Answer:
C. New ocean crust forms.
Explanation:
At divergent margins, it is true that new ocean crusts forms at the margins.
Along a divergent margin, two lithospheric plates are moving apart from one another.
Usually, when this occurs between two oceanic plates, the underlying mantle upwells to fill the void. The cooling and solidifying mantlic materials furnishes the formation of a new crust.
This is the oceanic crust.

How do the two desalination processes differ from the atmospheric water generator in terms of where the processes can be used?
Answer:
Water Desalination Processes. Water desalination processes separate dissolved salts and other minerals from water. Feedwater sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor)
Explanation:
Salinized water cannot be consumed by humans, but it can be converted into freshwater, which has a variety of purposes. Desalination is the procedure, and it is being employed increasingly frequently all over the world to supply people with the freshwater they require.
What is desalination process?Desalination is the procedure used to remove the dissolved mineral salts from water. Currently, one of the most popular methods for obtaining fresh water for use in agriculture or human consumption when applied to seawater.
When seawater evaporation occurs, salt is left behind, and clouds are formed, which eventually result in rain. Da Vinci realised that it was easy to obtain using a still. Aristotle had observed that seawater would evaporate and condense into fresh water.
Seawater desalination was mostly utilised on ships and submarines over the next centuries to supply the crew with fresh water during lengthy voyages. Nevertheless, this method was not widely accessible until the industrial revolution and, more specifically, until the creation of desalination facilities.

Suppose you make your living fishing for lobster. You and everyone else are free to set out as many traps as you like. As more and more traps are set up, however, fewer and fewer lobsters are caught. Soon, lobster catches are too small to support your families. A meeting is coming up where you and your fellow lobster fishers will present possible solutions to this problem. What will you propose to combat this tragedy of the commons and restore the fishery?
Explanation and Answer:
This is an opinion based question and there could be many different responses these are just examples of solution to restore the fishery:
-limiting the season during which lobsters can be caught this allows the population to reproduce itself gradually but maintaining it in control
-limiting the amount of lobster that can be caught therefore again letting the population increase

They are Jupiter, Saturn, Uranus and NeptuneThe Gas giants are also called outer planets.Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of _______ and ______. (called Nuclear fusion)
Answer:
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
Explanation:
Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.
Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.
There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.
When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.

1. compare the term " ground state " to the energy of an atom and its electron configuration.
2. describe how metallic bonding accounts for the conductive property of metals. discuss both electrical and heat conduction.
3. describe the relationship between intermolecular forces and physical property. What is the cause of the relationship?
Answer:
1. The ground state describes the lowest possible energy that an atom can have. An electron is normally in its ground state, the lowest energy state available.
2. In a metal, atoms readily lose electrons to form positive ions (cations). These ions are surrounded by delocalized electrons, which are responsible for conductivity. The solid produced is held together by electrostatic interactions between the ions and the electron cloud. These interactions are called metallic bonds. The metallic bonding model explains the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end.
3. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase. The physical state and properties of a particular compound depend in large part on the type of chemical bonding it displays. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound.

Enzymes are catalysts in living things, including in the molds and bacteria that cause the spoiling reactions that decompose food. Use your knowledge of reaction rates to explain why food doesn’t rot as fast when it is covered and refrigerated. For full credit identify two different factors and explain how they are slowing down the reaction.
I already have that the cold temperature will slow down the reaction, and I'm sure the covering has something to do with it, but I'm not sure what the factor could be. I think my answer has to be one of the factors we learned in class (which are catalyst, concentration, surface area, and temperature).

Calculate the number of moles of NaOH that are needed to react with 500.0 g of
H2SO4 according to the following equation:
H2SO4 + 2NaOH →
Na2SO4 + 2H2O
Answer:
2.55 moles of NaOH are needed react with 500.0 gram of H₂SO₄.
Explanation:
Given data:
Mass of H₂SO₄ = 500.0 g
Number of moles of NaOH needed = ?
Solution:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Number of moles of H₂SO₄:
Number of moles = mass/molar mass
Number of moles = 500.0 g/ 98.07 g/mol
Number of moles = 5.09 mol
Now we will compare the moles of H₂SO₄ and NaOH.
H₂SO₄ : NaOH
1 : 2
5.09 : 1/2×5.09 = 2.55 mol
Thus, 2.55 moles of NaOH are needed react with 500.0 gram of H₂SO₄.
The number of mole of NaOH required to react with 500 g of H₂SO₄ is 10.2 moles
We'll begin by calculating the number of mole of in 500 g of H₂SO₄
Mass of H₂SO₄ = 500 gMolar mass of H₂SO₄ = (2×1) + 32 + (16×4) = 98 g/mol Mole of H₂SO₄ =?Mole = mass / molar mass
Mole of H₂SO₄ = 500 / 98
Mole of H₂SO₄ = 5.1 moles
Finally, we shall determine the mole of NaOH required for the reaction.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
From the balanced equation above,
1 mole of H₂SO₄ required 2 moles of NaOH.
Therefore,
5.1 moles of H₂SO₄ will require = 5.1 × 2 = 10.2 moles of NaOH
Thus, 10.2 moles of NaOH is required for the reaction

Benjamin Franklin invented the lightning rod as a way to prevent lightning from causing damage to property or people. Use this same idea to construct a device that can protect a person from static charge buildup in their body as they run on a treadmill. Consider that the person wears rubber-soled shoes that rub on the treadmill's running surface, which generates static charges that build up in their body. When the person finishes her workout, she can receive an unpleasant shock when she steps off the treadmill and touches an object that suddenly discharges all of that charge. How can you apply Ben Franklin's idea of a lightning rod to solve this problem? Create a sketch showing how your shock protection system works. Your sketch should be labeled and clearly indicate how the excess static charge in a human body is discharged by the system you design. 12 f(x) (1000) 1 G
Answer:
By 1750, in addition to wanting to prove that lightning was electricity, Franklin began to think about protecting people, buildings, and other structures from lightning. This grew into his idea for the lightning rod. Franklin described an iron rod about 8 or 10 feet long that was sharpened to a point at the end.
