Q:

The reactivity of an atom arises from 

A) the existence of unpaired electrons in the valence shell B) the energy differences between the electron shells
C) the sum of the potential energies of all the electron shells D) the average distance of the outermost electron shell from the nucleus
 
Answer & Explanation Answer: A) the existence of unpaired electrons in the valence shell

Explanation:

When atoms react they do so in order to reach the lowest energy, which is the most stable. The electrons orbitals will overlap in the way that reduces the energy the most. Orbitals of similar energy will produce the greatest stabilisation.The answer you gave isn't the whole story, it depends what species is reacting with what. The effective nuclear charge on the atom will affect the energy of the valance electrons.

 

Hence, the reactivity of an atom arises from the existence of unpaired electrons in the valence shell.

Q:

Water is an example of?

A) Element B) Molecule
C) Compound D) Both B & C
 
Answer & Explanation Answer: D) Both B & C

Explanation:

Why Water Is Not an Element :

An element is a substance consisting of only one type of atom. Water consists of two types of atoms: hydrogen and oxygen.

 

water is both a molecule and a compound :

A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms.

Thus, water is a compound.

 

It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms molecule and compound mean the same thing and can be used interchangeably.

 

Hence, water is both a molecule and a compound.

Q:

What does the judicial branch do?

Answer

The United States government has 3 branches, which all serve an important role in running the government and keeping our system of laws in place.


 


1. The legislative branch


2. The executive branch 


3. The judicial branch


 


The legislative branch makes the laws while the executive branch enforces these laws. 


The judicial branch is a system of courts that applies the laws.


 


Both the federal government and each of the 5 states have individual judicial branches which all serve this purpose.


 


For example :: 


If the federal government were like a basketball game, the judicial branch is much like the referee that helps settle disputes. The executive branch and the legislative branch are often like the players in the game trying to score points against each other, and the judicial branch is there to clarify the rules and make sure each side is acting fairly.
