Answer: The Ionization energy of Barium is lower and hence it can lose its electrons easily.
Explanation:
Ionization energy is defined as the energy required to remove an electron from an isolated gaseous atom. It is represented as 
This energy will be higher for fully filled and half-filled electronic configuration than partially filled electronic configuration. This is so because half filled and fully filled configurations are stable.
Magnesium is the 12th element of the periodic table having electronic configuration of = ![[Ne]3s^2](https://tex.z-dn.net/?f=%5BNe%5D3s%5E2)
Barium is the 56th element of the periodic table having electronic configuration of ![[Xe]6s^2](https://tex.z-dn.net/?f=%5BXe%5D6s%5E2)
Both magnesium and barium belong to the same group as they have similar valence electrons. But as Barium is larger in size, the valence electrons lie farther from the nucleus and lesser energy is required to remove the electron and thus ionization energy will be lower for barium and thus will be more reactive.
Answer:
The correct answer is B) They created new treaties and reservations that defined specific boundaries for each tribe
Explanation:
One of such acts which was used to reallocate the Native American Land was the General Allotment (Dawes) Act of 1887.
It gave permission to the Federal Government to modify the size and ownership structure of land belonging to the Native Americans. The end result was that the total amount of land originally belonging to the Native Americans reduced drastically over the next 500 years.

An hypothesis is the proposed explanation that is made on the basis of limited evidence and it serves as the starting point for further investigation while a problem statement is a clear, concise description of the problems which needs to be addressed.
Problem statement is used to concentrate the focus of the researcher at the beginning, to keep him on track during the operation and at the end it is used to evaluate if the process delivered an outcome that solve the problems.
Hypothesis is used to define the relationship between two variables at the end of the research the scientist has to decide when its starting hypothesis is valid or not.<span />
The solution for this problem is:
Let x denote the specific rotation, R; andLet y denote the specific rotation, S = -x
Solution:60 x - 40 x/100 = - 43
20x = - 4300Divide both sides by 20The answer is:x = - 215 is the specific rotation of the pure r isomer.
