Answer:

The crust is always made of different materials under the mountains than under the oceans.

Explanation:

Right answer

Mark me as brilliant and thank you.

Among the given statements option 4 is correct. The crust is thinner under the oceans than under the mountains. The composition of earth crust should vary from that under oceans.

The earth crust is made of rocks and soil made of different elemental compositions. The crest properties in region may varies in each region. The continental thickness of crest is always thicker than the oceanic crest.

The layer of granitic, sedimentary, and metamorphic rocks that makes up the continental crust is what gives rise to the continents and the continental shelves, or shallow seafloor regions adjacent to their shores. Since it is less dense than the mantle material, it "floats" on top of it.

Even though it is significantly thicker—typically 35 to 40 km vs the average oceanic thickness of roughly 7 to 10 km—continental crust is less dense than oceanic crust. Currently, continental crust covers about 40% of the Earth's surface.

The thinnest continental crust is found in rift zones, where it is finally split and replaced by oceanic crust after thinned by detachment faulting.  (both sides of the Atlantic Ocean, for example). Hence, option 4 is correct.

Answer:

Every magnet has two sides: a north pole and a south pole. We use these names because if you hang a magnet from a thread, the magnet’s north pole points (almost) towards the north direction.

This is because the Earth’s core (its centre) is a large, weak magnet. Your little, strong magnet lines up with Earth’s magnetic core, so it points north. That’s how a magnetic compass works.

Yes

Hey there!

We need to start this by finding the molar mass of (C₃H₅)₂S.

This molecule consists of 6 carbon atoms, 10 hydrogen atoms, and one sulfur atom. We need to add the molar masses of each atom up.

C: 6 x 12.01 = 72.06

H: 10 x 1.008 = 10.08

S: 1 x 32.07 = 32.07

-------------------------------

                    114.21 g/mol

Ok, now that we have established that the molar mass of (C₃H₅)₂S is 114.21 g/mol, we have 2.50 mol of (C₃H₅)₂S. If 1 mol has a mass of 114.21 g, then 2.50 mol will have a mass of 2.50 time 114.21.

2.50 x 114.21 = 285.525 grams

This should go to just three significant figures, so:

The mass of 2.50 mol of (C₃H₅)₂S is 286 grams.

Hope this helps!

Hello!

Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element.

So in short, the Correct Answer will be (D) an Element.

Hope that Helps! Have A Wonderful Day! ☺

Explanation:

Gold is an example of chemical element with symbol Au aurum and atomic number 79, lightly reddish yellow, dense, soft, malleable, and ductile metal.

Atomic number of an element  is defined as total number of protons present in the nucleus,  neutrons carry no net electrical charge, so it is the charge number of the nucleus.

atomic mass of an element can be defined as the atomic weight is measured total mass of an element’s atom, the total number of neutrons and protons in the nucleus of an atom.

Both Atomic mass and an atomic number of elements are closely related if  atomic number is high, then the atomic mass is also said to be high.

That would be SiBr4, hope this helps ^^

Silicon pentabromide has the formula SiBr₅ . It is a covalent compound formed by electron sharing between Si and Br atoms.

Silicon pentabromide is a covalent compound formed by sharing of electrons between Si and Br atoms. Silicon is 14th group element and it has 4 valence electrons. It needs 4 more electrons to achieve octet.

Br is 17th group element having 7 valence electrons. It needs 1 more electron to achieve octet. Thus, it combines with other atoms by gaining or sharing electrons.

The compound SiBr₅ is in fact does not exist. Because Si does not have 5 electrons in its valence shell to share with each Br. But Br can share its one electron with Si, and Si will gain  9 electrons in its valence shell and thus deviates from rule of octet.

Answer:

The mass of 21.05 moles of iron(III) sulfide is 4,372.085 grams.

Explanation:

Iron (III) sulfide is a chemical compound with the formula Fe₂S₃.

Being the molar mass of the elements:

then the molar mass of iron sulfide (III) is:

Fe₂S₃= 2* 55.85 g/mole + 3* 32 g/mole=  207.7 g/mole

Molar mass is the amount of mass that a substance contains in one mole. Then the rule of three can be applied: if in 1 mole of iron (III) sulfide there are 207.7 grams, in 21.05 moles how much mass is there?

[tex]mass=\frac{21.05 moles*207.7 grams}{1 mole}[/tex]

mass= 4,372.085 grams

The mass of 21.05 moles of iron(III) sulfide is 4,372.085 grams.

Answer:

V₂ = 1.17 L

Explanation:

Given data:

Initial volume of balloon = 1.25 L

Initial temperature = 35°C

Final temperature = 15°C

Final volume = ?

Solution:

Initial temperature = 35°C (35+273.15K = 308.15 K)

Final temperature = 15°C (15+273.15 K = 288.15 K)

The given problem will be solve through the Charles Law.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.25 L × 288.15 K / 308.15 k

V₂ = 360.2  L.K / 308.15 k

V₂ = 1.17 L

A substance's density tells you what its mass per unit of volume is. In this case, you know that lead has a density of

11.3 g/cm

, which means that each

cm

of lead will have a mass of

11.3 g

.

Now, your cube has a volume of

Answer:

8 electrons

Explanation:

As per the octet rule, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.

There should be 8 electrons in the outer energy level.
