Scientists say that photosynthesis and cellular respiration create a cycle that is essential to almost all life on Earth. Use your knowledge of these processes to explain how an oil spill that kills a large percentage of the photosynthetic organisms living in the ocean could affect humans.​

Answers

Answer:

Explanation:

An oil spill is a catastrophic event in the environment. It can negatively affect both plants and wildlife while causing human suffering and economic losses. An oil spill needn't be on the scale of the Exxon Valdez or Deepwater Horizon disasters. The U.S. Environmental Protection Agency (EPA) estimates that 200 million gallons of used oil are disposed of improperly each year.

Spilled oil floats on the surface of the water, blocking the sunlight, from reaching the plants within the body of water. Spilled oil may also directly coat the leaves of plants -- where most of the work of photosynthesis occurs -- reducing or blocking out sunlight. Without sunlight, plants lack the energy needed to undergo photosynthesis.

An oil spill can impact photosynthesis by reducing water quality. Not only does the presence of oil directly poison the water, but the spill can kill sea life, birdlife and other wildlife that uses an aquatic habitat. A large die-off can increase bacteria levels and lower the pH of a body of water. The reduction in water quality can stress plants, essentially halting photosynthesis.

How many moles of H 2 will I need to make 5 moles of NH3?
12 SSO

Answers

Answer:

7.5 moles of hydrogen is required

Explanation:

Given data:

Number of moles of H₂ needed = ?

Number of moles of NH₃ = 5 mol

Solution:

Chemical equation:

N₂ + 3H₂     →     2NH₃

Now we will compare the moles of ammonia and hydrogen.

         NH₃       :         H₂  

          2           :          3

          5           :         3/2×5 = 7.5 mol

Thus, 7.5 moles of hydrogen is required.

Make an equation

K, left = 2, right = c⇒c=2

C, left = 1, right = b⇒b=1

Ba, left = a, right = b⇒a=b⇒a=1

The equation becomes :

three bonds with hydrogen to

atoms do you think will bond
with an atom of phosphorous?

Answers

Answer:

Three

Explanation:

Nitrogen and phosphorus are on the same group in the periodic table. Elements in the same group have similar chemical properties. This is because of the number of valence electrons that they share among each other.

 The valence electrons are the outermost shell electrons found within an atom.

Nitrogen and phosphorus can both be found on the fifth group on the periodic table.

Their oxidation state is:

either 5 or 8-5  = 3

Since phosphorus bonds with 3 hydrogen atoms, nitrogen will also do the same.

What is the formula unit of barium fluoride?

Answers

Answer: [tex]BaF_{2}[/tex]

Explanation: Because barium is in Group 2, it forms ions with a charge of +2. Fluorine, in Group 17, form ions with a charge of -1. Cross the charges to get the subscripts (Since Ba has a charge of +2, F has a subscript of 2. Because F has a charge of -1, Ba needs a subscript of 1). Therefore, a formula unit of the compound is [tex]BaF_{2}[/tex].

If an object is moving right at 10 N and a force is applied from the left at 8N, what is the net force on the object?

Answers

Answer:

If an object is moving at a constant speed in a constant rightward direction, then the acceleration is zero and the net force must be zero.

According to Aristotle, a force is anything that causes an item to move "unnaturally." One of the first scientists to explore force and gravity was Sir Isaac Newton. A push or a pull is all that constitutes a force. It might be compared to pushing or pulling on an object.

What is force?

An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force.The definition of force in physics is. The push or pull on a mass-containing item changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

The net force is:

Fnet = Fr - Fl = 10 - 8 = 2N

From the following elements: lithium, beryllium, and fluorine, predict which
one will have the largest second ionisation energy. Explain your answer.

Answers

Answer:

The element that has the largest second ionization energy is;

Lithium, Li

Explanation:

The given elements and their positions on the periodic table are;

1) Lithium is located in group 1, period 2 position on the periodic table

2) Beryllium is located in group 2, period 2 position on the periodic table

3) Fluorine is located in group 17, and period 2 position on the periodic table

The first ionization energy of the atoms in the periodic table increases across the periods from left to right and also increases from bottom to the top within a group

However  for the second ionization energy, which is the energy required to remove an electron from an atom that has one less electron, we have;

The electron configuration of the given of ions that take part in the reaction for the removal of the second ionization energy are;

Li⁺ = [He} 2s⁺

Therefore, the second ionization energy is the removal of an electron from the stable duplet of the helium atom (the core of the lithium atom) which require about 7297 kJ/mol

For beryllium, we have;

Be⁺ = [He]2S¹⁺

Therefore, the second ionization requires the removal of the remaining one electron in the valence shell, which will then lead to the remaining structure of the stable helium core and therefore, the second ionization energy of beryllium is about 1757 kJ/mol, which is low compared to helium

For fluorine, we have;

F⁺ = [He] 2s² 2p⁴⁺

Therefore, the second ionization of fluorine remains high due to the increased attraction of the positively charged fluorine ion for electrons than electrically neutral fluorine atom that has equal number of protons and electrons such that the second ionization energy of fluorine is higher than the first ionization energy and is about 3357 kJ/mol

Therefore, the element that has the largest second ionization energy is lithium, Li.

Look at the properties of Oxygen and Silicon - the two most abundant elements in the Earth's crust - by clicking on their symbols on the Periodic Table.

Explanation:

Answer:

D. silicon and oxygen

Explanation:

The most abundant elements on the earth's crust are silicon and oxygen. Silicon and oxygen forms a wide range of silicate minerals they are found in the crust.

There are many silicates which are derived from the basal units of silicon and oxygen combining together. Other atoms or elements then combines with the silicate framework.

Oxygen is about 46% abundant in the crust whereas silicon takes about 28% to be the second most abundant element on the crust.

Silicate minerals abounds in rocks and within the soil.
