Answer:
The correct answer is - due to the movement of plates it is relocated.
Explanation:
Antarctica is a very cold part of the earth, it is so cold that there is no growth of trees or such vegetation. Even though there are no or less vegetation scientists found fossils of the trees.
It is relocated from the north where the conditions were warmer and easy for tree growth. It is then moved due to plate movements to the south pole. This is the reason behind the fossils scientist found.
Answer: Vanadium -23 has an electronic configuration of
[Ar]3d3 4s2 (e)
Explanation:
Vanadium has an atomic number of 23 . The total number of electrons in all the subshells will also be 23 .
For (a) [ Ar] has an 18 electrons already, adding 2 from 3s subshell 7 from 3p subshell makes it 27 electrons which is greater than 18. Also, it doesn't conform with the rule of electronic configuration.
(b) [ Ar] has an 18 electrons already, adding, adding 4 from 3s orbital and 5 from 3p orbital makes it 27 which is greater than 23.
(c) [ Ne] has an 10 electrons already, adding, 3 from 3s and 3 from 3p makes it 16. Which is less than 23
(d) [ Ne] has an 10 electrons already, adding, 4 from 3s and 1 from 3p makes it 14 . Which is less than 23.
(e)[ Ar] has an 18 electrons already, adding, 3 from 3d subshell and 2 from 4s subshell makes it 23.
Therefore [Ar]3d3 4s2 is the condesed electronic configuration of Vanadium.
Answer: Balanced chemical equation will be :

Explanation:
(Unbalanced)
A balanced chemical reaction follows the Law of Conservation of Mass. which states in a chemical reaction mass can neither be created nor be destroyed. In other words total mass of the products is equal to the total mass of reactants.
Balanced chemical equation will be :

Answer:
The mass in grams of N₂O gas that can be dissolved is 0.18 g
Explanation:
The solubility of a gas is proportional to the partial pressure of that gas, over a determined solvent. That's what Henry's law states. We see the formula:
S = K . Pp
Where S is solubility and K is Henry's constant. This specific for each gas and each temperature, while Pp means partial pressure.
We replace data:
S = 0.025 M/atm . 0.69atm
S = 0.01725 M
This is the solubility of the gas, so now, we need to know what mass of gas is solubilized. We convert the moles, with the volume of water.
0.01725 mol/L . 0.235 L = 4.05×10⁻³ moles
Now, we determine the mass in grams: 4.05×10⁻³ mol . 28 g / 1mol =
0.1782 g
