summerize in your own words Continental crust is much thicker than oceanic crust (averages between 20 to 25 miles thick), but is actually slightly less dense than oceanic crust. The main type of rock on continents is called granite. So if these two types of crust were to collide into each other, what do you think would happen to the oceanic crust? As a whole, notice that the crust is lighter than the mantle. It is sometimes said that the crust "floats" on the mantle like an iceberg in water and that is not too far from the truth and is called isostacy. Finally, the crust is the coldest, most rigid, and brittle layer with lots of folds and fractures.Recall that oceanic crust is denser than continental rock like granite. Thus when two tectonic plates collide, the denser oceanic crust will subduct underneath the lighter continental crust. If the subducting rock becomes stuck, vast amounts of energy builds up. But once the pressure and energy is too great, the rock will rupture creating powerful earthquakes. As the subducted material sinks further, it will begin to melt under great heat and pressure, becoming less dense as it melts, and rise up as magma to form dangerous composite volcanoes. Mountain ranges created by oceanic-to-continental convergence are the Andes mountains in South America, the Cascades in the western United States, and the Ring of Fire in the Pacific Ocean.

What is the mass of substance that exactly fills a 247.2 mL container? The density of the substance is 0.81 g/mL. Give the answer with two decimals.

Answers

Answer:

mass = 200.23 g

Explanation:

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

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

Since we are finding the mass

mass = Density × volume

From the question

Density = 0.81 g/mL

volume = 247.2 mL

Substitute the values into the above formula and solve for the mass

mass = 0.81 × 247.2

= 200.232

We have the final answer as

mass = 200.23 g to 2 decimal places

Why are the trends and exceptions to the trends in ionization energy observed? Check all that apply. -Ionization energy tends to increase down a group because the electrons get farther away from the nucleus. -Ionization energy tends to increase across a period because the nuclear charge increases. -Ionization energy tends to increase across a period because electrons are added to the same main energy level. -The ionization energies of the elements in Group 16 tend to be slightly smaller than the elements in Group 15 because the fourth electron is added to an unfilled p orbital. -The ionization energies of elements in Group 13 tend to be lower than the elements in Group 2 because the full s orbital shields the electron in the p orbital from the nucleus.

Answers

Answer:

2, 3, 5

Explanation:

just the person above

The correct answer is the Ionization energy tends to increase across a period because electrons are added to the same main energy level and the ionization energies of elements in Group 13 tend to be lower than the elements in Group 2 because the full S orbital shields the electron in the p orbital from the nucleus.

What is causing the ionization energy trend?The first ionization energy increases as you move left to right across a period on the periodic table. This is because when the nuclear charge rises, the outermost electron has become more tightly connected to the nucleus.

Answers

Answer:

Option C. 6 protons, 8 neutrons and 6 electrons.

Explanation:

14C has the following:

Mass number = 14

Atomic number = 6

Next we shall determine the number of protons in 14C. This can be obtained as follow:

Atomic number is simply the number protons in an atom. Thus,

Proton = Atomic number

Atomic number = 6

Proton = Atomic number = 6

Proton = 6

Next, we shall determine the number of neutrons in 14C. This can be obtained as follow:

Mass number = proton + neutron

Mass number = 14

Proton = 6

Neutron =.?

Mass number = proton + neutron

14 = 6 + neutron

Collect like terms

Neutron = 14 - 6

Neutron = 8

Finally, we shall determine the number of electrons in 14C.

This can be obtained as follow:

Since the isotope i.e 14C has no charge, it means that the atom is in it's ground state. Hence, the number of protons and the number of electrons are the same i.e

Electron = proton

Proton = 6

Electron = proton = 6

Electron = 6

From the above calculations, 14C has

6 protons, 8 neutrons and 6 electrons.

A 1.0 m solution of a compound with 2 ionizable groups (pka's = 6.2 and 9.5; 100 ml total) has a ph of 6.8. what are the concentrations of the relevant acid and conjugate base?

Answers

Answer:

[H₂A] = 0.2M

[HA⁻] = 0.8M

Explanation:

A compound with 2 ionizable groups has as equilbriums:

H₂A ⇄ HA⁻ + H⁺ ⇄ A²⁻ + H⁺

A pH of 6.8 is near to the first equilibrium:

H₂A ⇄ HA⁻ + H pKa = 6.2

To determine concentrations of the acid H₂A and conjugate base HA⁻ we use H-H equation:

pH = pKA + log [HA⁻] / [H₂A]

6.8 = 6.2 + log [HA⁻] / [H₂A]

0.6 = log [HA⁻] / [H₂A]

3.981 = [HA⁻] / [H₂A] (1)

As concentration of the buffer is 1.0M:

1M = [HA⁻] + [H₂A] (2)

Replacing (2) in (1):

3.981 = 1- [H₂A] / [H₂A]

3.981[H₂A] = 1 - [H₂A]

4.981 [H₂A] = 1

[H₂A] = 0.2M

And [HA] = 1M - 0.2M = 0.8M

4.One rubber tire can generate about250,000 BTUS (1BTU=.0003KW ) when it is burned. The average American home consumes about 10,000 kWh of electricity per year. How many tires would be needed to meet the annual electricity demand of ten homes for one year if the production of electricity from tires is 50% efficient??

Answers

Answer:

The number of tires required to power ten homes for one year is approximately 2,730 tires

Explanation:

The given information are;

The energy generated by burning one rubber tire = 250,000 BTUs

1 BTU = 0.0003 kW

The amount of energy consumed by the average American home = 10,000 kWh

Therefore, the amount of energy generated by burning one tire in kW can be found as follows;

The energy generated by burning one rubber tire = 250,000 BTUs

1 BTU = 0.0003 kW

∴ 1 BTU × 250,000 = 250,000 BTUs = 0.0003 kW × 250,000 = 75 kW

We note that 250,000 BTUs is equivalent to 263764 kJ

1 kWh is equivalent to 3600 kJ

10,000 kWh = 10,000 × 3600 = 36,000,000 kJ

The energy requirement for ten homes  for one year = 10 × 36,000,000 kJ = 360,000,000 kJ

At 50% efficiency, the energy produced per tire = 0.5 × 263764 kJ = 131,882 kJ

The electrical energy produced per tire = 131,882 kJ/tire

The number of tires required to power ten homes for one year = 360,000,000 kJ/  131,882 kJ/tire = 2,729.71293  ≈2,730 tires

The number of tires required to power ten homes  ≈2,730 tires.

An unknown solid is placed on a scale and has a mass of 2.5 grams. The solid then displaces 35 mL of water in a graduated cylinder. Find the unknown solid’s density.

Answers

Answer:

The unknown solid’s density is 0.071 [tex]\frac{g}{mL}[/tex]

Explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

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

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Archimedes' principle states that every body immersed in a fluid experiences a vertical and upward thrust equal to the weight of fluid dislodged. In other words, this principle says that the volume of the object is equal to the volume of the water displaced or displaced. So:

mass= 2.5 gramsvolume=35 mL

Replacing in the definition of density:

[tex]density=\frac{2.5 g}{35 mL}[/tex]

you get:

[tex]density=0.071\frac{g}{mL}\[/tex]

The unknown solid’s density is 0.071 [tex]\frac{g}{mL}[/tex]

Explanation:

You wont fail your quiz .

If a falling rock undergoes a Δv of 112ms due to a speed of 9.8 m/s2, it will take 11.4 seconds to fall.

What is speed?

The speed is the rate of change of position of an object with a given time of interval or per unit time then it is known as speed and it is the ratio of distance traveled to the time taken unit is meter per second.

The speed of an object is 9.8 m/s² distance traveled is 112m/s so the time will be,

                 Speed = distance / time

Substituting the value,

                  Time = distance/ speed

                  Time = 9.8 m/s² / 112m/s

                  Time =  11.4 seconds

Therefore, it will take 11.4 seconds to fall, if a falling rock undergoes a Δv of 112ms due to a speed of 9.8 m/s².
