MAGNESIUM(Mg) posses the up mentioned electronic configuration
Answer:
n = 2 mol
Explanation:
Given data:
Pressure = standard = 1 atm
Temperature = standard = 273.15 K
Volume = 44.8 L
Number of moles = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × 44.8 L = n × 0.0821 atm.L/ mol.K × 273.15 K
44.8 atm.L = n × 22.43 atm.L/ mol
n = 44.8 atm.L / 22.43 atm.L/ mol
n = 2 mol
Answer:
number of valence electrons
Explanation:
All of the elements in group 17, also known as group 7A, have 7 valence electrons.
No two elements have the same atomic number nor atomic mass in elemental form.
Halogens may have any number of isotopes.
Correct compound is [Co(H2O)6]^+3
The oxidation state of Co is +3
[Co(H2O)6]^+3
Let
Co be x
H2O = 0
x + (0)6 = 3
x = 3
What is oxidation state?
The oxidation state, commonly known as the oxidation number, is the potential charge that an atom would have if all of its bonds to other atoms were fully ionic. It describes the degree of atom oxidation within a chemical compound.The oxidation state may be positive, negative, or zero in theory.
The oxidation number, sometimes referred to as the oxidation state, is the total number of electrons that an atom gains or loses while uniting with another atom to form a chemical bond.

Slow cooling of magma results in the formation of c. coarse-grained textured rocks. An example of a coarse grained textured rock formed in this fashion is granite. As the rate of cooling of igneous rocks increases, the size of the crystal that is formed decreases. The Bowen's reaction series shows the different rocks cooled at different rates.
