Answer:

True

Explanation:

Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness.

Answer:

Pretty sure it's true.

On Earth, we only see part of the moon that is illuminated or not, since it revolves around the Earth. However, the sun is stationary and doesn't move, meaning that one side of the moon is always lit by the sun as it revolves around the Earth.

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?


Apparent magnitude does not use the star's color or temperature.


Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.


Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.


Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

Answer: Answer:

Explanation:

Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.

Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth. Therefore, the correct option is option D.

What is star?

Any large, gaseous celestial body that is capable of producing its own light and illuminates through radiation. Only a very small portion of the tens of milliards of milliards of stars that make up the observable cosmos are readily visible to the eye.

how many carbon dioxide molecules are produced if 8.45 x 1023 of water molecules of water are produced

Answers

The given question is incomplete. The complete question is:

Determine how many carbon dioxide molecules are produced if molecules of water are produced

[tex]C_2H_6(g)+O_2 (g)\rightarrow CO2(g)+H_2O(g)[/tex]

Answer: [tex]5.60\times 10^{23}[/tex] molecules of carbon dioxide are produced

Explanation:

The balanced chemical equation is:

[tex]2C_2H_6(g)+7O_2 (g)\rightarrow 4CO2(g)+6H_2O(g)[/tex]

[tex]\text{Moles of water}=\frac{\text{given molecules}}{\text{Avogadros number}}=\frac{8.45\times 10^{23}}{6.023\\times 10^{23}}=1.40moles[/tex]

Accoding to stoichiometry:

6 moles of water are produced along with = 4 moles of carbon dioxide

Thus 1.40 moles of water are produced along with = [tex]\frac{4}{6}\times 1.40=0.93[/tex] moles of carbon dioxide

Molecules of carbon dioxide = [tex]moles\times {\text {Avogadros number}}=0.93\times 6.023\times 10^{23}=5.60\times 10^{23}[/tex]

1. The pressure of a gas is 100.0 kPa and its volume is 500.0 ml. If the volume increases to 1,000.0 ml, what is the new pressure of the gas?



2. If a gas at 25.0 °C occupies 3.60 liters at a pressure of 10 kPa, what will be its volume at a pressure of 25 kPa?



3. When the pressure on a gas increases three times, by how much will the volume increase or decrease?


4. Boyle's Law deals what quantities?

Answers

Answer:

1) The new pressure of the gas is 500 kilopascals.

2) The final volume is 1.44 liters.

3) Volume will decrease by approximately 67 %.

4) The Boyle's Laws deals with pressures and volumes.

Explanation:

1) From the Equation of State for Ideal Gases we construct the following relationship:

[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)

Where:

[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.

[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.

If we know that [tex]P_{1} = 100\,kPa[/tex], [tex]V_{1} = 500\,mL[/tex] and [tex]V_{2} = 1000\,mL[/tex], then the new pressure of the gas is:

[tex]P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}} \right)[/tex]

[tex]P_{2} = 500\,kPa[/tex]

The new pressure of the gas is 500 kilopascals.

2) Let suppose that gas experiments an isothermal process. From the Equation of State for Ideal Gases we construct the following relationship:

[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)

Where:

[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.

[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.

If we know that [tex]V_{1} = 3.60\,L[/tex], [tex]P_{1} = 10\,kPa[/tex] and [tex]P_{2} = 25\,kPa[/tex] then the new volume of the gas is:

[tex]V_{2} = V_{1}\cdot \left(\frac{P_{1}}{P_{2}} \right)[/tex]

[tex]V_{2} = 1.44\,L[/tex]

The final volume is 1.44 liters.

3) From the Equation of State for Ideal Gases we construct the following relationship:

[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)

Where:

[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.

[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.

If we know that [tex]\frac{P_{2}}{P_{1}} = 3[/tex], then the volume ratio is:

[tex]\frac{V_{1}}{V_{2}} = 3[/tex]

[tex]\frac{V_{2}}{V_{1}} = \frac{1}{3}[/tex]

Volume will decrease by approximately 67 %.

4) The Boyle's Laws deals with pressures and volumes.

Project: Modeling potential and kinetic energy
Assignment Summary
For this assignment, you will develop a model that shows a roller coaster cart in four different positions on a track. You will then use this model to discuss the changes in potential and kinetic energy of the cart as it moves along the track.
Background Information
The two most common forms of energy are potential energy and kinetic energy. Potential energy is the stored energy an object has due to its position. Kinetic energy is the energy an object has due to its motion. An object’s kinetic energy changes with its motion, while its potential energy changes with its position, but the total energy stays the same. If potential energy increases, then kinetic energy decreases. If potential energy decreases, then kinetic energy increases.
Potential energy related to the height of an object is called gravitational potential energy. Gravitational potential energy is directly related to an object’s mass, the acceleration due to gravity, and an object’s height.

c) Later, you will submit this document through the virtual classroom.
Step 4: Evaluate your project using this checklist.
If you can check each criterion below, you are ready to submit your project.

How many grams are there in 9.03 x 1023 molecules of CO2?

Answers

Answer:

The correct answer is - 66g.

Explanation:

Given:

molecules of CO2 = 9.03 x 10^23

We know:

1 mole of any substance = 6.02x10^23 molecules. (Avogadro's number)

M (CO2) = 12 + (2x16) = 12 + 32 = 44g

Solution:

The mass of CO2 with 9.03x10^23 molecules would be:

44g of CO2 = 6.02x10^23 molecules.

So, the mass in grams of CO2 (X) = 9.03x10^23 molecules

Xg of CO2 = (44x9.03x10^23)/6.02x10^23 = 66g

Thus, the correct answer would be - 66gm.

Explanation:

So basically Molar mass is the atomic mass of an element and the atomic mass of Helium is 4.0026 or 4.003 g/mol

8.006 g/mol

multiply the molar mass of helium (4.003) by the subscript and you have your answer!

What mass of iron is formed when 240 g of iron(III) oxide reacts completely with carbon monoxide?

Answers

Answer:

168 g

Reaction:

[tex]Fe_{2}O_{3} + 3 CO >>> 2 Fe + 3CO_{2}[/tex]

Explanation:

First we need to figure out what is the formula mass (Mr) of Fe2O3 (Iron(III) oxide).

The atomic mass of Fe=56, O=16

Mr= 56+56+16+16+16=160 g/mol

We can now figure out the moles of the iron:

240/160 = 1.5 mol

Then we need to find the ratio to make Fe.

In the reaction, we know that 1 mole of Fe2O3 can make 2 moles of Fe. So 1.5 moles of Fe2O3 can make 3 moles of Fe.

And then we need to find the mass of the Fe.

3×56=168 g.

Hence 168g of the iron is made after the reaction.

Answer:

CH5N2

Explanation:.

Mass of C = 44.0g/44.0 g/mol = 1 mol * 1 = 1 mole of C

Mass of H = 45.0 g/18 g/mol = 2.5 moles * 2  = 5 moles of H

Mass of N = 92.0 g/46 g/mol = 2 moles * 1 = 2  moles of N
