Explanation:
the moon is still volcanic
The transition metals is Group 3B(13), there is a smoother decrease in ionization energy because these group contains only the transition metals.
The quantity of strength needed to remove an electron from a selected gaseous atom or ion is called the ionisation electricity Group 3B(13) . not just the atoms that are gases at ambient temperature are protected via it; all the elements at the periodic desk are included.
Ionization energy:
the desired energy to put off an outermost electron from a neutral atom is known as ionization electricity.
In typically, up to down inside the periodic table ionization power is decreases but in group 3A and Group 3B(13) (thirteen) it's miles irregular because the arrival of the transition metals in four length due to this Ga, In and Tl elements indicates better the ionization energies so there's no pattern on this organization.

Answer:

Explanation:
Mass of water molecule = mass of hydrated salt - mass of anhydrous salt
Mass of water molecule = 5.00 - 4.26 = 0.74g of water molecule.
Number of moles = mass / molarmass
Molar mass of water = 18.015g/mol
No. of moles of water = 0.74 / 18.015 = 0.0411 moles.
Mass of BaCl2 present =?
1 mole of BaCl2 = 208.23 g
X mole of BaCl2 = 4.26 g
X = (4.26 * 1) / 208.23
X = 0.020
0.020 moles is present in 4.26g of BaCl2
Mole ratio between water and BaCl2 =
0.0411 / 0.020 = 2
Therefore 2 molecules of water is present the hydrated salt.
