\(C6H_14\)is the molecular formula for Hexane, a hydrocarbon. The correct model for \(C6H_14\) is D. Option D is correct answer.

/\/\/\/:Hexane (\(C6H_14\)) is an alkane with a chain of six carbon atoms, having 14 hydrogen atoms. The bond angles of carbon atoms in hexane are 109.5 degrees, and carbon atoms in hexane have a tetrahedral geometry. The representation of a molecule in a model helps to visualize the 3D structure of the molecule. A simple way to represent the 3D structure of hexane is by using the wedge-and-dash notation. In this notation, solid wedges represent bonds coming out of the plane of the paper towards us, and dashed lines represent bonds going back into the plane of the paper away from us.

The temperature of a piece of copper with a mass of 95.4g increases from 25 degrees Celsius to 48.0 degrees Celsius when the metal absorbs 849 J of heat. What is the specific heat capacity of copper?

Answers

Answer:

The answer is 3.87 J/g°C

Explanation:

Here is the equation we are going to use:

\(C=\frac{q}{mT}\)

C= specfic heat in J/g°C

q = heat in joules (J)

m = mass in grams (g)

T = change in temperature

Here is what is given:

q = 849 J

m = 95.4 g

T = 48.0 - 25.0 = 23°C

Find:

Specific heat capacity in J/g

The first thing we are going to do is plug everything into the equation:

\(C = \frac{849J}{(9.54g)(23degreesC)}\)

Then we are going to solve for C

\(C = \frac{849J}{219.42gC} = 3.87 J/gCelsius\)

Hope this helps!

how many protons electrons and neutrons are present in the following atoms​

how many protons electrons and neutrons are present in the following atoms

Answers

Answer:the element is potassium

the proton and electron is 19 and the nuetron is 19

Explanation:

Answer:

The atomic number gives the number of protons 19

p = 19

The atomic mass is the sum of the protons and neutrons

p+n = 39 p = 19

Put p into the equation and solve for n the neutrons

19+n = 39

Subtract 19 from both sides

19-19+n = 39-19

n = 20

The number of electons equal the number of protons in a neutral atom. The positive charge equal to the negative charge. The negative charge is the number of electons. This ion has a charge of +1. So solve for the negative charge.

-19+1 = -18

The negative charge is -18 so

Answers

It’s A) (0.1978)(10.01) + (0.8022)(11.01)

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore option A is correct option.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Mathematically,

average atomic mass=  ∑(relative abundance x mass of isotope)

average atomic mass boron= (relative abundance boron-10  x mass of isotope boron-10)+(relative abundance boron-11  x mass of isotope boron-11 )

average atomic mass boron=(0.1978)(10.01) + (0.8022)(11.01)

A cell is placed into a solution of pure water. what is the tonicity of the water solution?

Answers

A cell is placed into a solution of pure water. The tonicity of the water solution is described as isotonic because the solute concentration of the solution is the same as the solute concentration inside the cell.

A solution that has the same osmolarity, or solute concentration, as another solution is said to be isotonic. Water will flow equally into and out of either solution if a semipermeable membrane is used to separate the two. We can say that the net flow is the same because the flow in and out is equal. So, The tonicity of the water solution is described as isotonic because the solute concentration of the solution is the same as the solute concentration inside the cell. This means that there is no osmotic gradient between the inside and outside of the cell, so there is no net movement of water across the cell membrane.
To explain further, tonicity is a measure of how much solute (e.g. salt or sugar) is present in a solution compared to the solute concentration of a cell. A solution is isotonic when the solute concentration of the solution is the same as the solute concentration inside the cell, so there is no net movement of water across the cell membrane. An isotonic solution is also known as a “balanced” solution.
When a cell is placed into a solution of pure water, the solute concentration of the water is 0, so it is isotonic. The solute concentration of the cell is also 0, so there is no net movement of water across the cell membrane.
In summary, a solution of pure water is isotonic to a cell because the solute concentration of the water is 0 and the solute concentration of the cell is also 0, so there is no osmotic gradient between the inside and outside of the cell.

Answers

As an atom's size shrinks, its electronegativity rises. This is due to the fact that electronegativity and atomic size are inversely related. Because of this, the atomic size decreases as electronegativity rises.

The contact between the nucleus and the surrounding electrons is reduced as the atomic radius rises, which results in a decline in electronegativity.

When comparing HNO3 and HNO2, HNO3 is a stronger acid because it has more electronegative atoms (in this case, more oxygen atoms).
When comparing HCIO and HCIO2, HCIO2 is a stronger acid because it has more electronegative atoms (in this case, more oxygen atoms).
When comparing HCIO and HBrO, HCIO is a stronger acid because it has fewer electronegative atoms (in this case, fewer oxygen atoms).
When comparing CCI3COOH and CBr2COOH, CCI3COOH is a stronger acid because it has more electronegative atoms (in this case, more chlorine atoms).

Answer:

The correct option is;

C. The volume and mass do not change

Explanation:

We note that a piece of paper usually does not compress when load is applied on it.

The mass of the paper does not change as in the process of the paper being crumbled, the matter and therefore, the mass remains constant.

Explain the concept law of diminishing marginal rate of substitution. What is/are the reason/s why the law of diminishing marginal rate of substitution suggest/s that isoquant must be bent toward the origin?

Answers

The law of diminishing marginal rate of substitution indicates that the rate at which one input can be substituted for another decreases as the quantity of one input increases, leading to isoquants being bent toward the origin.


In other words, as the quantity of one good increases, the individual is willing to sacrifice fewer units of the other good to obtain an additional unit of the first good. This reflects a diminishing rate of substitution between the two goods.

The reason why the law of diminishing marginal rate of substitution suggests that isoquants must be bent toward the origin is rooted in the concept of diminishing marginal utility. As more units of a particular input (e.g., labor or capital) are added while holding other inputs constant, the additional output gained from each additional unit of the input will decrease. This diminishing marginal productivity leads to a decreasing MRS.

When isoquants (which represent different combinations of inputs that produce the same level of output) are bent toward the origin, it reflects the fact that as more of one input is used, the amount of the other input that needs to be substituted decreases. This bending signifies the diminishing MRS and captures the idea that a larger quantity of one input can be substituted for a smaller quantity of the other input to maintain the same level of output.

Overall, the law of diminishing marginal rate of substitution indicates that the rate at which one input can be substituted for another decreases as the quantity of one input increases, leading to isoquants being bent toward the origin.
