The best description of the relationship between population size, carrying capacity, and limiting factors is: "The size of a population usually stays near its carrying capacity due to limiting factors."

Carrying capacity refers to the maximum number of individuals that a particular environment can sustainably support. It represents the limit to which a population can grow given the available resources, such as food, water, and habitat. Limiting factors, on the other hand, are the factors that restrict population growth by reducing birth rates, increasing death rates, or limiting access to resources.As a population approaches its carrying capacity, limiting factors come into play and regulate the population size. These limiting factors can include competition for resources, predation, disease, availability of suitable habitat, and other environmental factors. They act as checks on population growth, preventing it from exceeding the carrying capacity of the ecosystem.

Therefore, the size of a population usually stays near its carrying capacity because the limiting factors ensure that the population does not exceed the available resources and ecological limits of the environment. If the population surpasses the carrying capacity, the limiting factors will intensify, causing a decline in resources and an increase in mortality rates, which ultimately brings the population back towards the carrying capacity.It's important to note that the relationship between population size, carrying capacity, and limiting factors is dynamic and can vary depending on various ecological and environmental factors.

Answer:

the liquid becomes equal to the rate of condensation

Explanation:

ive come across this question before! and i think its right! :D

The vapor pressure of a liquid at a provided temperature is measured when the rate of evaporation of a liquid evolves equally to the rate of condensation.

Evaporation is the procedure by which water transforms from a liquid to a gas or vapor.

Evaporation is the primary route that water moves from the liquid circumstances around into the water cycle as atmospheric water vapor.

When a molecule around the surface absorbs adequate energy to overwhelm the vapor pressure, it will exit and join the surrounding air as a gas.

The given statement, As noted in chapter 14, the exhaust and fly ash from the burning of coal releases many toxic chemicals harmful to life, including humans is True.

Because Externalized costs are costs that are incurred by people other than those directly involved in an activity. In the case of coal burning, the exhaust and fly ash releases many toxic chemicals, such as mercury, that are harmful to life and human health.

Mercury is concentrated in animal tissues, leading to neurological disorders and other health problems. Therefore, the indirect costs associated with the use of coal best represent externalized costs. The indirect costs associated with the use of coal, such as the release of toxic chemicals and the resulting health problems, are examples of externalized costs.

Externalized costs are those that are not directly paid for by the producer or consumer of a product or service, but are instead borne by society as a whole. In the case of coal, the externalized costs include the negative impacts on the environment and public health from the release of harmful substances during the burning of coal. These costs are not reflected in the price of coal, and therefore are not directly paid for by the producer or consumer, but are instead borne by society as a whole.

Answer:

-2, -2 and 0.

- Respiration is a process in which energy is produced and photosynthesis is a process in which energy is used.

Explanation:

Hello,

In this case, oxygen is a substance that is used for animals and us to acquire the energy necessary for several functions by the cellular respiration (we also need glucose), besides, it is a product of the photosynthesis carried out by vegetable cells (plants). Moreover, carbon dioxide and water are used by the plants to produce oxygen we need as well as glucose via the aforementioned photosynthesis, thus, both chemical reactions are shown below:

\(C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O\ \ \ respiration\\\\6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2\ \ \ photosynthesis\)

In such a way, since the oxygen in carbon dioxide and water has an oxidation state of -2 (reduced form) we can say that the respiration is a process in which energy is produced and since the oxygen yielded during the photosynthesis has an oxydation state of 0, we can say that photosynthesis is a process in which energy is used.

Best regards.

Where n is the number of carbon atom

Therefore, the answer is octyne

Example of each of the following mixtures and state whether it is a homogeneous or heterogeneous mixture

A mixture of a solid and a liquid -  Dirt and water [mud] (Heterogenous - mud can settle down at the bottom and leaving the mixture with much less mud at the top of the container than at the bottom)

A mixture of two gases - Smoke and fog [smog] (Heterogenous - Smog often carries around a lot of different particles other than just smoke and fog. These are not the same particles as another smog cloud a few miles over)

A mixture of two liquids - Milk and chocolate syrup [chocolate milk] (Heterogenous - The chocolate syrup can settle at the bottom leaving different amounts on both top and bottom of the mixture.)

A mixture of two solids - Copper and Zinc [brass] (Homogenous - Brass is always copper + zinc, though the ratios can vary greatly. If it were heterogenous we would see variety in things such as color, which we don't)

Mixture is the compound made up of two or more chemical component which are not chemically linked called as mixture

Here mixture of solid and liquid is dirt and water means water is the liquid whereas dirt is the solid and mixture of two gases are smoke and fog this two are gases that's why it is called mixture of gases and mixture of two liquid are milk and chocolate syrup because they are syrup that's why they are mixture of two liquid and mixture of two solid are copper and zinc copper is also the solid and zinc is also the solid that's why it is the mixture of two solid

To solve this we must be knowing each and every concept related to mole.  Therefore, 576g is the mass of oxygen produced from 12.00 moles of  NaCIO\(_3\).

A mole is merely a measuring unit. In reality, it is one of International System of Units' seven foundation units (SI). When basically determines are insufficient, new units are created.

Chemical reactions frequently occur at levels that use grams would be inappropriate, but using actual figures of atoms/molecules/ions would also be misleading.

It's much easier to write' mole' than '6.02x10²³' whenever you wish to refer to a huge number of things. That is essentially why and how this particular component was created.

2NaCIO\(_3\) \(\rightarrow\)2 NaCI+ 3 O\(_2\)

moles of NaCIO\(_3\) =12.00 moles

1 mole of  NaCIO\(_3\) requires 3/2 moles of  O\(_2\)

12.00 moles of  NaCIO\(_3\) requires (3/2)×12.00 moles=18 moles of  O\(_2\)

mass of oxygen=18 moles× 32g/mol

                         =576g

Therefore, 576g is the mass of oxygen produced from 12.00 moles of  NaCIO\(_3\).

Answer:

\(16\ \text{ppm}\)

Explanation:

Mass of one tablet = 20 mg

Mass of two tablets = \(2\times 20=40\ \text{mg}\)

Percent that is soluble in water = 40%

Mass of tablet that is soluble in water = \(0.4\times 40=16\ \text{mg}\)

So, mass of solute is \(16\ \text{mg}\)

Density of water = 1 kg/L

Volume of water = 1 L

So, mass of 1 L of water is \(1\times 1=1\ \text{kg}=1000\ \text{g}\)

PPM is given by

\(\dfrac{\text{Mass of solute}}{\text{Mass of solvent}}\times 10^6=\dfrac{16\times 10^{-3}}{1000}\times 10^6\\ =16\ \text{ppm}\)

Hence, the concentration of iodine in the treated water \(16\ \text{ppm}\).

Explanation:

CO₂ have a higher boiling point than CH₄ when they both possess dispersion forces because CO₂ consists of polar bonds between carbon and oxygen.

Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids.

Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.

Explanation:

It is element number 26 on the periodic table.

Answer:

Iron is an element because it is a pure substance, air is a mixture, salt and sugar are compounds.

C₃H₈ has an empirical formula mass of 44 g/mol. Hence, C₃H₈ is also the molecular formula.

When twο οr mοre distinct elements are chemically mixed in a specific ratiο, the resultant substance is knοwn as a cοmpοund.  Chemical bοnds, such as cοvalent bοnds, iοnic bοnds, οr metallic bοnds, hοld the cοnstituent parts οf a cοmpοund tοgether.

We must first cοmpute the mοles οf each element present in the cοmpοund in οrder tο derive its empirical fοrmula.

We can figure οut hοw many mοles οf carbοn and hydrοgen there are in 100 g οf the chemical by dοing the fοllοwing calculatiοn:

81.71 g / 12.011 g/mol = 6.80 moles of carbon

18.29 g / 1.008 g/mol of hydrogen = 18.15 moles.

The simplest whole number ratio of carbon to hydrogen atoms must next be determined. In order to do this, we divide both values by the lesser amount, in this case 6.80 moles:

Carbon: 6.80 moles / 6.80 moles = 1.00 Hydrogen: 18.15 moles / 6.80 moles = 2.67

To get whole numbers, we must multiply both values by a factor. By multiplying each by 3, the smallest whole number ratio is obtained:

1.00 x 3 = 3 carbon

2.67 x 3 = 8.01 x 8 for hydrogen.

As a result, the compound's empirical formula is C₃H₈.

Knowing the compound's molecular weight is necessary to determine its molecular formula. The compound's MWt (molecular weight) is 44, as stated.

C₃H₈ has an empirical formula mass of 44 g/mol. Hence, C₃H₈ is also the molecular formula.

Any molecule with the empirical formula C₃H₈, like propane, might be the structural formula of the chemical (CH₃CH₂CH₃).
