lowest Ionization Energy.
<h3>What is Ionization Process ?</h3>
The process by which any neutral atom gets converted into electrically charged by gaining or losing electron is called Ionization Process.
K is an alkali metal it has to lose one electron to attain stable electronic configuration of an inert gas
For removing second electron , a stable configuration has to be broken and so will require high amount of energy.
Ca and Ba are alkaline earth metals.
They both have to lose 2 electrons to attain stable electronic configuration of noble gas.
They have low Iow Ionization Energy as compared to K.
Ca has higher Ionization Energy as compared to Ba because when we move down the periodic table , The ionization energy decreases.
Hence , Among the elements Barium has the lowest Ionization Energy.

Answer:
It means to be included in something, such as a group or activity.
Explanation:
1 grams F2 to mol = 0.02632 mol
10 grams F2 to mol = 0.26318 mol
20 grams F2 to mol = 0.52636 mol
30 grams F2 to mol = 0.78954 mol
40 grams F2 to mol = 1.05272 mol
50 grams F2 to mol = 1.3159 mol
100 grams F2 to mol = 2.6318 mol
200 grams F2 to mol = 5.2636 mol
Organic chemistry was definitely harder for me, though this is a matter of opinion and learning style. If you are good with logic, then organic chemistry might not be so hard, or at least that's what my professor said. A lot of physics was just knowing how to use formulas and then plugging and chugging, and knowing basic outcomes of physical reactions. It's a whole other story if you take calculus based physics.
Good luck.
