What will oxygen likely do to complete its outermost shell, based on the Lewis dot diagram shown?
accept electrons
accept some electrons and give up other electrons
move electrons from the inner shell to the outer shell
give up electrons
Answers
Answer:
A. Accept electrons
Explanation:
The octet rule states that 8 electrons stabilizes a molecule. This means that oxygen will try to fill the two empty spots with electrons from other molecules. The Lewis Dot diagram shows these two empty spots with the empty circles at the bottom.
Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Here 'O' accepts electrons. The correct option is A.
The electrical structures of the elements, especially the electron pairings, are reflected in the Lewis dot structures. Lewis structures can be viewed as "electron bookkeeping" and are a helpful approach to condensing some bonding-related information. Each dot in a Lewis dot structure corresponds to 1 electron.
Group 6 member oxygen still requires two additional electrons to complete its outer shell and remain stable. According to the octet rule, an object needs 8 valence electrons in the outer shell to be stable.
Thus the correct option is A.

As you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What two processes did you observe?
Answers
Answer:
Weathering and erosion
Explanation:
Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors
. There are 3 common types of weathering which are;
1) physical weathering
2) biological weathering
3) chemical weathering
Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.
Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.
After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks

A only when melted
B. when melted or dissolved in water
C. only when it is in crystal form
D. only when dissolved
Answers
Answer:
potassium bromide can only conduct electricity when in an aqueous solution due to the electrostatic force between the ionic bonds
The potassium bromide can conduct electricity when melted or dissolved in water. Therefore, option (B) is correct.
What are ionic compounds?The crystalline solids which are formed by closely packed ions of opposite charge are called ionic compounds. In ionic compounds, the ions are connected with each other by ionic bonds in solis state.
The elements which can gain or lose electrons to attain their nearest noble gas configuration participate in the formation of ionic compounds. The solid ionic compound cannot able to conduct electricity.
In the melted state, the ions of K⁺ and Br⁻ can move from their fixed positions. Therefore, the KBr can conduct electricity when melted or dissolved in water.
The ionic compounds are able to conduct electricity in melted or dissolved in water. Because only in these states the ins can move freely while in the crystalline state the ions cannot move freely to conduct electricity.

Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm long. What is the length of the bacteria written in scientific notation?
Answers
Answer:
[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]
Explanation:
Aly's teacher said some bacteria can be as small as 0.00365 cm long.
In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :
[tex]N=a\times 10^b[/tex]
a is a real no and b is an integer
In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :
[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]
Hence, this is the required solution.

Initial pressure = 157 kpa (Approx)
Explanation:
Given:
final temperature = 234 K
final pressure = 210 kpa
Initial temperature = 175 K
Find:
Initial pressure
Computation:
Initial pressure / Initial temperature = final pressure / final temperature
Initial pressure / 175 = 210 / 234

Which characteristic is related to kinetic energy but not potential energy
Answers
Answer:
kinectic is movement and potential is still
Explanation:
While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.
Answer:an object’s speed

with anything. After 3 hours, the
number of mosquito bites is counted. What is the control group
Answers
Answer:
The arm that was not sprayed with anything
Explanation:
The control group would be the arm that was not sprayed with anything.
The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.

12. If the particles of a liquid are always moving, why don't they all come apart from each other and become a gas?
Answers
Answer:
even though the particles of a liquid are moving, they are attracted to each other so they don't spread far apart to become a gas.
Explanation:
"but some do when they evaporate"
In liquids, the particles are allowed to move freely rather than the solid. The gaseous particles can move more freely than liquids.
Particles in liquids:In liquids, the particles are placed randomly and thus are allowed to move freely but they do not become a gas as liquids are slightly less compressible than gases. Even though the particles of a liquid are moving, they are attracted to each other so they don't just spread far apart to become a gas.

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options: True False
Answers
Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
Electromagnetic waves are waves that do not require a material medium for their propagation. They are able to pass through vacuums and mediums with particles at constant speed. It is mechanical waves whose speed is medium dependent. Mechanical waves have varying speed based on the mediums they move through.How is kinetic energy of particles and temperature related
