The atomic radius of a chemical element is a measure of the size of its atom.
The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.
The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
Phosphoric acid or orthophosphoric acid (H₃PO₄) is triprotic acid, which means it lose three protons in chemical reaction (in reaction of esterification with alcohol) and sulfuric acid (H₂SO₄) is diprotic acid, which means it lost two protons in chemical reaction and does not have enough palce to bind alcohol.
Answer:
1 mol
Explanation:
Using the general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the provided information in the question;
V = 22.4L
T = 273K
P = 1 atm
R = 0.0821 Latm/molK
n = ?
Using PV = nRT
n = PV/RT
n = (1 × 22.4) ÷ (0.0821 × 273)
n = 22.4 ÷ 22.4
n = 1mol
Answer:
The element is Aluminium. (assuming that the given quantum number set is for the valence electron of the unknown element)
Explanation:
The given quantum numbers are:
n=3 (Principal Quantum Number)
l=1 (Azimuthal Quantum Number)
m=0 (Magnetic Quantum Number)
s= -1/2 (Spin Quantum Number)
The given set of quantum numbers refer to the 3p orbital.
Assuming that this the valence electron of the element, the unkown element is Aluminium.
