How many atoms in 8.9 moles of iron

Answer:

Solid and gas

Explanation:

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.

The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.

Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.

Explanation:

you welcome

Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.

It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.

Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.

The whole soil, from the surface to its lowest depths, develops naturally as a result of these five factors. The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time.

Explanation:

Answer:

The process of soil formation depends on the presence of the new soil material obtained by scraping or settling.  These two actions are responsible for using new starting materials to initiate the process of soil formation.

The different components/factors of healthy soil are:

1. Time

2. Parental material

3. Topography and relief

4. Climate

5. Organisms (living things such as animals, humans, plants, and animals)

Answer:

When the two substances are mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. This initial reaction results in two new chemicals: carbonic acid and sodium acetate. A decomposition reaction is the second reaction that occurs.

Both before and after the reaction, the mass is unchanged. Mixing vinegar with baking soda causes a chemical reaction. Carbon dioxide gas is one of the new chemicals that are created.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The intensity of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram is the primary mass unit in the SI.

A majority of an atom's mass is contained in its nucleus. For discussions of how atoms interact with one another and therefore for chemistry, biology, and electronics, the surrounding electrons are of course essential.

The hydrogen ions in the vinegar and sodium and bicarbonate ions in the baking soda interact when the two substances are combined. Carbonic acid and sodium acetate are the two new compounds produced by this first reaction.

Thus, According to the Law of Conservation of Mass, if the carbon dioxide gas is confined, the mass of the components will remain the same.

Answer:

c

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.

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

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.

Answer:

rocks are destroyed

explanation

ricks are never destroyed they descompose

There are no steps in the rock cycle that do not connect directly to one another. The rock cycle describes the continuous process by which rocks are formed, weathered, eroded, transported, deposited, and lithified, leading to the formation of new rocks.

Each step of the rock cycle is interconnected and depends on the other steps. For example, the formation of sedimentary rocks requires the weathering and erosion of preexisting rocks, the transportation and deposition of the resulting sediments, and the lithification of the sediments into rock.

Without the weathering and erosion of preexisting rocks, there would be no sediment to form sedimentary rocks.

Similarly, the formation of metamorphic rocks requires the heat and pressure of burial and tectonic activity, which in turn is influenced by the existing rock formations and geological processes of the area.

Another example is the formation of igneous rocks, which can occur through the melting and solidification of preexisting rocks, or through volcanic activity.

Hey,

So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.
