Answer:
Explanation:
Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.
In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.
B) noble gases
C) alkali earth metals
D) alkaline earth metals
The most stable because they can contain the most valence electrons in their outer shell. The correct option is B.
Thus, The group of elements on the periodic table known as noble gases, commonly referred to as inert gases, is thought to be the most stable.
They are radon (Rn), krypton (Kr), xenon (Xe), neon (Ne), helium (He), and argon (Ar). Noble gases are extremely stable and less likely to combine chemically with other elements because they contain entire valence electron shells.
Their full electron configurations, which result in low reactivity, are the cause of this stability.
Thus, The most stable because they can contain the most valence electrons in their outer shell. The correct option is B.

A)The temperature of the balloon
B)The diameter of the balloon
C)The amount of air
D)The three balloons
To solve this we must be knowing each and every concept related to experiment. Therefore, the correct option is option B among all the given options.
An experiment is a qualitative approach used in the scientific process to settle disputes between competing products or hypotheses. Additionally, experiments are used by researchers to confirm or refute new or existing theories.
A student designs an experiment where she will put the same amount of air into three different balloons. One balloon will be submerged in ice water, one balloon will be carefully heated with a hair dryer, and the last balloon will be left alone. After making the changes, the student then will then measure the diameter of each balloon. The dependent variable is the diameter of the balloon.
Therefore, the correct option is option B.

Answer:
B
Explanation:
A fundamental object that is difficult to divide into smaller bits is known as an element. An element is a substance that cannot be broken down by non-nuclear reactions in chemistry and physics. The elements are boron and oxygen, and their numbers are 1 and 2.
A pure material known as an element is made up of just one type of atom and cannot be divided into two or more different substances. A compound is a pure substance that is created when two or more substances are mixed in a specific mass ratio.
Chemistry's fundamental building block is an atom. It is the smallest fraction of matter into which electrically charged particles cannot be released. It is also the smallest piece of substance with chemical element-like characteristics.

Nitrogen gas consists of a molecule of two nitrogen atoms, known as a nitrogen-nitrogen triple bond, making it stable and unreactive. Diatomic nitrogen atoms or compounds of nitrogen atoms are not correct representations of nitrogen gas due to the bonding and structure of nitrogen gas.
Nitrogen gas consists of a molecule of two nitrogen atoms. In this molecule, the two nitrogen atoms are bound together in what is known as anitrogen-nitrogen triple bond, which is very strong. This is why nitrogen gas is very stable and unreactive under normal conditions.
Therefore, a diatomic nitrogen atom or a compound of nitrogen atoms is not a correct representation of nitrogen gas because these expressions do not accurately reflect the bonding and molecular structure of nitrogen gas.
