Answer:
yes
Explanation:
because is smallest element that are made up of atom
Explanation:
The given data is as follows.
= 2.34 kPa = 2.34 \times 1000 Pa = 2340 Pa = 0.0231 atm
= (20 + 273) K = 293 K
= 2537.4 kJ/kg = 2537400 J/kg
= ?, = (40 + 273) K = 313 K
According to Clausius-Clapeyron equation,
=
=
= atm
or, = 18846.45 kPa
Thus, we can conclude that the vapor pressure at is 18846.45 kPa.
Eu2+ is stable because of the two electrons in its outermost orbit and after losing 4 electrons. Ce +4 is stable
What are lanthanide ions?
All lanthanide elements form trivalent cations, Ln3+, whose chemistry is largely determined by the ionic radius, which decreases steadily from lanthanum to lutetium. These elements are called lanthanides because the elements in the series are chemically similar to lanthanum.
The Ce metal has the following electronic configuration: [Xe] 4f¹5d¹6s²
It obtains noble gas configuration after losing 4 electrons. Ce +4 is stable, so.
Eu's electronic setup is as follows.
[Xe] 4 f ⁷6s²
[Xe] 4 f ⁷
Eu2+ is stable because of the two electrons in its outermost orbit. Additionally stable is its +3 oxidation state. Ce⁺²

Answer:
Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae. They also make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities.
Example... H+O2------>H2O
