Answer: 8 oxygen, 16 hydrogen

Explanation:

One oxygen mixed with two hydrogen makes water, which gives us the simple relation of 1:2 multiply by the variable at hand, in this case 8, which gives us 8 oxygen, 16 hydrogen

Answer:

A

Explanation:

mole=mass of the element ÷ atomic mass of the element.

mole=6÷atomic mass of flourine.

The step at A correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine. That is "Divide 6 by the atomic mass of fluorine".

Given that,

The mass of fluorine = 6 grams

The atomic mass of one mole of fluorine = 18.99

So, the number of moles of 6 grams of fluorine= \(\frac{6}{18.99}\)

Therefore, the step is given in option A: "Divide 6 by the atomic mass of fluorine" is the correct step that converts the 6 grams of fluorine to an equivalent number of moles of fluorine.

Answer:

A) 8.51 × 10²⁴  

Explanation:

1. Gather all the information

            2H₂S + SO₂ ⟶ 3S + 2H₂O

n/mol:   9.42

2. Calculate the moles of S atoms

The molar ratio is 3 mol S:2 mol H₂S

\(\text{Moles of S} = \text{9.42 mol H$_{2}$S} \times \dfrac{\text{3 mol S }}{\text{2 mol H$_{2}$S }} = \text{14.13 mol S}\)

3. Calculate the atoms of S

\(\text{Atoms of S } = \text{14.13 mol S} \times \dfrac{6.022 \times 10^{23}\text{ S atoms}}{\text{1 mol S}} = \mathbf{8.51 \times 10^{24}}\textbf{ S atoms}\)

The sulfur atoms that should be generated is \(A) 8.51 \times 10^24\).

Given that,

\(= \frac{3\times 6.022\times 10^23\times 0.42}{2}\\\\= 85.0909 \times 10^23\\\\= 8.509 \times 10^24\\\\= 8.51 \times 10^24\)

Therefore we can conclude that the sulfur atoms that should be generated is \(A) 8.51 \times 10^24\).

Answer:

The answer is often done in nature preserves

Explanation:

The region Y in the diagram represents the action that is  is often done in nature preserves. Hence, option b is correct.

Captive breeding and habitat preservation are two important ways to protect biodiversity. Captive breeding involves the capture and breeding of endangered species in a controlled environment to increase their population size.

This method is used for species that are in danger of extinction in the wild due to factors such as habitat destruction, poaching, and disease. By breeding the species in captivity, the population can be increased and eventually released back into the wild to help restore the species' population.

Habitat preservation, on the other hand, involves protecting natural habitats from human activities such as logging, mining, and urban development.

By preserving habitats, the native species that rely on these habitats can continue to live and thrive, maintaining a healthy ecosystem. This is crucial for the conservation of biodiversity, as many species are dependent on specific habitats for their survival.

Hence, option b is correct.

Explanation:

The erosion of the sand and soil from the shoreline would be a direct result of humans building along the ocean shore zone. When humans build structures along the shoreline. This can lead to increased erosion of the shoreline and loss of the beach.

Building along the ocean shore zone can have several impacts on the natural environment. One of the direct impacts is the erosion of the sand and soil from the shoreline. This occurs because construction can disrupt the natural processes that maintain the beach, such as the movement of sand and the protection provided by vegetation.

For example, building seawalls or other structures can prevent the natural movement of sand and sediment along the beach. This can lead to erosion of the shoreline, as the sand is no longer able to accumulate in areas where it is needed to protect the shoreline. These plants help to hold the sand in place and protect the beach from erosion.

im not sure what exactly you want? if its answering the questions then search up each one and rephrase the answers you get, for instance for mitochondria is the powerhouse of the cell. just write something simple thats what i did when i had to do something like this it took only a couple of minutes

Explanation:

The Organelles help the cell to function efficiently.

I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.

Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.

Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.

Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.

Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.

Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

Explanation:

While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.

Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.

However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
