information, calculate the density of lead.

Answers

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{698}{50.5} \\ = 13.8217...[/tex]

We have the final answer as

A decrease in thermal energy
Hide hint for Question 9

Answers

answer: increase in thermal heat

explanation: In order to change the state, more energy is needed.
When you want to go from a lower state (solid) to a higher state (liquid) then you need more energy. and more energy means more heat in this case. if it was going from liquid to solid, you would need less thermal energy.

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calculate the density of the solid.

Answers

Answer:

The answer is 8.40 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 56.4 - 50 = 6.4 mL

We have

[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]

We have the final answer as

8.40 g/mL

Ca, F, Ne, Fe?

Answers

Answer:

The electronegativity from order of least to highest is:

Ne, Ca, Fe, F

Explanation:

Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).

According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.

Hence, based on Pauling scale, the order of electronegativity from least to highest is:

Ne > Ca > Fe > F

at 25°C
. Which of the following graphs shows the distribution of speeds for a sample of O2(g)
at 25°C
(dashed line) ?

Answers

Answer:

A

Explanation:

The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.

Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.

Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.

For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

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.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Does Soda show acidic properties?

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

B

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.

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.
