If a p-wave arrives at 2:10:00 and the s-wave arrives at 2:15:20, how many kilometers from the epicenter is a location?

Answers

Answer:

2.67 x 10⁷km

Explanation:

Given parameters:

    Time of arrival of p-waves  = 2: 10: 00

    Time of arrival of s-waves = 2: 15: 20

Unknown:

Distance of wave from epicenter  = ?

Solution:

 To find the distance of the wave from the epicenter;

     Distance = 3 x 10⁸ x time interval

Time interval = Time of arrival of p-waves  - Time of arrival of s-waves

                       =  2: 10: 00 - 2: 15: 20

                       = 5min 20s

                       = 320s

Now, we need to convert the time to hrs;

        3600s  = 1hr

         320s  = [tex]\frac{320}{3600}[/tex]  = [tex]\frac{4}{45}[/tex]hr

So,

   Distance =  3 x 10⁸  x [tex]\frac{4}{45}[/tex]   = 2.67 x 10⁷km

When exposed to very high temperatures, metals like iron can be turned into fluids that flow and can be poured into molds. What happens within the iron to allow it to flow?

A) The energy of the solid decreases, and the particles begin to collide with high frequency

B)The energy of the solid increases, and the particles begin to slide past each other

C)The solids collide at an increasing rate until reaching equilibrium energy

D)The particles vibrate about equilibrium in an effort to minimize energy

Answers

Answer: B) The energy of the solid increases, and the particles begin to slide past each other.

Explanation:

The energy of the solid matter is required to be increased so that molecules of the solid matter get separated from each other and an transition from solid matter to liquid matter occurs. The liquid components of the matter will slide past each other as they have obtain energy for fluidity. The liquid iron can be molded into any shape and the energy decreases considerably.

A rock mass is 100g. Determine the density of the rock if it has a volume of 20cm3.

Answers

Answer:

The answer is 5.0 g/cm³

Explanation:

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

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

From the question

mass = 100 g

volume = 20 cm³

We have

[tex]density = \frac{100}{20} = \frac{10}{2} \\ [/tex]

We have the final answer as

5.0 g/cm³

How much space does 2 x 10^22 atoms of copper take up?

Answers

Answer:

2.35mL

Explanation:

The amount of space a substance holds is its volume.

Density = mass (g) /volume (L)

Where;

mole = mass/molar mass

Since 1 mol of Cu contains 6.022 × 10^22 atoms.

There are 2 x 10^22/6.022 × 10^22 moles in 2 x 10^22 atoms of copper

2 x 10^22/6.022 × 10^22

2/6.022 × 10^(22-22)

0.332 × 10^0

0.332mol

Mole = mass/molar mass

0.332 = mass/63.5

mass = 63.5 × 0.332

mass = 21.08g

Density = mass/volume

Density of copper (Cu) is 8.96 g/cm³

8.96 = 21.08/v

V = 21.08/8.96

V = 2.35mL or cm³

3.4 moles of CO to liters?

Answers

3.4 moles of CO to liters is 76.2

Answer:

76.2 L of [tex]CO_{2}[/tex]

Explanation:

Converting the unit of moles to liters is very easy if you know the value of a mole to a liter. Remember that 1 mole is equivalent to 22.413962 L.

Step 1:

3.4 mol [tex]CO_{2}[/tex] x 22.413962 [tex]\frac{liters}{mole}[/tex] = ?

Step 2:

Cancel out the moles.

Step 3:

If you multiply 3.4 by 22.413962, the answer is 76.2

Step 4:

Don't forget to put the units every time you answer. So the answer is: 76.2 L of [tex]CO_{2}[/tex]

Answers

Answer:

Oxgen- cannot be separated

Water - chemical change

Gold - cannot be separated

Carbon Dioxide - chemical change

Carbon​ - cannot be separated

Explanation:

A pure substance, which can either be an element or a compound, contains only one type of such element or compound. In opposition to a mixture, pure substances cannot be separated by physical means.

- Elements as a pure substance cannot be separated because it contains only one type of atom. However, compounds contain two or more types of atoms, and hence, can only be separated into its individual atoms via chemical means.

In this question, oxygen (O2), Gold (Au) and carbon (C) are all elements and hence cannot be separated. Carbon dioxide (CO2) and water (H2O) are compounds because they contain two different atoms respectively, hence, can be separated into individual atoms.

What is the last energy level of N? Mg?

Answers

Answer:

2

3

Explanation:

To infer the last energy of the given atoms, we need to write their electronic configuration:

For N = 1S² 2S² 2P³

     Mg  = 1S² 2S² 2P⁶ 3S²  

The energy levels are usually designated as;

   n = 1

   n = 2

   n = 3

   n =4

For N, the last energy level is 2

     Mg, the last energy level is 3

We can also determine this number by the periods the atoms can be found.

How many atoms are in the following formula?
3Al2O3

Answers

Answer:

15 atoms total

Explanation:

2 Al atoms + 3 O atoms = 5 Al2O3 atoms

5 Al2O3 atoms * 3 = 15

another way to do it is:

2 Al atoms * 3 = 6 Al atoms

3 O atoms * 3 = 9 O atoms

6+9 =15 atoms total

The number of atoms in the given 3Al₂O₃ is 15 atoms.

What are atoms?

Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.

These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.

The compound is 3Al₂O₃

This means there are three moles of aluminum, and three moles of oxygen.

2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms

5 Al₂O₃ atoms x 3 = 15

The elaborative way is:

2 Al atoms x 3 = 6 Al atoms

3 O atoms x 3 = 9 O atoms

6 + 9 =15 atoms total

Thus, the number of atoms is 15 atoms.
