At which location would an object’s weight be the greatest?

on Pluto
on Earth
on the Sun
on the moon

Answers

Answer 1

Answer:

the sun

Explanation:

because its the center

Answer 2

The object's weight would be the greatest:

C. on the sun, this can be accounted on the Earth's gravity

Object's weight at the sun:

At 12 PM, when the Sun is straightforwardly beneath, it pulls on an item in a similar course as the draw of the Earth; around early afternoon, when the Sun is straight above, it pulls on an article toward a path inverse to the draw of the Earth.

Thus, all articles ought to be heavier around evening time than they are at the day. Sun's gravitational draw on earth-bound objects is around 0.0006 of earth's gravity.

Hence, option c is correct.

lonic bonds tend to form between two atoms with what characteristics?​

Answers

Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

Explanation:

Ionic bonds tend to form between two atoms with a high electronegativity difference.

Explanation:

An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compounds

So, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

C
The particles of matter have zero kinetic energy and potential energy.

D
The particles of matter are arranged in different ways for the different state.

Answers

Answer:

D .The particles of matter are arranged in different ways for the different state.

Explanation:

The kinetic molecular theory is used to explain the forces between molecules and the energy the molecules possesses.

One of the key postulate of this theory is that;

The particles of molecules are continual state of motion. They posses kinetic energy. In gas, the particles are random and moves in a straight line motion. Liquids are less random and only slide past one another. Solids have a restricted space and the molecules are free to move about.

Therefore, we can see that the particles of matter are arranged in different ways for different state.

By the IUPAC Naming Convention followed by every chemical standards, the structure from the question is named as 4,4-dimethyl heptane.

IUPAC Stands for International Union of Pure and Applied Chemistry.This organisation issued some standards for naming any chemical components that is followed world wide.

According to the IUPAC Standards:

First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:

[tex]-CH3[/tex] is termed as methyl

As the both the methyl group( [tex]-CH3[/tex]  ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.

Suppose you found a material in which 12.5% of the original radioactive atoms were present. If the half-life is 10years, how old is the material?

Answers

Answer:

The material is 30 years old.

Explanation:

The decay of radioactive isotopes can be modelled by the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m(t)}{\tau}[/tex] (Eq. 1)

Where:

[tex]m(t)[/tex] - Current mass of the isotope, measured in grams.

[tex]\tau[/tex] - Time constant, measured in years.

[tex]\frac{dm}{dt}[/tex] - Rate of change of the isotope in time, measured in grams per year.

After some handling, we find that the solution of the differential equation is:

[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (Eq. 2)

Where:

[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.

[tex]t[/tex] - Time, measured in years.

Now we clear time within the expression above:

[tex]t = -\tau\cdot \ln \frac{m(t)}{m_{o}}[/tex]

Besides, we determine the time constant in terms of the half-life ([tex]t_{1/2}[/tex]), measured in years:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)

If we know that [tex]t_{1/2} = 10\,yr[/tex] and [tex]\frac{m(t)}{m_{o}} = 0.125[/tex], then the age of the material is:

[tex]\tau = \frac{10\,yr}{\ln 2}[/tex]

[tex]\tau = 14.427\,yr[/tex]

[tex]t = -(14.427\,yr)\cdot \ln 0.125[/tex]

[tex]t \approx 30\,yr[/tex]

The material is 30 years old.

The melting point of Paradichlorobenzene is 53.0C .In a laboratory activity two students try to verify this value .The first student records 51.5C,53.5C ,55.0C,52.3C and 54.2C.The second student records 52.3C,53.2C,54.0C AND 53.5C. A. Calculate the average value for the two students. B. Calculate the Percent error for each student. C. Which student is most precise ?Most accurate? Explain.

Answers

Answer:

a. 53.3°C.

b.  Percent error for both students is 53.3°C

c. Both students are equal in accuracy.

2nd student is most precise

Explanation:

The percent error is defined as:

|M - T| / T * 100

Where M is measurement,

and T is theoretical value

a. To obtain the average of both measurements we need to sum the measurements and divide these in the number of measurements:

51.5°C+53.5°C+55.0°C+52.3°C+54.2°C+52.3°C+53.2°C+54.0°C+53.5°C / 9

= 53.3°C

b. Percent error for 1st student:

51.5°C+53.5°C+55.0°C+52.3°C+54.2°C / 5 = 53.3°C

|53.3°C - 53.0°C| / 53°C * 100

0.57%

Percent error for 2nd student:

52.3°C+53.2°C+54.0°C+53.5°C / 4 = 53.3°C

|53.3°C - 53.0°C| / 53°C * 100

0.57%

c. Now, precision is how close are the measurements to each other and the accuracy how close are the measurements to the theoretical value:

The accuracy is obtained with percent error, the lower percent error the most accurate measurement. That means:

both students are equal in accuracy.

And precision is obtained with relative standard desviation.

Desviation standard / Average * 100

(We can solve the standard desviation in a scientific calculator):

1st student:

2.65%

2nd student:

1.34%

The lower RSD the most precise measurements.

2nd student is most precise

Eric is investigating what happens when heat is added or removed from an object. First he places a mug of hot chocolate in this hand and records the temperature of the hot chocolate and the surface of his hand every five minutes for a total of 15 minutes. He repeats this procedure when investigating heat flow with an ice cube. Use the diagram to answer the question below. A flowchart illustration with two forward (right direction) arrows and two backward (left direction) arrows. The phrase Mug of chocolate is followed by the forward arrow A that leads to the word Hand. The word Hand is followed by the forward arrow C that leads to the phrase Ice cube. The word Ice cube is preceded by the backward arrow D that leads to the word Hand. The word Hand is preceded by a backward arrow B that leads to the phrase Mug of hot chocolate. What could Eric conclude about what happens when heat is added or removed from an object after he completed his test with the mug of hot chocolate? A. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was absorbed by his hand. B. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was released from his hand. C. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by the mug. D. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by his hand.

Answers

Answer:

A). Arrow A shows the direction heat flowed because the temp of his hand increased as the heat was absorbed by his hand.

Explanation:

As per the given description, Eric can conclude that when 'heat is either prepended or separated from an object after the completion of his test' as arrow A displays the direction in which the heat has flown because his hands' temperature increased after the heat was absorbed by his hand. It implies that heat is prepended when the temperature of his hand increases and vice versa when the heat is removed. Thus, option A is the correct answer.

letter A is right.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.
