D) basic ions contain some H+ ions
Answer:
v = 1130 cm³
Explanation:
Given data:
Volume of sample = ?
Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)
Density of Al sample = 2.70 g/cm³
Solution:
Formula:
d = m/v
d = density
m = mass
v= volume
by putting values
2.70 g/cm³ = 3057g /v
v = 3057g /2.70 g/cm³
v = 1130 cm³
Explanation:
The number of orbitals in the sublevels are given below:
Sublevels Orbitals
s 1
p 3
d 5
f 7
a. ls - 1 orbital
b. 5s - 1 orbital
c. 4d - 5 orbitals
d. 4f - 7 orbitals
e. 7s - 1 orbital
f. 3p - 3 orbitals
g. Entire 5th principal energy level : for s, p , f
1 + 3 + 5 + 7 + 9 = 25
h. 6d - 5
