The properties of a natural resource that make it useful for humans as a material or energy source is the ability to convert mass into energy and vice versa.

The expression natural resources make reference to all types of matter and energy extracted from nature that can be used to produce goods and services.

Some examples of natural resources include for example irreversible resources such as fossil fuels (i.e., oil, or coal, gas, minerals such as metals, rocks, etc) as well as those based on the use of reversible energy such as eolic air energy, solar radiation or sunlight, soil and hydric resources or water.

Therefore, with this data, we can see that natural resources can be defined as any material and or energy obtained from nature that may be irreversible or reversibly used to produce goods and services.

Explanation:

Sodium has an atomic number of 11, thus, the neutral atom has 11 electrons. The electron configuration is:

Na: 1s² 2s² 2p⁶ 3s¹

To gain stability, it loses an electron from its outer shell to form the cation Na⁺. Its electron configuration is:

Na⁺: 1s² 2s² 2p⁶

If it were to lose a second electron to form a Na²⁺ cation, the electron should be lost from the 2p orbital subshell and its electron configuration would be:

Na²⁺: 1s² 2s² 2p⁵

Draw a structural formula for the major product of the reaction shown:

The structural formula for the major product (2-butene) of the given reaction is as follows:$$\ce{CH3CH2CH=CH2}$$

The given reaction is an acid-catalyzed dehydration reaction.

During the reaction, the hydroxyl group (OH) and the adjacent hydrogen atoms (H) on the reactant alcohol (2-butanol) undergo dehydration (loss of water) to form an alkene (2-butene) as the major product.

The reaction is shown below:$$\ce{CH3CH2CH2CH2OH + H2SO4 ->[\Delta] CH3CH2CH=CH2 + H2O}$$To draw the structural formula for the major product of the given reaction, we need to consider the following points:

1. The reactant alcohol (2-butanol) is a four-carbon alcohol with the hydroxyl group (OH) attached to the second carbon atom (C2) of the chain.

2. The product alkene (2-butene) will be a four-carbon alkene with a double bond between the second and third carbon atoms (C2 and C3) of the chain.

The other two carbon atoms will have a single bond with the adjacent carbon atoms and a hydrogen atom each attached to them.

3. The major product will be formed via the elimination of water (dehydration) between the hydroxyl group (OH) and the adjacent hydrogen atoms (H) on the second carbon atom (C2) of the reactant alcohol (2-butanol).

4. The acid catalyst (H2SO4) does not participate in the reaction and remains unchanged. It only facilitates the formation of the alkene by providing a proton (H+) to the hydroxyl group (OH) and a medium for the elimination of water.

Taking into account the definition of density, the mass of ice is 198,773.6004 kg.

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

0.917 g/cm³= mass÷ 2.1677×10⁸ cm³

Solving:

mass= 0.917 g/cm³ ×2.1677×10⁸ cm³

mass= 198,773,600.4 g= 198,773.6004 kg

In summary, the mass of ice is 198,773.6004 kg.

Approximately 0.157 liters or 157 milliliters of the 4.50 M HCl solution can be made by mixing the given solutions.

To determine the volume of 4.50 M HCl that can be made by mixing the given solutions, we can use the concept of the concentration-volume relationship:

C1V1 = C2V2

Where:

C1 = concentration of the first solution

V1 = volume of the first solution

C2 = concentration of the second solution

V2 = volume of the second solution

Let's assign the variables as follows:

C1 = 5.65 M

V1 = unknown volume (we'll solve for this)

C2 = 3.55 M

V2 = 250.0 mL = 0.250 L (since the volume is given in milliliters)

Now we can plug in the values into the equation and solve for V1:

(5.65 M)(V1) = (3.55 M)(0.250 L)

Dividing both sides of the equation by 5.65 M:

V1 = (3.55 M)(0.250 L) / 5.65 M

V1 ≈ 0.157 L

An error during DNA replication would create a gene mutation.

During DNA replication, the genetic information in a cell is copied to make new DNA molecules. However, mistakes can occur during this process, leading to changes in the DNA sequence, which can result in a mutation. Mutations can also be caused by exposure to environmental factors, such as radiation or chemicals, which can damage the DNA molecule directly or affect the cellular processes involved in DNA replication.

Mutations can have a variety of effects on the organism, ranging from no effect to causing serious health problems or even death. Gene mutations can also be inherited from a parent, which can result in genetic disorders or predisposition to certain diseases. Therefore, it is important to understand the mechanisms of gene mutations and their potential impacts on organisms.

B) is the answer in terms of an economic factor that contributes to the stability of a society.

Among the options, option B low tax and interest rates is an economic factor that contributes to the stability of a society.

Tax is a mandatory financial charges imposed on a working person or an owner of a service or property by a governmental organization  for the fund for public expenditure.

The only feasible way to get money to pay for government expenditure on the products and services that the majority of us need is through taxes. But, establishing an effective and fair tax system is far from easy, especially for developing nations that seek to integrate into the global economy.

When trying to set up effective tax systems, developing nations encounter enormous obstacles. First off, most people in these nations work in agriculture or small, unofficial businesses. Their incomes fluctuate since they are rarely paid a regular, fixed wage, and many of them are compensated in cash "off the books."

Therefore, tax which is moderate to be payable by people in all sectors and lo interest rate contribute to the stability of society.

Answer:

Currents in the aluminum sheet set up a magnetic field that opposes the oscillations

Explanation:

It has been stated in the question that the aluminum sheet hangs from one of the arms and passes between the poles of the magnet and causes the magnetic field to decay rapidly. In the absence of this magnetic breaking, the oscillation may continue for a long time.

As the aluminum hangs from one of the sheets and passes between the poles of the magnet, the magnetic flux linked to the sheet changes and emf is induced in the sheet according to Lenz law. As a result of this induced emf, eddy currents are developed on the plate. The Eddy currents opposes the magnetic force on the aluminum sheets. This opposes the oscillation of the aluminum sheet and causes it to come to rest.

The formulas for the compounds formed between platinum ions and bromide ions are Platinum (II) bromide (PtBr2) and Platinum (IV) bromide (PtBr4)

In both of these compounds, the bonding between the platinum ion and the bromide ions is primarily ionic in nature.

In platinum (II) bromide (PtBr2), each platinum ion is surrounded by two bromide ions, and each bromide ion is bonded to one platinum ion. The platinum ion has a +2 charge, and the two bromide ions have a -1 charge each, so the overall charge of the compound is neutral.

In platinum (IV) bromide (PtBr4), each platinum ion is surrounded by four bromide ions, and each bromide ion is bonded to one platinum ion. The platinum ion has a +4 charge, and the four bromide ions have a -1 charge each, so the overall charge of the compound is neutral.

The bond between the platinum ion and the bromide ions is a result of the attraction between their opposite charges.
